Greetings!!!

I had a problem with my dvd writer. I was not able to access. Then while
googling, i found a solution that deleting few registry entries upperfilters
and lowerfilters will solve the problem. but, when i delete entries and
restart, my keyoard and mouse stopped working.

Now finding solution for that, i found one reg file, if i will restore that,
things should work proper. But, as i have login password, and my keyboard
doesnt work, I am unable to login.
so my question is there anyway whereby i can bypass that login screen and
install that reg file. Or anyother way whereby i can restore my reg files.

I dont want to re-install windows, i have 100s of softwares and many
settings...

looking fwd for kind help

thnks & regds
