There is a program called "System Restore" that takes the computer software back to an earlier day without loosing any data or bookmarks etc

Programs > Accessories > System Tools > System Restore

it will suggest the most recent entry point...or you can change it.

Yes, I’m computer literate about System Restore and many other things, but this one glitch was a new one on me.
