Need Serious Help: How To Record Video of What is Done on my PC?

I suggest the following simple steps:

1. Set the autosave options in MS Office to a low value say 5 minutes.

3. Install Macrium Reflect Free and configure it to do a daily incremental system backup

You should be well covered if you do the above to protect your key files.
