Previous Versions tab in Windows has no shadow copy snapshots.
Shadowcopy is disabled by default on the desktop.
Use task scheduler to run the following command at a desired schedule:
wmic shadowcopy call create Volume='C:\'
Each time this is run it will create a shadowcopy snapshot allowing you to restore accidentally deleted or overwritten files.
You can use this interactive helper script to automatically create a scheduled task that will run the above command every day at 1pm.
