Following a recent Windows 11 update, users may experience a slowdown in performance. This can occur due to background tasks run by the system after updates, such as search reindexing and file optimization. To mitigate this, it is suggested to leave the computer idle for about 30 minutes to complete these tasks, followed by a restart to trigger final optimizations.
Addressing Update-Induced Sluggishness
If performance issues persist, verify if the update is responsible by checking the KB number in Settings > Windows Update > Update History. If the issue is widespread, consider uninstalling the update from Settings > Windows Update > Update History > Uninstall Updates and await an official fix from Microsoft.
Optimizing System Performance
Free up disk space by uninstalling unnecessary applications under Settings > Apps > Installed apps, deleting temporary files via Settings > System > Storage > Temporary Files, and enabling Storage Sense. It's advisable to maintain 15–20% free space for optimal performance.
Tweaking Settings for Speed
Review Task Manager to disable any re-enabled startup apps. Adjust power settings to Best Performance in Settings > System > Power & Battery. Limit background app activity by setting permissions to Never for unnecessary apps under Apps > Installed Apps > Advanced options. Lastly, ensure visual effects or performance-impacting options are not inadvertently turned on.
Most post-update slowdowns resolve naturally once all background tasks are completed. For persistent issues, reverting specific settings altered by the update can restore system performance to expected levels.
