Backup and SP1 Problems

#1
Folks I got a clean Win 7 install. I have 2 problems, first it seems windows kept some data in windows.old folder. Do those files have impact on my system? If yes should I format all over again and re-do all the steps?
Assuming it has no impact I have another problem, windows complain it cannot create backups because of problems on VSS and SPP are those problems related?
I was also unable to install SP1. I'm not sure if those situations are related. Should I format all over again?
