Right-click very slow to display the context menu

Question

Hello everyone,

I'm coming to the forum to share a problem that I can't seem to solve and that is quite frustrating:

When I right-click on a file, the hourglass replaces my mouse and I have to wait a good 10 seconds before the context menu opens. I opened the Task Manager to check which application might be the cause, and during the right-click, the executable "WMI Provider Host.exe" spikes in CPU usage (up to about 17% of the processor), then as soon as the context menu appears, it drops back to 0%.

Conclusion: I think this executable is the cause of my problem but I don't know what to do :(

Thank you for your help

Best regards.

P.S.: Everything works fine with folders; the context menu opens immediately upon right-clicking.

Well, I'm answering myself because I found the solution. Actually, if the item "Send to Bluetooth device" in the context menu is buggy, I opened CCleaner, then in the "Tools" section, under the "Context Menu" tab, I disabled "BSAppShlEst.dll" and that resolved the issue!

Hello,

for me, it's impossible to find the source of the problem with CCleaner.
So, for those who might be interested:
there's the ShellExView software that resolves this problem quite a bit: you just need to test the displayed .dlls in the software in blocks.
I say by blocks, because otherwise it's tedious: you can then narrow down the search: consider it as a filtering/trial technique.

Important: to check the result of enabling or disabling a file, remember to go to menu>options>reboot explorer (or Ctrl+E), otherwise the changes won’t be visible.

For my part, it was the access to the graphics card through the context menu that was slowing down the click.

Good luck to you.

Thank you, Andy!! Great method to find the issue.

In my case, the problem was a bit different: I had to wait about 6 seconds when I right-clicked, but not on the files/folders, only in the blank areas of the folders (like to do "paste here"). By fiddling around with ShellExView, I found that the source of the problem was "the desktop context menu class"... I’m not entirely sure what that is, but there you go!

Thanks again!
