Recently, we discovered a few computers not being able to copy and paste from folders locally and over a network share. We can copy and paste in programs like word excel, such as the text. Can drag and drop okay though. Keyboard shortcuts don't work as well. This is effecting files and folders mostly.
Few things we tried so far that does not work either:
Logged in as a local administrator
Uninstalled Antivirus
Disable GPO and Local Sec Policy
Internet explorer cleared cached
