Windows 11 can now undo a bad update on its own. It needs 200GB of drive to do it automatically

Windows 11's July 2026 update rolls out Point-in-Time Restore broadly — a recovery feature that automatically snapshots your entire OS volume and can roll a bad update or driver back in minutes instead of the hours a full reinstall used to take. It's a real upgrade over the old System Restore most people gave up trusting years ago. There's one catch worth knowing before you assume it's protecting you.

Why this isn't the old System Restore

Classic System Restore tracked registry and system file changes — useful in theory, unreliable in practice, and the reason most people learned to distrust it. Point-in-Time Restore works differently: it takes full Volume Shadow Copy Service (VSS) snapshots of the entire OS volume at a set interval, which is a genuinely more complete rollback mechanism, closer to a real backup than a change log.

The 200GB catch

Only devices with a 200GB or larger OS volume get this switched on automatically. Smaller drives — common on budget laptops and older systems — default to off, though you can still enable it manually in Settings. If you're on a smaller drive and assumed this was protecting you automatically after installing the July update, it isn't unless you turned it on yourself.

What it actually protects against, and what it doesn't

This is built for the specific failure mode of a bad update or driver breaking your system — the 72-hour retention window covers exactly that use case, since you'd typically notice something's wrong within a few days. It is not a substitute for a real backup: three days of retention won't help you recover a file you deleted last month, and it does nothing to protect against drive failure or theft, since the snapshots live on the same physical disk they're protecting.

The honest read: this closes a real gap for the most common recovery scenario — Windows Update breaking something — for anyone with a reasonably modern, reasonably large drive. It doesn't change whether you still need an actual backup strategy for anything that matters long-term.
