With reference to bean_man's statement above, I guess we can conclude that:-
No Password, No Issue.

So, TS, either you attempt to get a password, or you can simply close this topic. Cheers!

P.S. Don't give up hope though. There are "other" methods to settle your problem. Unfortunately, It is quite inconvenient to say it out loud. Forum Rules and Regulations MUST BE adhered.

Batch coding is not enough, really.

You need to know all the old OCX, DLL, EXE ... Entries in the Registry. And rest assure. An AV will have at least 50 of them. (not including self registered components/"Windows Automated Registering Behavioral Syndrome"... --> EXEs have a high tendency for this)

By the time you are done, you would have finished at least 10 cups of Nescafe. I wouldn't do that.

Cheers!
