Desktop PC suddenly slow to start-up.

Yes—installing Windows updates and optional driver updates can help if the slow startup is caused by a driver or non-critical update that improves performance or compatibility.

For Windows 11, the recommended order is:

1. Go to Start > Settings > Windows Update > Check for updates.
2. Install any available regular updates with Download & install.
3. Then go to Start > Settings > Windows Update > Advanced options > Optional updates.
4. If optional updates are available, select them and choose Download & install.

Since startup apps were already checked, the next useful checks are:

1. Run a malware scan
   • Go to Start > Settings > Privacy & security > Windows Security > Virus & threat protection.
   • Select Quick scan.
2. Check storage space and clean temporary files
   • Go to Start > Settings > System > Storage.
   • Turn on Storage Sense.
   • Select Configure Storage Sense or run it now, then Clean now.
3. Review Task Manager for heavy processes
   • Press Ctrl + Shift + Esc.
   • On Processes, close apps not in use.
   • Review Performance and Startup apps for anything using high resources.
4. Set visual effects for performance
   • Open Start, type Adjust the appearance and performance of Windows, and open it.
   • On Visual Effects, select Adjust for best performance.
5. Restart and test with only essential apps open
   • Select Start > Power > Restart.

If the slowdown started very recently after an update, one Microsoft Q&A accepted answer notes this can be a compatibility issue with drivers and a recent update. In that case, System Restore back to a point when startup was normal is one option, or waiting for a newer update may help.
