Hello Bmays, welcome to the forum.
Windows sets restore points every 24 hours or so your computer is on. You can also set System Restore points manually, something you should do before you do any major tinkering with your system (just open
System Restore, click
Create A Restore Point, and follow the prompts).
Theoretically, you should be able to roll back to any restore point. If you keep XP fully patched and don't engage in unsafe computing practices, the operating system is remarkably robust. And, no, the partitions shouldn't faze System Restore.
So, why is your System Restore failing? Here are some possibilities in my opinion:
1. System Restore files have become corrupted. To fix this, you'll need to switch System Restore off, reboot, then switch it back on again. Unfortunately, you'll lose all your existing restore points in the process, but it should get System Restore back in working order once more:
- Right-click My Computer and choose Properties to open the System Properties dialog.
- Click the System Restore tab.
- Tick Turn Off System Restore On All Drives, click OK and then reboot.
- Open the System Properties dialog once more, untick the box you just ticked, and off you go.
2. System Restore doesn't have enough space to work.
3. You have a Spyware or virus infection.
So what i suggest you do run a full updated anti-virus scan and full updated Malwarebytes scan.
Hope this will end your problem. If not please post your scan result so we can go more deeper in this problem. Thanks
