Hi, hope you can help. I'm not able to open task manager in any way like rt clicking on task bar, alt ctrl dele or ctrl shft esc, a message comes saying that its been disabled by administrator which is me. I only use the PC its XP home edition, how can it work again or be enabled? Thanks for help, bye.

You can try this if you have admin priviledges:

Now try this... start your account with user name "administrator" and no password
