Obvious system stuttering occurs after a Windows update, and boot‑up as well as desktop entry time increases significantly.
First, try uninstalling the recently installed Windows update
Navigate to: Settings → Windows Update → Update history → Uninstall updates
Locate the recently installed quality update (usually KB‑prefixed), then select Uninstall.
If you cannot access Settings normally:
a. Press and hold the power button to force‑shutdown the device;
b. Repeat the power‑on / force‑shutdown cycle 2‑3 times to enter the Windows Recovery Environment;
c. Select: Troubleshoot → Advanced options → Uninstall Updates → Uninstall latest quality update
Reboot the computer upon completion and check whether system performance is restored.
If the issue persists after uninstalling the update
Further system file inspection is recommended. Open Command Prompt as Administrator and run the command below:
sfc /scannowOnce finished, execute:
DISM /Online /Cleanup‑Image /RestoreHealthThis repairs potentially corrupted Windows system components.
If the above steps fail to resolve the problem
Given the current symptoms: boot time exceeds 20 minutes, slow desktop loading after login and severe system response lag,
the system environment may have been heavily compromised.
Under such circumstances, please back‑up important data, then reinstall the Windows operating system.
Reinstallation can fully eliminate issues caused by faulty Windows updates, corrupted system files, driver conflicts and abnormal software environments.
