Windows 10: Explorer "Close all windows" completely stopped working

All of a sudden, when I have multiple File Explorer windows open, right clicking the "Close All Windows" button does nothing at all. This started about two weeks ago. I've run SFC full and it found no errors to speak of (I replaced a lock screen image that I hated, so the hash didn't match). I've also run Kasperski AV full and without exclusions, nothing non-trivial. I ran Kasperski's vulnerability scan, but the only thing it found was an out of date Firefox (which I fixed). Does anyone have any suggestions as to how to proceed, please? Thanks! Windows version: 64-bit Pro 1909

Step 1: I suggest you to run the Internet Explorer Performance troubleshooter.

Step 2: I suggest you to perform some of the troubleshooting steps from the link below link, Turn off add-ons, Reset Internet Explorer Settings, Open the page in Compatibility View etc. and check if it helps:

Windows Updated(16299.309).KB4088776 Restart is required to complete.

Hi dalchina. Good news, I followed your suggestion and reinstalled the update and now it appears as "installed correctly" *Biggrin Maybe it was not necessary to run the Windows Update Troubleshooter or maybe if necessary. But using it I do not think it could have worsened something. The installation was very fast, unlike the first time it showed step 1 and step 2 completed.

Thanks for the suggestions and for the time to respond Best regards.


And thanks for the tip of that program, I'll have it on my list.
