Please note that nothing works under old account and this forced me to create another account but logging on to new account does not give me the liberty to access my old data. Regarding solution, please also note that I tried everything whatever was suggested to me but unfortunately nothing worked. Honestly speaking nothing can be done, I can't touch anything means if I click any program icon, the OPEN WITH windows pops up. I can't back up Registry, Log on to Internet or Open any program etc.
As far as the feedback is concerned, please note that I replied to the message I received. After that nobody contacted me in follow up to resolve this issue, therefore I surrendered and zipped up my mouth for a while. But later I realized that this is not a proper approach, people learn at this forum and help others. Therefore I should explain my problem once again and may be I get a good news from someone. Please help me if you can in resolving this issue. Regards and thanks.
