Restore Points And Vss Event Id Errors

My restore points keep disappearing on my computer. It doesn't matter if it is manually or Windows generated, but after a day or two at the most, there aren't any restore points on my computer. This even occurs after I manually allocate with the vssadmin resize shadowstorage /On=C: /For=C: /Maxsize=120G command.

I am running Windows 7, have taken all the precautions of checking for viruses, malware and spyware as I used Malwarebytes Anti-Malware, Super Anti Spyware, AVAST and Adlice Anti Rogue Killer programs on my computer.

I have filtered out the Event IDs in the Event Viewer and found three errors that appear to be related but I don't know how to interpret them, 22, 8193 and 12305. I've attached copies of them.

Any help would be appreciated. Thanks in advance.

 

Could you be short of space on your C drive? How big is it and how much free space does it have?

 

Have a look here.

No, as I have a 750 Gig HD and am only using 200 Gig currently

 

Thanks, but I have it currently set to 130 Gig for restore points.

 

Not a XP/Win7 dual boot?

 

No it isn't
