windows11 not updating

[larkhillandy]

Hi, I bought a reconditioned computer with windows 11 installed back in April 2024 .
Update history shows it did 3 updates when set it up and then 2 more up to October 2024. After that it stopped updating. I've not had time to do anything about it until today when I contacted Microsoft support.
The guy remote linked to the computer and told me after running PC health check that the processer on my computer was not supported and said that I need to contact my computer supplier.
I said that it had been doing updates before but he just ignored this and passed the buck. It's running a Intel core i7-2600@3.40ghz.
Any ideas as to proceed?

Thanks for the detailed info! Your situation is actually quite common for reconditioned PCs running Windows 11 on unsupported hardware. Here’s what’s going on and some steps you can take:

Why Updates Stopped​

• The Intel Core i7-2600 is not officially supported by Windows 11. Microsoft may occasionally block updates—especially feature upgrades and sometimes cumulative/security ones—on unsupported hardware.
• Initially, updates might trickle through, but eventually, Windows recognizes the unsupported processor and halts them.

Why It Worked Before​

• When Windows 11 is freshly installed on unsupported hardware, updates may work for a few months. But once Microsoft pushes new policy checks, updates get restricted.

What Are Your Options?​

1. Manual Updates:
   • You can download and install monthly cumulative updates manually from the Microsoft Update Catalog. However, this is only a temporary workaround and is not recommended long-term, as it's easy to miss important security patches or break the system.
2. Bypass Restrictions (Not Officially Supported):
   • There are community scripts and registry tweaks (like using AllowUpgradesWithUnsupportedTPMOrCPU in the registry) that can sometimes "trick" Windows Update into continuing, but they’re not always reliable and can be risky for data or stability.
3. Stay on Windows 11 as-is:
   • You can keep running Windows 11 without updates, but this introduces major security risks. Not recommended for daily use, especially if the PC is connected to the internet.
4. Revert to Windows 10:
   • Windows 10 is fully supported on your hardware until October 2025, including updates and security patches. This is the least hassle and most secure option.
5. Upgrade Hardware:
   • If you want to keep Windows 11 and get all updates, you’ll need a PC with a supported Intel 8th-gen CPU or newer.

My Practical Recommendation​

• Your safest bet:
  Back up your data and install Windows 10. You’ll get seamless, automatic updates—no headaches, no weird workarounds, and full support until at least October 2025.
• If you want to keep experimenting with Windows 11:
  I can give you step-by-step guidance to try the unofficial registry bypass or manual updating process, but again, it carries some risk.

Let me know which route you’d like to take or if you want instructions for a specific step.

 

[datawizard0103]

Your i7-2600 processor is not supported by Windows 11, so Microsoft has stopped automatic updates. You can install Windows 10, which is supported until October 2025, manually install updates, bypass the CPU check, or upgrade the hardware.

 

[ChatGPT]

Yep — that summary is basically correct. A few clarifications and safe next steps.

• i7-2600 (Sandy Bridge, 2nd‑gen Intel) is not on Microsoft’s supported processor lists for Windows 11, so a machine with that CPU won’t be considered eligible for the official Windows 11 upgrade path. (learn.microsoft.com)
• Microsoft’s position is that installing Windows 11 on unsupported hardware is possible, but unsupported devices “will no longer be guaranteed to receive updates” (including security updates). In short: you can force or install Windows 11 on an older CPU, but Microsoft may refuse to deliver future Windows updates to that device. (support.microsoft.com)
• Windows 10 support (security updates, feature updates, official technical support) ends on October 14, 2025. If you want to stay on Windows 10 past that date you’ll need an Extended Security Updates (ESU) option or other paid extended support, or move to a supported OS/hardware. (support.microsoft.com, microsoft.com)
• If you want to try Windows 11 on that machine there are known bypasses:
  • Microsoft previously documented a registry value (HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup → AllowUpgradesWithUnsupportedTPMOrCPU = 1) to allow upgrades on unsupported CPUs/TPM, and lots of community tools / boot‑time registry tricks (LabConfig) can bypass TPM/CPU/SecureBoot checks for clean installs. These work, but they’re explicitly unsupported and carry risk (instability, missing security features, and blocked updates). (bleepingcomputer.com, tomshardware.com)
  • Note: Microsoft has removed/changed some guidance around bypasses over time and does not recommend them; relying on them can leave you unpatched. (neowin.net)

Practical options (pick the one that fits you):

1. Stay on Windows 10 (recommended short term)
   • Keep Windows 10 and install updates until Oct 14, 2025. Consider ESU if you need more time. This is the safest route if you need security updates. (support.microsoft.com)
2. Upgrade hardware
   • Replace the motherboard + CPU (and likely RAM) with a platform that meets Windows 11 requirements, or buy a new Windows 11 PC. For an i7‑2600 you can’t move to a modern Intel CPU without a new board. This gives a clean, supported path to Windows 11 and future updates. (intel.com)
3. Install Windows 11 on unsupported hardware (unsupported)
   • Use Microsoft’s registry bypass or LabConfig / Rufus/modified ISO methods to install Windows 11. Expect warnings, possible feature loss (TPM/security features), and the possibility Microsoft won’t deliver all future updates. Back up first and be prepared to roll back to Windows 10. (bleepingcomputer.com, tomshardware.com)
4. Stick with Windows 10 but plan migration
   • Use the remaining time before Oct 14, 2025 to prepare: back up data, test apps on Windows 11 (or alternative OS), and budget for hardware replacement. (support.microsoft.com)

If you want, I can:

• Check your current PC’s compatibility with the PC Health Check steps and point to the exact checks to run.
• Give precise registry snippets and step‑by‑step for the bypass (with all the warnings) if you still want to try Windows 11 on that i7‑2600.
• Outline a low‑cost upgrade path (motherboard/CPU/RAM combos) or recommend replacement PC options.

Yes — I can outline a few realistic, low‑cost upgrade paths (and a buy‑new alternative) so your PC will be on a Windows‑11‑supported platform. Below I give three practical routes (cheap/used upgrade, value new platform, and buy‑new PC), rough cost ranges, what you’ll need to change, and the next steps (including licensing checks). I’ve cited Microsoft’s supported‑CPU guidance and a couple of third‑party comparisons to back the recommendations.
Quick reality check first

• Microsoft publishes an official list of CPUs supported for Windows 11 (Windows 11 v24H2 list); your i7‑2600 (Sandy Bridge) is not on the supported list, so replacing the motherboard/CPU is the way to get onto a supported platform. (learn.microsoft.com)

Option A — Lowest cost: used/refurb platform swap (best value if you’re handy)

• What you change: buy a used motherboard + CPU + DDR4 RAM (your i7‑2600 uses DDR3 so RAM must be replaced). Keep your existing storage (SSD/HDD), case, PSU if compatible.
• Good value CPU choices (used or refurbished): AMD Ryzen 5 3600 / Ryzen 5 5600, or Intel Core i5-12400 / i5-13400. These give solid everyday performance and are frequently available used or as refurbished parts at good prices. Benchmarks show Intel i5-12400 and AMD Ryzen 5 5600 are both very competitive value picks. (nanoreview.net, cpu.userbenchmark.com)
• Typical parts list (example):
  • B450/B550 AM4 motherboard + Ryzen 5 3600/5600 OR B660/B760 motherboard + i5-12400/13400
  • 16 GB (2×8GB) DDR4‑3200
  • Reuse current SSD/HDD or add NVMe for best responsiveness
• Estimated (used/refurb) cost range: roughly $150–$350 total if you source used parts (varies a lot by market/location). New low‑end motherboards + CPU + 16GB will be higher.
• Pros: lowest outlay, good performance uplift, keep your current case/drive.
• Cons: BIOS/drivers for older boards may be quirky; warranty/long‑term future‑proofing limited.

Option B — Value new platform (recommended if you want new parts with warranty)

• What you change: buy a new motherboard/CPU and DDR4 RAM (or move to DDR5 if you want future proofing — more expensive).
• Recommended mid‑range new picks (best price/performance in 2024–25 era): Intel 12th/13th gen i5 (i5‑12400 / i5‑13400) on B660/B760 DDR4 boards or AMD Ryzen 5 5600/7600 on B550/X570 (AM4 or AM5 for newer Ryzen). These give long life and Windows 11 compatibility. (nanoreview.net, windowscentral.com)
• Estimated new cost range: roughly $300–$550 (CPU + motherboard + 16GB DDR4) depending on exactly which CPU and whether you pick DDR4 (cheaper) or DDR5 (costlier).
• Pros: new warranty, more reliable, easier driver support and firmware updates.
• Cons: higher upfront cost than Option A.

Option C — Buy a new Windows 11 PC (often the simplest)

• What you change: replace the whole PC with a new refurbished or new Windows 11 system (desktop or mini‑PC).
• Why consider: sometimes a new/refurbished mini‑PC or OEM desktop (Ryzen/Intel modern CPU, 8–16GB RAM, NVMe SSD) can be in the same price bracket as doing a partial upgrade, and it avoids part compatibility headaches. Deal sites and clearance events often have attractive prices. Example: budget mini‑PCs and clearance laptops show very low price points for usable Windows 11 machines. (tomsguide.com, techradar.com)
• Estimated cost: $300–$650 depending on specs and sale pricing.
• Pros: simplest, warranty, Windows 11 preinstalled and supported.
• Cons: you must migrate data and (possibly) re‑buy any specialty software.

Windows license note (important)

• Check whether your current Windows 11 Pro is OEM or Retail. OEM licenses are typically tied to the original motherboard and usually cannot be transferred; Retail licenses can be moved to a new machine (one active machine at a time). You can check license type on your PC with slmgr commands (or via Settings → Activation). The community and Microsoft docs show retail licenses can be transferred and slmgr /dlv shows license info; if you have OEM, you may need to buy a new license or call Microsoft support to discuss options. (lifewire.com, answers.microsoft.com)
• If your license is linked to your Microsoft account (digital license), moving activation is easier for retail licenses. If it’s OEM (preinstalled), it is probably non‑transferable. (answers.microsoft.com)

Step‑by‑step next actions I recommend

1. Tell me your budget and preference (used parts vs new parts vs buy new). If you’re not sure, give a price range you’d like to stay in.
2. Check your current Windows license type:
   • Open Admin Command Prompt and run: slmgr /dlv
   • Note whether it says “Retail” or “OEM” (or “Retail Channel / OEM Channel”). If you want, paste the non‑sensitive parts of the output here (don’t post any full product keys).
   • If Retail, you can transfer to a new board/PC (you should deactivate/uninstall on old system first). If OEM, you’ll likely need a new license. (lifewire.com, answers.microsoft.com)
3. Decide route (A, B or C above). If you pick A or B, tell me:
   • Whether you want AMD or Intel (both good — AMD often has better price/perf at some tiers; Intel 12th–13th gen remains strong for single‑thread tasks).
   • Whether you prefer to keep using DDR4 (cheaper, more used options) or move to DDR5 (newer, more expensive).
4. If you want, I’ll:
   • Build a specific parts list for your budget (exact motherboard model, compatible CPU, RAM SKU, and estimated price links).
   • Provide step‑by‑step install checklist (backup, prepare Windows media, driver order, BIOS settings).
   • Help check if your OEM key can be moved or how to activate on the new system.

Example quick recommendation (if you want minimal cost with good longevity)

• Pick: Ryzen 5 5600 + B550 motherboard + 16GB DDR4 3200 + reuse your SSD. That’s a good balance: strong single/multi‑core, low power, widely supported and usually available used/refurb or new at good value. If you prefer Intel, i5‑12400 + B660 (DDR4) is an excellent alternative. Benchmarks and value comparisons back these as solid choices. (cpu.userbenchmark.com, nanoreview.net)

If you tell me:

• your absolute budget (e.g., $200 used, $400 new parts, $600 replace PC), and
• whether you’re comfortable installing parts yourself,
  I’ll draft a specific parts list (motherboard/CPU/RAM model numbers), assembly checklist, and an estimated current price range with shopping tips.

[ChatGPT]

Good — below are three concrete, budget‑tiered upgrade packages (parts with model suggestions), a clear assembly/install checklist, estimated price ranges, and shopping/compatibility tips. I’ll call out Intel vs AMD options where useful. I’ve included next steps for Windows activation/licensing at the end. These recommendations assume you’re replacing the i7‑2600’s motherboard/CPU and its DDR3 RAM (you must move to DDR4 or DDR5).
Short context reminder: the i7‑2600 (Sandy Bridge) is not on Microsoft’s supported CPU list for Windows 11, so a board+CPU swap (or a new PC) is required for a fully supported Windows‑11 system.
If you want, tell me which budget you prefer and whether you want AMD or Intel; I’ll turn the chosen option into shopping links and an exact parts list to buy.
1) Budget goal: ≈ $150–$300 — “Lowest cost / used or refurb parts” (you assemble)

• Target: get a modern CPU that Windows 11 supports, reuse case/PSU/drive.
• Suggested kits (pick one AMD or Intel path):
  AMD (best value used/refurb):
  • CPU: AMD Ryzen 5 3600 or Ryzen 5 5600 (used/refurb).
  • Motherboard: B450 or B550 ATX/mATX (e.g., MSI B450 Tomahawk Max II or Gigabyte B550M DS3H) — confirm BIOS support for the CPU.
  • RAM: 16 GB (2×8GB) DDR4‑3200 (Corsair Vengeance LPX or Crucial Ballistix).
  Intel (used/refurb / sometimes better single‑thread in some apps):
  • CPU: Intel Core i5‑12400 (used/refurb or new budget SKU).
  • Motherboard: B660 (DDR4) microATX/ATX (e.g., MSI PRO B660M‑A DDR4).
  • RAM: 16 GB (2×8GB) DDR4‑3200.
• Typical (used/refurb) price estimate: $150–$350 total for CPU + board + 16GB RAM if you shop used marketplaces. New entry kits will be somewhat higher.

Why this option:

• Lowest cash outlay while getting a Windows‑11‑eligible CPU. Good if you’re comfortable flashing BIOS if needed and buying used parts.

2) Mid budget: ≈ $300–$550 — “New parts, best warranty/value” (recommended if you want reliability)

• Target: brand‑new CPU + motherboard + RAM (keep existing drives/case/PSU if compatible).
• Suggested kits (pick AMD or Intel):
  AMD (value / easy):
  • CPU: AMD Ryzen 5 5600 (new).
  • Motherboard: B550 ATX (e.g., ASUS TUF Gaming B550‑Plus or MSI B550‑A PRO).
  • RAM: 16 GB (2×8GB) DDR4‑3200 (match the board QVL).
  Intel (alternative):
  • CPU: Intel Core i5‑12400 or i5‑13400 (new).
  • Motherboard: B660 / B760 (DDR4 variant to save money) — e.g., MSI PRO B660M‑A DDR4.
  • RAM: 16 GB (2×8GB) DDR4‑3200.
• Estimated new cost: $300–$550 for CPU + motherboard + 16GB DDR4, depending on exact models and sales. New parts give warranty and fewer firmware/compatibility headaches.

Why this option:

• New warranty, easier firmware/motherboard support, long term reliability — good balance of price and future life.

3) Replace PC: ≈ $300–$700 — “Buy new / refurbished Windows 11 PC” (simplest)

• Target: pick a prebuilt OEM desktop or mini‑PC that ships with Windows 11 and is supported.
• Examples to look for: refurbished Dell/HP/Lenovo desktops or mini‑PCs with recent Intel (12th gen+) or Ryzen (5000 series or newer) CPUs and NVMe SSDs. Deal sites and clearance events often put capable systems in the $300–$650 band.
• Why this option: no hardware compatibility drama, warranty, Windows 11 preinstalled and activated.

Important Windows license note (read before swapping motherboard)

• If your Windows 11 Pro key is OEM (preinstalled), it’s usually tied to the original motherboard and typically cannot be transferred; retail licenses can be moved to a new machine. You can check license type with slmgr /dlv from an elevated command prompt — look for “Retail” vs “OEM”/“OEM Channel”. If Retail (digital license linked to your Microsoft account) transferring is straightforward; if OEM you may need a new license or call Microsoft.

Assembly & install checklist (step‑by‑step)

1. Back up everything
   • Full backup of Documents, Desktop, browser profiles, and any activation keys/licenses. Create a system image if you want an easier rollback.
2. Confirm parts compatibility before buying
   • CPU fits motherboard socket and BIOS version (check board vendor CPU support list). If the board needs a BIOS update to support your chosen CPU, you may need a vendor “BIOS flash” service or choose a board that supports the CPU out of the box.
3. Gather tools
   • Phillips screwdriver, static strap (or touch grounded metal), thermal paste (if not included), USB for Windows installer.
4. Build steps (high level)
   • Remove old motherboard/CPU: power off, unplug, discharge, remove case side panel.
   • Install CPU into new socket (align triangle), install CPU cooler and fresh thermal paste per cooler instructions.
   • Install RAM sticks into correct DIMM slots (consult manual).
   • Mount motherboard, connect 24‑pin + CPU 8‑pin power connectors, front panel headers, SATA/NVMe cables.
   • Confirm PSU has required connectors and wattage for your new CPU + GPU if present.
5. First boot / BIOS
   • Power on, enter UEFI/BIOS, load Optimized Defaults, set SATA to AHCI (if applicable), ensure UEFI (not legacy) mode, and enable TPM (PTT on Intel / fTPM on AMD) and Secure Boot if supported. Convert disk to GPT (mbr2gpt) if needed before enabling UEFI.
6. Update BIOS and drivers
   • Update the motherboard BIOS to the latest stable version (follow vendor instructions). Install chipset drivers first after OS install.
7. Windows install / activation
   • Create Windows 11 installer (Media Creation Tool) or use an OEM image if buying a new PC. Install Windows — keep files or clean install as you prefer. If your Windows license is retail and linked to your Microsoft account, sign in with the same Microsoft account and use troubleshooting → activation → “I changed hardware on this device” to reactivate. If OEM, plan to purchase a new license.
8. Post‑install checks
   • Run Windows Update, install motherboard chipset, LAN/Wi‑Fi, audio and GPU drivers. Enable Windows Security features you need (BitLocker only after TPM enabled).

Shopping tips & warnings

• BIOS compatibility: if buying older B450/B550 boards for modern Ryzen CPUs, check that the board has the BIOS version for the CPU (or pick boards sold as “Ryzen 5000 ready” or new stock).
• Buy from reputable sellers (Newegg, Amazon sold by reputable stores, local shops with returns) or check seller ratings on used marketplaces. Check return policy and DOA handling.
• Avoid very cheap unknown brands for motherboards and PSUs — a bad PSU can kill components.
• If you lack confidence updating BIOS or performing a board swap, local shops can do the physical swap and BIOS work for a modest fee.
• Consider adding an NVMe SSD if you currently use an HDD — huge real‑world responsiveness gain for small cost.

Price estimates (very approximate ranges; market varies)

• Used kit (CPU + board + 16GB DDR4): $150–$350.
• New mid kit (CPU + board + 16GB DDR4): $300–$550.
• New/refurbish full PC: $300–$700 depending on specs and sale timing.

Useful checks / commands (quick)

• Check license type: open elevated Command Prompt → slmgr /dlv (look for “Channel” / “License Type”).
• PC Health Check: run Microsoft PC Health Check to confirm requirements and see exact failures (TPM, Secure Boot, CPU).
• Convert MBR→GPT if switching to UEFI: mbr2gpt /validate /allowFullOS and then /convert (backup first).

What I can do next for you (pick any)

• Build an exact shopping list for one of the three budgets above with current retailer SKUs and price checks (I’ll need your budget and whether you prefer AMD or Intel).
• Walk you through the step‑by‑step assembly and BIOS setup for the exact parts you buy.
• Help check your current Windows activation status (ask you to paste the slmgr /dlv non‑sensitive lines) and advise on transfer/activation steps.

Pick one: A) I want a parts list for a $200 used budget, B) I want a new parts list for ~$400, or C) show me good prebuilt/refurb Windows 11 PCs around $500–$650 — and tell me if you’ll install yourself or want prebuilt. I’ll draft the exact SKUs and an actionable shopping list.
