Upgrade Your Old PC to Windows 11: Step-by-Step Guide and Tips

Upgrading to Windows 11 has become a hot topic since Microsoft's announcement that Windows 10 will cease receiving security updates on October 14, 2025. This change compels many users with outdated or incompatible hardware to consider their options. For those who find their computer's specifications falling short of the minimum requirements needed for a Windows 11 upgrade, fear not; there are potential alternatives available.

Understanding the Minimum System Requirements​

Before we delve deep into the upgrade process, let’s outline Microsoft's minimum system requirements for Windows 11. This serves as a benchmark to determine if your PC is potentially eligible for the upgrade:

• Processor: 1 GHz or faster with 2 or more cores on a compatible 64-bit processor
• RAM: 4 GB or more
• Storage: 64 GB or more
• System Firmware: UEFI, Secure Boot capable
• TPM: Trusted Platform Module version 2.0
• Graphics Card: DirectX 12 or later with WDDM 2.0 driver
• Display: >9" with 720p resolution

  The Roadblock: TPM 2.0​

  A significant barrier for many older PCs is the requirement for TPM 2.0. Many computers built in the early 2010s housed TPM 1.2, making them ineligible for a straightforward upgrade. Fortunately, bypassing this requirement is possible, although it comes with certain risk factors. Note: Users should proceed with caution. Altering registry settings can impact computer stability and security.

  Step-by-Step Guide to Upgrade​

  If your PC is rocking an older TPM version or doesn’t meet the other specifications required for Windows 11, follow these steps:
  1. Open the Registry Editor:
     • Click on the taskbar’s search bar and type ‘Registry Editor’. Click on the first result.
     []Navigate to the Required Registry Path:
     • Use the navigation panel on the left to follow this path:

        HKEY_LOCAL_MACHINE > System > Setup > MoSetup

     []Create a New Entry:
     • Right-click in an empty space within the MoSetup folder, and hover over New, then select DWORD (32-bit) Value.
     []Name the New Value:
     • In the dialog box that appears, name the new entry AllowUpgradesWithUnsupportedTPMorCPU.
     []Modify Value Data:
     • Double-click on the new entry and change the Value data to 1. This action will allow upgrades even with unsupported CPUs or TPM versions.
     []Confirm Changes:
     • After setting the value, click OK.
     []Download the Windows 11 ISO:
     • Go to the official Windows 11 download page. There, you can obtain the ISO file suitable for your x64 devices.
     []Install Windows 11:
     • Launch the downloaded ISO file. In the File Explorer, select Setup.exe and follow the prompts to start the upgrade process.

       Alternative Methods​

       If the above method feels risky or complex, consider performing clean installations or exploring avenues like the PC Health Check app to ascertain your system's compatibility. This app indicates readiness for Windows 11 and suggests improvements.

       Managing Expectations​

       Using the workaround comes with caveats:
  []Unsupported PCs may experience instability or limited features. []Users may find some functions (like security-related features) non-functional due to the lack of TPM 2.0. []Always back up your data before attempting any major upgrade.
