Clipboard problems (can not copy/paste) in Windows 11

Okay, you're moving along, I noted a few things while you 'spoke'.

** Note: Items in [square brackets] are keystrokes (e.g. [command], [esc], [ctrl+alt+del]). Items in brackets and surrounded by quotes should be typed as seen.

1. It's good that hibernate and/or sleep are left out of the picture while Microsoft (we) diagnose the problem.
2. Are you part of a group? Or is this a personal PC (asked because of the MMC involvement).
3. Do you have 'special' software running? Anything you've installed to do stuff for you in the background? The clipboard object being used is trying to SetData, which is different than SetText, it suggests there is a lot more data?, an image?, a something that ISN'T text. Does anything come to mind?
4. Before leaving tonight, reboot into safe mode. It would be a good indicator if it's Windows System related or external poking in dependent on whether the clipboard is still an issue the next morning.
5. Something that had a large effect for me, but I haven't heard you mention, was clipboard history. Kim & I have ours off. Can you verify the same? [Win+V]
6. The underlying issue seems touch a lot of places. Tomorrow morning when you get in, repeat the steps below:
   1. Open Excel
      1. Type into at least three cells, going up, and going across (e.g. A1, A2, B1)
   2. Open REGULAR NOTEPAD. It must be the boring version of notepad (due to it's simplicity)
      • Copy the text from Excel into Notepad a ridiculous amount of times. You WANT the error. It has to be 'pickable'.
      • Did you get the 'Can't paste between applications yet'? Once you get it, do it ten more times!
   3. Open the Event Viewer => Applications => Windows Logs => Refresh SORTED BY TIME AND DATE
      1. If you sort by anything else, we'll be tracking stuff all the way back to your last clear.

What do you got?

Excellent suggestion, however, i reboot lets say 9am, the copy and paste function works perfect until i leave the office at 6pm.

when i get back in the morning the copy and paste function has failed and i need to reboot.

However, it is very consistent and has failed each time i come in so i will give this a go tomorrow.

i too get an excel error "the clipboard is in use" etc. copy and pasting a file doesn't work and right clicking explorer.exe to get to my pin list doesn't so there are a lot of signs.

i will give this a go and report back what i may or may not have found!

I'm sorry to hear that, but perhaps you can take the content and use it in the same manner... to investigate.

Reboot until that telltale moment that gives you the idea it has failed. For me, it was when I tried to open Windows Explorer would lose its address bar.

As soon as that happens, try copying pasting a bunch of times. My utmost success in finding the error after the internal crash was trying to copy from Excel into a different software.

After you force the error, open the Event Viewer, go into the Windows logs in the tree on the left and find the application logs… give it a moment to populate because there's a lot of data in there.  Find the red error icons, there should be a sea of them.  Look at the details of each one. Are they similar  Which CLSID can you see popping up the most?  You could reverse-search it through the root, but the first step is to find who is responsible.

I’ll help you where I can.

** A CLSID will look like a GUID, or a random string of number separated by hyphens, possibly enclosed in curly brackets

(e.g. {04CD1C44-3914-48E4-844E-F7D3519BC89A})

Glen, not sue why your post is in Russian? LOL

Hey Guys, I hope this helps.
