When I reboot my system , it is using some old registry settings. Desktop resolution , background, and old file locations are adjusted to the same settings , irrespective of what I set it at shutdown . e.g if I change the resolution to 1600 X 1200 or 800 X 600 or any other setting , the next time I restart , it comes back to 1280 X 1024 ( my hardware is enough for all the resolutions ). Same about the files. If I cut and paste some file to a different directory, on next boot , the file exists in the old directory as well. But I am able to add new files to any folder.I suspect that some malware has modified some registry key . Please tell me if my guess is correct, and solution , if any.Thanks.1 person needs an answerI do too
