SSD size 128GB
Windows 10: let's go and use 40 fucking GB for windows.old.

Like WTF, use 1/3 of my ducking storage for "I don't trust updating myself so here's a massive restore point"

Fuck you windows.

To be fair, I don't trust windows update either.

You do know you can remove it, right?

@Root I don't trust it either. But system restores never use to be that big. This thing is a complete copy of c:/ so It can do a hard rollback.

@monkeyboy yes, what I would like to
Do is put it on my second drive though 🤔the one with 1TB of space

@C0D4 Do what makes you feel comfortable, but I've never had to use the old directory through hundreds of upgrades. Alternatively, larger SSD drives are inexpensive these days. Inexpensive is always relative, of course.

Up until a recent change windows basically didn't know if you had enough space to upgrade (That is, for major upgrades, not just your usual patch), so they _had_ to store a working copy somehow, otherwise they wouldn't be able to roll back. Now they just force you to have at least x gb free before upgrading (on new installations only)
They probably still save a copy tho.. For reasons. But they usually get cleaned up automatically after time x..

@Kimmax I'm not up to that version yet. I've only Just unlocked dark mode on this laptop 😅

I get why they have it, it just seems like massive overkill to actually create a complete restore m. Unless even MS don't trust their update processes and expect my data to be destroyed in the process.

@C0D4 well yeah, there always could be something going wrong while updating. It's essentially just a replacement of files with new versions and probably a registry patch afterwards, so it definitely isn't that dumb to store a copy. Sure, you could store a delta or something, but they probably know, or don't know, why they are doing this. It's probably the procedure that was the easiest to implement (think about this being engineered a few years back for different hardware) and wasn't replaced yet 🤷🏻‍♀️
Simple systems are hard to break.. They could hide it better and get rid of it immediately after the first successful boot, but I think keeping it just in case isn't that bad of an idea, given the resources are there most of the time

@C0D4 (you will only get the new upgrade routine for a fresh install, upgrading will not enable this for old installations)

@Kimmax so tldr; it’s safe to trash??

@broseph yes, if your update boots without issue.

@C0D4 sweeeeet

@broseph what @irene said. Disk cleanup will take of other update remainings too

@Epstein-guy I use windows insider skip ahead branch. So i usually update the windows around 3 times per month. And every time I delete the windows.old.

This is going for more than 2.5 years. I have not need to rollback using windows.old in those 2.5 years.
