"Microsoft's new Windows 11 recovery tool is the ultimate Undo button - how to enable it
After a CrowdStrike update caused millions of Windows PCs worldwide to crash in July 2024, Microsoft announced the Windows Resiliency Initiative. The new Point-in-time Restore feature is a key part of that."

"ZDNET's key takeaways:

•     The Point-in-time Restore feature is now available for all Windows editions.
•     It takes daily snapshots of the system state to help recover from a serious problem.
•     If your system drive is 200 GB or larger, the feature is on by default."

"This tool solves a problem as old as the PC itself. "I don't understand. It was working fine yesterday. Then I did [some seemingly innocuous thing] and now it's crashing." About that time, you desperately wish your keyboard had an Undo Today button.

That's Point-in-time Restore. It's one of those rare Microsoft features whose name perfectly describes its function. It rolls back your PC to a time when it was working properly, undoing everything that happened between then and now. Aside from ensuring that the feature is turned on, there's nothing else you have to do."
