Hello, Dnhap1 Helpdesk (DNHA)
Welcome to the Microsoft community.
Thank you for your feedback. I understand that you are experiencing post-update performance issues. Here are some troubleshooting options:
1. Confirm the root cause of the problem
Check the update history:
Go to Settings → Windows Update → Check Update History to confirm whether the issue is caused by a specific patch (e.g. KB5034441).
If the problem patch is identified, you can try to uninstall it:
Go to Settings → Windows Update → Uninstall Updates, select the corresponding patch and delete it.
2. Optimize system resource usage
Identify high load processes:
Press Ctrl + Shift + Esc to open Task Manager.
Sort by CPU, Memory, and Disk to find the processes with 100% occupancy rate for a long time.
If it is a system process (e.g. System, Antimalware Service Executable):
Disable the SysMain (formerly SuperFetch) service (recommended for SSD users):
Press Win + R, type services.msc, find SysMain → Right-click Properties → Startup type to Disabled → Restart.
3. Adjust virtual memory and power plan
Increase virtual memory (to relieve memory pressure):
Search and open “Tune Virtual Memory”.
Uncheck “Automatically manage paging file size” → Select NVMe hard disk → Set Custom size (Initial value = 1.5 times physical memory, Maximum value = 3 times).
Switch the power plan:
Go to Control Panel → Power Options.
Select “High Performance” or “Superior Performance” (Windows 11 needs to be enabled manually).
4. you can test if it is the same issue in safe mode
On the Windows logon screen, hold down the Shift key while selecting “Power > Restart”.
After restarting, > Restart > Startup Settings > “Advanced Options Troubleshooting”
Select 4 or 5.
5. Check SSD Health and Settings
Make sure TRIM is enabled:
fsutil behavior query DisableDeleteNotify # Return 0 to indicate TRIM is enabled.
Update the SSD firmware:
Visit the hard disk manufacturer's official website (e.g. Samsung, Western Digital) and download the firmware update tool.
Turn off disk indexing:
Right-click the NVMe drive → Properties → uncheck “Allow indexing of this drive's contents”.
6. Disable visual effects:
Go to Settings → System → About → Advanced system settings → Performance settings → Adjust for optimal performance.
7. Try an in-place upgrade, this will refresh your Windows and will not delete your data, but for important data it is still recommended that you back up.
