Windows 7: Why is W7 Saying Not Enough Backup Space?

Windows 7 Home Premium 64 bit
Windows 7 backup storage space problem 0x81000033 resolution

I had the same problem and nothing that I did fixed the problem. I followed all of Microsoft's fixes to no avail. Luckily I found a website that had the exact fix, links to the free software you will need and detailed instructions (including screen shots). I followed the instructions and now my backup works flawlessly. The link to the website is below. Good luck!

Yes Lexie164 the system reserved should have always defaulted to a size greater than 100MB in the first place. If you want a system reserved when doing a clean install setting it to around 200MB is a good idea.

Your link to the use of PW to extend should be useful to others. But moving your OS partition like this is not without risk. I'm a bit surprised that a System Repair wasn't required after the move but apparently not.
