My Sony Vaio, windows vista home premium will no longer open windows. I can not access windows through the safe modes, I can only access the command prompt through the repair my computer option, using a recovery vista dvd. Which isn't a full recovery disc just a bootable one I bought online. In the command prompt, I typed regedit.exe and viewed part of the registry as follows:
- WINDOWS NT
- SHELL - its states "cmd.exe /k start cmd.exe"
Sony have confirmed to me that the shell should state "explorer.exe", I have tried amending the value however after exit and rebooting the laptop this value reverts back to "cmd.exe /k start cmd.exe". If I can't amend the shell value then a full system recovery will be the only option they say they can advise me with.
Why can't I rename the shell? Is it because the explorer.exe file has been corrupted or deleted? Do I have a virus? If I do have a virus and attempt to restore my laptop will that solve the problem?
Please see link above for previous posts.
Also I did look at the preparation guide before posting, although I am not sure how I do the following without being able to access windows?
1. Back up Data - Vista Complete PC Backup - Is this the option I should pick because my OP is Vista? But I can't access Windows Start - All Programs - Maintenance - Back up and Restore Center.
5. Enable A Firewall - I can't access the control panel
6. D/L & Run DDS to create log of programs running on pc - Can I download this on another working computer and use it to run the DDS tool on my laptop when I can't access windows?
However I was able to copy the C: drive and user area from my laptop by using the recovery disc, repair my computer option, when selecting the upload new drivers which gave me limited access to my computer. It only let me see the driver set up or installation type files (can't remember exact wording) so I copied the whole C drive and user folder to a WD hard drive. Was that a mistake to do that? Especially if I may have a virus?
I hope that all makes sense! Any advice would be greatly appreciated.
Thanks for your help
p.s. After reading some of the self-help guides, which explained how virus' can infect your computer. I know the following were running on my machine.
Actual Spy - downloaded a couple of months ago.
Registry Checker/cleaner - Over 6 months ago, I can't quite remember the name - Registry Mechanic or something similiar, it was a trial, I don't remember letting it fix anything and I did not purchase it.
Watched TV online - I was asked to download something because I did not have the correct codec or something, I think I clicked on it by mistake! This was the last thing I did on the computer.
Shutdown incorrectly - The next time I tried to log on which was a few days later there had been a powercut, the switch tripped so my computer was shut down incorrectly when it was in sleep mode.
