For years I have a strange problem with my file/folder context-menu in Windows 10 (my most recent build: 20H2, build 19042.804, but I already had this problem in Windows 7, and even in earlier Window versions).
I never knew what caused it, and kind of accepted it, but I got more and more annoyed, so I decided to ask help in the Windows tech forum a few days ago.
With some help (extensive problem solving in/with clean boot mode, with disabling/enabling Services and Startup items, via msconfig, System configuration), I was finally able to pin-point the problem.
This is the problem:
When you have a really long file/folder context-menu in Windows, that doesn't fit the screen, as I do, and you have to scroll down for the lowest items, then the text of these items is completely scrambled (SEE SCREENSHOT), as if more than 1 text is displayed at the same time on every line of the context-menu.
If the Windowblind service is DISabled (via clean boot, and consecutive normal boot, with the Windowblind service disabled), and all other services and startup items are ENabled then the lowest items of the context-menu are displayed completely normal. I tried all other combinations of Services and Startup items, but was not able to replicate the problem then. It only occurs with the Windowblinds service enabled.
So, I think this is a Windowblinds bug?
