I changed the password using "net user aditya aditya^Aaditya". But the problem is now Vista is not accepting this password. When I type '^', nothing appears, but when I enter it twice, then 2 characters appear, I erase one of them and then type the rest of the password. But it is not accpeting this password. I dont have password reset disk also. Please help me. I have a very critical data.
