how to roll back windows?

Question

i can only roll back 4 days why not a month i dont get it helpppppppp please

Answer 1

xp is set up on a month by month time table. so every 30/31 days it resets to zero. this saves hard disk space by writing over the previous 30/31 days of set points. unfortunately it does a simple wipe of the previous 30/31 days before it starts the write over.

Answer 2

well it depends on how many times does your windows system check (it creates checkpoints), if you wanted a month rollback, better create your own checkpoint in the system restore window, it will work!
