How I solved Mup.sys problem

[PinkShell]

Hi friends,

I am using Windows XP as my operating system and everything was working fine few days ago but today when i try to go into safe mode at the load screen it get freeze at system32\drivers\mup.sys.When i asked my friend about the same he told me that try to disable mup.sys hope it works, i try to do that too, but still facing same issue and at the same time please provide me some information about it too.

Normally Mup.sys is located in the folder C:\Windows\System32\drivers and it's file size on Windows Xp is 107,904 bytes, 104,064 bytes, 105,344 bytes. If you are planning to start or stop from servicing then you can goto Control Panel and make changes over there and normally this program is not visible for this you need to have a check for it very carefully .

I was also getting Mup.sys problem on my clients computer at his place things where getting freeze during the subsequent initialization, then i try to start his computer in safe mode and then click on Start and type cmd in Run option and press enter and after that type the following C:\Windows\system32\restore\rstrui.exe to run System Restore and hope that going back a few days where you was not facing any issue.

1. Insert Windows XP bootable Cd in the Cd Rom and restart your computer.
   
   
2. Press R at the welcome screen to start the Recovery Console
   
   
3. Now type the Administrator password and if you have not set any administrator password then just press enter.
   
   
4. At the Recovery Console command prompt, type the following lines, pressing ENTER after you type each line:
   
   md tmp
   copy c:\windows\system32\config\system c:\windows\tmp\system.bak
   copy c:\windows\system32\config\software c:\windows\tmp\software.bak
   copy c:\windows\system32\config\sam c:\windows\tmp\sam.bak
   copy c:\windows\system32\config\security c:\windows\tmp\security.bak
