Solved System Volume Information files filling hard drive

I recently replaced my hard disk. The C: drive on the old disk was 350GB with 100GB free when I replaced it. I've made this partition 500GB and now there's only 20GB left.

I'm finding several files created just this month from 65Kb to 34.7GB in size. They are not all restore points from what I can tell either. I only have 1 restore point for each day over the past week, but 2 and 3 files on some days. The System Volume Information folder is now 311.8 GB in size.

Is there a way to get rid of some without clearing the restore points?

Could the System Restore configuration just be corrupted?

How can I fix this?

Create a new restore point then change the size allocated to system restore points.
By default Vista uses 15% of your disc space
Then delete old restore points
Try something like this in CMD as Administrator

vssadmin Resize ShadowStorage /For=C: /On=C: /Maxsize=10GB

I should have said you can set it to any amount you want and to find out what it is now try the following in CMD as administrator

vssadmin list shadowstorage

The vssadmin command needs to be run from a Elevated Command Prompt.

I was having some problems so I restored to an earlier restore point. During that, Windows didn't find an operating system. I finally got it booted and the restore finished but things were not loading. It wouldn't reboot again either so I forced it to power down and booted from the last known good configuration, but I'm having the same problem. I'm writing this response on my phone.

And now the reboot required a Startup Repair. It claimed the partition table does not have a valid System Partition. This is a brand new disk! That's the same reason I replaced it!

I managed to get it to boot to the administrator profile. The shadow storage size was unbounded. I set it to 100GB. My free space is now 334GB.

Great, so it appears to be working again. One thing I noticed when getting to Startup Repair and command prompt startup menus is that it says "Windows Vista Home Premium (recovered)". Does anyone know how to remove the "recovered" from that. It's one thing to tell me it was recovered, but after that, it's just WVHP again. I don't need to be told forever. I found a couple of entries in the Registry, but they are not editable.
