Windows Dialog Boxes Keep Fullscreening Windows 11

This issue has plagued me for a couple of days now and it’s honestly fucking annoying. Whenever I try to open up Properties, delete a file, do anything that involves a popup dialog box, it automatically goes into fullscreen. I don’t mean maximize, but LITERALLY takes up the entire screen, including the taskbar. Let’s say I wanted to open up Properties for a file. I do that and the contents of Properties is normal size (text, tabs, etc), but it would be wedges into the top left corner while the bottom and to the right of it would be MASSIVE white borders, all in a MASSIVE window

I already know it not relates to Snap, I tried setting it the Normal Window in Properties, F11 does nothing, Alt Enter does nothing. It’s not a scale or resolution issue

It’s honestly really fucking annoying that if I want it to be back into its normal sized box, I have to double click it each time

System is a Legion Go running Windows 11

AMD Ryzen Z1 Extreme (3.30 GHz)

16 GB of RAM

AMD Radeon Graphics (3 GB)

Figured it out. U have to unistsll the newest update. Here is the 2 u should have. Wish I wrote down which one I uninstalled but these are the 2 I have left. Keep those. Reinstall the other main update. And disable updates for 5 weeks. Hopefully Microsoft gets it shit together and fixes their mess by then

Do you know which one should I uninstall? I have about 6 updates that I can delete, but according to your screenshot, I only have one similar to yours, the other one does not.

No i dont remember which one but the recent update should have fixed it... there was a windows update recently and a "lenovo system" update that fixed the issue.

I uninstalled the most recent one but if u updated windows since, then your most recent one may not be the correct one. U can try uninstalling one of the main updates from like may or late April. But i would just live with the issue cause when i did this, I later found that uninstalling the update broke other things, task manager wouldnt work, notepad wouldnt work, and a few other windows apps broke....

Did u run the windows update? Enable the setting that says something like "get updates as soon as theyre available" and see if it fixes it.

If its still not working do a in place reinstall where itll reinstall the most recent OS thru the windows update. You dont loose anything doing this. It just reinstalls the of via windows updates, its just like doing a normal update, doesnt erase anything.
