Windows used to allow way more than 10 days of restore points. When enabled, it'll fill up the storage quota assigned to restore points and delete the oldest one(s) when making a new one in low space scenarios. It has done that for ages now. I believe Windows will use 10% of the drive (max) for system restore points, though often I've seen that number lower by itself (I think when the disk is running out of free space? I don't know the mechanism that reduces the percentage).

Windows now doesn't let you restore restore points from over two months ago. That used to be longer, but they seem to have restricted the maximum retention time for some reason. I'm curious why, but I doubt they just arbitrarily decided to lower the retention time for shits and giggles.

Windows Me. Why bring up an operating model from 24 years ago if people got used to a different one now, with SR on by default?

60 days compared to the old 10-90 days doesn't sound too bad for most users, especially if it used to be "mostly 10 days". Probably every installer now creates a restore point quickly reaching the disk quota (used to be 10%).

Not sure why it's not configurable though. After all, it's local storage on my machine and my OS. So based on this alone a decision to enforce any deletion policy that the user can't control is MS being MS again.

Not including a [Keep off and don't ask again] option is one of the more infuriating things about modern software Android does this too)
