After the anniversary update a couple years back, I had the following issues. I reverted my OS to pre-update, and issues went away. I couldn't update my OS after the reversion. Yesterday morning, my PC randomly automatically updated everything. Issues returned, same as a couple years back.
The odd thing about the issues is that they don't affect running programs. For example, gaming, coding, designing, browsing, etc etc are unaffected. I can have 20 heavy programs running no problem, and they work fine. The issues also don't begin until about 1 minute after the desktop loads, i.e. I can use my computer 100% normal for about a minute. This is the case whether I open programs during that minute, or do nothing. Note however, that navigation and right click functionality is still affected in many programs, as described below.
The issues are as follows:
- Dragging cursor on the desktop results in frozen blue square, or sometimes no blue square [blue square is anticipated result from dragging cursor on desktop, but it should respond quickly and disappear immediately after releasing mouse].
- Right click is very slow to load, and sometimes loads with no background/text.
- File navigation is VERY slow. Task manager, for example, is basically unusable, as I effectively can't click anything. I get the message "Working on it..." in my file navigation in the File Explorer, though it eventually works.
- hover effects on the icon navbar on bottom of screen are slow/frozen, and often transparent. "Hidden icons" on right side of that navbar usually don't load when the arrow is clicked (grey or transparent background with no icons loaded, instead, even though the icons are there (can click them still)).
I managed to fix the issue yesterday, after much effort, in an unexpected way. I used CCleaner registry cleaner, and everything was 100% afterwards. I thought I fixed it permanently, but sadly after turning computer on today, all issues are back, and registry cleaner no longer solves them.
My BiOS firmware is up to date, as is my CPU firmware, SSD firmware, and all drivers that I've been able to check. I ran memory diagnostics, and checked disk for corruption. I ran multiple virus scans, and ensured that the OS has all available updates. I've also disabled almost every single startup program.
Any thoughts are appreciated! I'd really prefer not to have to reinstall windows; getting everything set up again would take days.
