My operating system is Windows Vista with my PC being: Asus motherboard with 4GiG ram, dual 3GHz cpus and nvidia geeforce 9800GTX. Anyways, some time ago my PC started going REALLY slow and laggy and my gaming experience, both SP and MP games were suffering HARD! (Playing SC2 Beta, DA:O atm) THis became more and more painfull and i felt like destroying the whole thing with a hammer in rage after hours and hours running anti viruses and scratching my head. Then i found CCleaner, and some time after the problems were gone (Along with 6GIG of space on C: lol) Just wanted to personally thank you guys that made CCleaner, i definatly wont ever have a pc again without it. I have one weird problem left though... when my PC was messed up i couldnt update! I kept getting - think it was Error 80070026 something. Now AFTER using CCleaner removing all other problems the windows updater still wont work and has changed the error to error 800B0100. I was wondering if someone know what causes this? Again thanks alot!
