The “Microsoft driver” thing is almost certainly
not the root cause here (it’s normal for the Ryzen “Processor” entries and HID keyboard/mouse to show Microsoft as the provider). Your symptom set screams
short system-wide stalls (DPC/ISR latency) or power/USB/network driver latency, which then
looks like “keyboard/mouse problems” because input queues get stuck during the stall and then “catch up” (the
kkkkkkkk effect).
Below is the fastest way I’d isolate this on your exact platform (Ryzen 5600G + ASUS B550M-Plus WiFi II), with the least guesswork.
1) First: confirm whether you’re on an optional preview update
Please go to
Settings → Windows Update → Update history → Quality updates and look for
KB5074105 (late January 2026 optional Release Preview update that targets build families in the
26100/26200 range).
noticeably worse right after that update, temporarily
uninstall it (Settings → Windows Update → Update history → Uninstall updates) and test for a day.
- If the issues pre-date that update, keep going—this is likely platform driver/power latency.
2) Do the 10-minute test that identifies the actual culprit: LatencyMon
Your “freeze 1–2 seconds + input goes weird during the freeze” is classic DPC latency behavior. LatencyMon will usually point at the driver/module responsible (ACPI, network, USB, GPU, etc.), which lets us fix the
real problem instead of swapping random drivers.
A solid, proven workflow is: run LatencyMon while reproducing the issue, then look at the highest DPC/ISR offenders and address them one-by-one.

What to watch for
- If you see ACPI.sys or power-management related items high on the list → power state transitions can be stalling the system.
- If you see network drivers (very common on Realtek Wi‑Fi/BT combos) → update/rollback that specific driver.
- If you see USB hub / HID / Bluetooth stack drivers → power management or BT/Wi‑Fi driver packages are often involved.
If you paste a screenshot of the
Drivers tab (top ~10), I can tell you exactly what to change.
3) Platform-specific fixes that commonly stop 1–2 second stalls on AM4/B550
A) Update these from ASUS (not Windows Update)
On B550 boards, Windows Update sometimes supplies “works-but-not-great” drivers.
From your ASUS support page for
B550M-Plus WiFi II, install (in this order):
- Latest BIOS (very important on AM4; also resets a lot of weird stability edge cases)
- AMD Chipset driver (from ASUS or AMD—either is fine, but make sure it’s current)
- Wi‑Fi driver and Bluetooth driver (these are big suspects given your “mouse erratic” + general UI stalls)
B) Temporarily eliminate Wi‑Fi/Bluetooth as variables (simple test)
For one evening of testing:
- Disable Wi‑Fi and Bluetooth in Device Manager (or BIOS, if you prefer)
- Use Ethernet (if possible)
- Use a wired USB mouse/keyboard (no receiver, no BT)
If your problems disappear, you’ve essentially proven it’s a wireless/BT driver or power-management interaction (not your Logitech “Microsoft driver”).
4) Power management changes that often fix stutter (reversible)
These are exactly the kind of conservative changes that often remove DPC spikes when ACPI/USB/PCIe power transitions are involved.
Try on your main power plan (plugged in):
ower Options
→ Change plan settings → Advanced**
- Set:
- PCI Express → Link State Power Management: Off
- USB settings → USB selective suspend: Disabled
- Processor power management → Minimum processor state: try 10% (plugged in) instead of 5%
Then in
Device Manager:
- For USB Root Hub entries and Bluetooth adapter (if present):
- Properties → Power Management
- Uncheck “Allow the computer to turn off this device to save power”
(These may slightly increase power use, but on a desktop they’re usually worth it if they stop system-wide stalls.)
5) The “permissions blocked even though I’m admin” symptom
That one often comes from
security features, not “being not-admin”:
Check:
- Windows Security → Virus & threat protection → Ransomware protection → Controlled folder access
- If ON, it can block certain apps from writing/changing things even for admins.
- Windows Security → App & browser control → Smart App Control
- SAC can block untrusted apps/installers. Recent builds changed SAC behavior/toggles.
Also: if you’re trying to change permissions on system folders, s that require elevation (and some things are intentionally locked down). But the key point is: this is usually
policy/security, while your freezes are
latency/driver.
6) Why AMD/Logitech “won’t replace Microsoft drivers”
Just to close the loop on your original driver concern:
- Ryzen CPU showing Microsoft provider in Device Manager is normal.
- Keyboard/mouse being Microsoft HID is normal; Logitech customization comes from apps like Logi Options+ rather than a new kernel driver.
So I would stop fighting that and focus on the drivers that actually cause stalls (chipset, Wi‑Fi/BT, USB, storage).
Two questions (quick) that will let me give you a very specific “do X, Y, Z” order:
1) Are your Logitech devices connected via
Bluetooth, a
USB receiver, or
wired?
2) In LatencyMon, what are the top 5 entries on the
Drivers tab (name + highest execution time)?
If you answer those, I can narrow this down to (most likely) Wi‑Fi/BT driver vs ACPI/power vs USB hub power saving in one round.
