Encouraged: Clean up unwanted software

Keeping third party software down to a minimum helps reduce potential complications. Consider removing software previously installed, that is no longer required.

Third party antivirus also causes complications compared to the native Windows Security.

If you suspect adware or potentially unwanted software installed:
