I had to remove Windows 10 due to their anniversary update.
The Start button was no longer clickable. You could not right click on any program button on the taskbar.
Prior to this I was not able to get to several websites I could before. I tried all the fixes offered but the only one that worked was a complete format and install of Windows 10. A temporary fix. Temporary!
A Windows refresh would remove all my own programs and leave theirs that were the cause of the issue (Cortana)....! After 3 times of doing a clean reinstall and having the issue come back I went back to Windows 7. A KNOWN issue too since the beta and Microsoft will never ever fix the issue.
Add to this the change in the look of Windows like the Start menu.
Very angry at that outsourced Microsoft CEO and those like him who think THEY own the software and my hardware.
Hours and hours wasted because of their integrating Cortana so they can spy on you.
