First, did you ever turn System Restore on? It defaults to OFF in 10.
Second, if the answer to the above is yes, then deactivate your antivirus and try again. Note that Windows 10 has a pretty good antivirus (MSE) builtin to Defender.
Uninstalled Office by mistake. I need the files.
Tried Sys Restore but error says something like "a file could not be accessed and sys res did not work turn off anti-virus".
Tried with anti-virus off (Avast). No go.
