I removed all the updates from April 1st, 2025 on my computer that I could. I still have this issue even after removing KB5055518, the mentioned fix. Two updates remain that I cannot remove:
Tried removing KB5051974 - kept getting error when uninstalling. The message was "An error occurred. Not all of the updates were successfully uninstalled."
servicing stack 10.0.19041.5676 - wouldn't let me uninstall
The next updates for MS were installed on 3/15/25 and Adobe on 3/23/25. I certainly would have seen this issue between 3/23/25 and 4/1 (actually more like 4/6 or 7 when the offending updates occurred).
Either those updates I can't remove note above are causing my problem OR I must have to now turn this, right click file feature, on somewhere.
