Over the past couple of months I have tried every PowerShell script / scannow and driver update that I could find, tried many suggested control panel settings, installed and ran MANY antivirus programs, replaced batteries, left batteries out for an evening, tried multiple wireless mouses, used different USB ports, and yes… even allowed a full MS software upgrade. Howdy, and before I get singed for not searching and reviewing posts please know that I have. Allow both processes to complete and then reboot.

Then type ‘Dism /Online /Cleanup-Image /RestoreHealth’ and hit Enter. In the same CMD window as above, type ‘Dism /Online /Cleanup-Image /StartComponentCleanup’ and hit Enter. If you see a message that says ‘Windows Resource Protection found corrupt files but was unable to fix some of them.’ then you will need to manually fix the issue. This is okay too as it shows Windows is working (mostly) okay. With any luck, you will see a message that says ‘Windows Resource Protection found corrupt files and successfully repaired them.’ You may see ‘Windows Resource Protection did not find any integrity violations’. If the scan finds any issues, it will automatically repair them. The scan may take a while but will look after itself. Finally, when the black box appears, type ‘sfc /scannow’ and hit Enter. Type ‘cmd’ into the box and check the box to create the task with administrative privileges. Right click the Windows Task bar and select Task Manager. The SFC checks all Windows files and makes any repairs if it finds issues. It is a self-contained test that is run from the command line. Performing a System File Check (SFC) scan can help detect any issues with Windows that could be causing your left mouse button to not work.
