Solved Explorer not responding

Have been searching for a solution here and elsewhere with query "Win 11 explorer not responding" it just stopped responding yesterday, wasn't doing anything unusual - just browsing files. Have tried various solutions with no success. Using Microsoft Files to explore in lieu of.
Thanks in advance for any help.

First I would suggest you make sure you have no corrupt system files that is causing this problem. Open a command prompt as administrator and type sfc /scannow
Pay attention to the scan results to see if SFC found anything it could not repair. If it found corruption it could not fix followup with this command (note the spaces)
dism /online /cleanup-image /restorehealth
Restart computer

(Note-you can follow up with another sfc /scannow command to make sure that dism repaired the files if you wish)

You can also verify there are no software conflicts by performing a clean boot. If it doesn't happen in a clean boot, you have some software conflicting with Windows. Brink's procedure will help you weed out which one. Perform a Clean Boot in Windows 11 to Troubleshoot Software Conflicts Tutorial

Edit: If none of that works, I would recommend a repair install. Repair Install Windows 11 Repair Install Windows 11 with an In-place Upgrade Tutorial

Thanks for the replies, it's late now (in Europe) so I will have a go using your advice tomorrow (Wednesday) after work

Thanks again glasskuter
I ran sfc /scannow and nothing was found to repair. Rather than try any other solution and although cautious, I went ahead with your second suggestion and reset the PC keeping files and apps etc, all is good now and all back to normal
