Windows offers you the feature of using system protection on drives other than C. You open 'System Properties' and then go to the 'System Protection' tab, you have the option of enabling it and creating restore points on every drive installed.
The problem is that you can't restore them. Upon launching System Restore, windows will show only the restore points in the C drive, and if you have none there, it will tell you no restore point is present in the system drive.
Coming back a few years later to give what I hope to be a definitive answer to this question, since I was able to figure out how windows handles this but didn't come back to post anything about it.
Simply put, Windows allows you to use System Settings to add restore points to new drives, but any method to rollback to a restore point will only see those in the C: drive, and there's no changing that.
In short, creating restore points in drives other than C: will only eat up your space, as Microsoft never implemented the functionality needed to restore those.
By the way, I've been using Windows for more than 2 decades in my experienceand restore points will sometimes be very effective when dealing with two issues:
I don't remember it ever reverting a situation where the system was unbootable, though. Restore points might've been useful back in the days, when you had little storage available and it was slow and expensive. Nowadays it mostly doesn't make sense. If you use a tool like Macrium Backup paired with a 1TB drive you can backup your system for months in a row without needing more space (depending on your use cases and backup configuration).
Synthetic full backups, for example, may last you 3 months on a 1TB drive (maybe even more), time during which you can roll your system back to any day of these three months and when that happend you'll boot to your system exacly like it was that day.
So, in short, leave restore points alone, there's no point in using them in 2024.
