Admin rights lost, now only limited rights. Won't let me do anything - keeps telling me I don't have permission or see your administrator. User accounts only has me as limited a/c & Pick A Task only shows this. Set up 3yrs a go with me as administrator. Worked ok until now. Anyone got the answer?
As long as your are in windows, as limited user, you should not be able to change this. If you could then there is no point in the whole security scheme.
However there is nothing that prevents you from booting from something else, mounting the harddisk which contains the windows files and changing the rights. There are many tools for this, e.g. locksmith on ERD, or my personal favourite, this disc.
Use either to:
If you are a local user you can use the Windows XP recovery disk to restore your machine. Otherwise your only option is to wipe the disk and start again.
By definition, limited users can't overrule or become administrative users, otherwise there wouldn't be any security added by making some users limited.
