HELP.

I had 2 csrss.exe files running on my Dell PC and read that was a bad thing and could be a virus.

So I did a search on my C drive to see where these files were located & 5 came back. 

I kept one in C:/Windows without changing it, but changed the other 4 to csrss.exe1 (so I wouldn't delete the files, but also it should stop the files from running on windows).

Then I restarted the computer and now windows won't open, giving me a c000021a error.  I believe the issue is the csrss.exe1 file that was located in C:/Windows/System32.  I'm hoping all that I need to do is get to a command prompt, change to the System32 director and rename the file back to .exe

The problem is I have no idea how to get to the command prompt before Windows tries to load and gives me the blue screen of death error. 

- Does anyone know how to get to the command prompt right when the PC starts?
- Do you know if my assumption is correct that once I rename the file in the System32 folder that windows should start correctly?

Thanks!
