Why Does Windows 10/11 Copy and Paste Stop Working After A While?

But when mine goes out, Notepad and any others don't copy/paste, either, so it's not just an Office problem.

I feel your pain, LOL, I too have a wife that is willing to make a trade. After working with Dell, who is no help and Microsoft Level 3 for almost 5 months we still don't have a fix. I took my P/C to a specialist who did a TOTAL reformat of the hard drive and reloaded Windows 11 from a USB drive and Office from Microsoft and the P/C worked for 3-days and then failed, cost $135. I can't believe that Dell is allowing P/C's to be sold with these issues. If you read the forum, you will see that a user purchased a new ACER and has the same issues. I have a call scheduled today with Level 3 and will push the issue to get engineering involved as this is unacceptable for people who rely on this function to perform their job.

Add my wife as another user with a brand new Dell with Windows 11 Home pre-installed - which I upgraded to Pro to see if it fixes the problem - that exhibits all the various behaviors in this thread. It seems to focus on MS Office once it begins failing because I can still copy/paste in apps like Notepad.

My wife wants to return the computer and get another computer (or get another husband) thinking it will solve the problem. From the history of this issue, it may not be worth the effort to swap it out and risk the same result.

Thanks for the information, I will pass it on to the P/C specialist that I'm now working with. Not sure why some people have the problem and some users I talk don't experience it. Very strange. Microsoft doesn't seem to think they have a problem, not sure why.

I have a brand-new ACER desktop running Windows 11 and I've had this problem since purchasing it in July 2023. I am so frustrated with this problem that I'm considering switching to Apple As it would appear Microsoft is unable to resolve a glitch created of their own making.
