Troubleshoot What is going on?

Current list of issues

mouse won't connect and programs disappeared

Steps taken, but have been unsuccessful?

uninstalled DefenderUI, tried a different usb port.

So today on both of my computers, some programs disappeared from start menu and desktop shortcuts, my mouse doesn't connect, I kept getting ""your admin blocked this action" warnings in action center. Already set DefenderUI to default and uninstalled it, but still not fixed. Anyone having problems with windows today?

MS defender updated caused ASR to delete files.....
not sure why your mouse is affected.... but for sure .lnk (shortcut filese were removed by a dodgy defender signature

update your signatures....
Set "block win32 API calls from office Macros" ASR rule to audit for now.....
mount a recent backup and restore your shortcuts manually or robocopy by extension

maybe try to uninstall/reinstall the latest driver?

It should light up and work without the driver.
I'll have to try that later.

Yeah, the ASR issue broke my mouse too... to fix it I restarted the computer and unplugged and replugged the mouse once Windows came up.

Already did that, mouse still dead even in other usb ports.

Do you have another mouse you can try?
Do other USB devices work?
Check in device manager if any exclamation marks ..

Maybe try dism / SFC scans

DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth
sfc /scannow

I turned off the PSU and waited a while, the mouse is now back alive.

 

[kC77]

if in doubt turn it off & on again good news your back on
