Error Code 0X8007002

My Acer 4220 Vista Home Basic doesn't allow me to access my Administrator
Account. It displays Logon service failed. Iam also getting a request to
activate my windows product number. I've tried lots of times to remedy this
but to no avail. It now tells me the version of windows I now have is
counterfeit. What do I do now? Please help me.

Prepare recovery disk->'Windows Vista Recovery Disc Download —
The NeoSmart Files'
(http://neosmart.net/blog/2008/window...disc-download/)
boot it and

Choose language>>repair computer>>system restore

and back to any checkpoint
