Trouble:

It is extremely annoying to get stuck at the welcome screen of windows Xp. One of our readers submitted such problem, that Windows Xp hangs at welcome screen. This happens mainly due to some problem with one of the system files of windows Xp. The file is MUP.sys.

What is MUP.sys?

The process Multiple UNC(Uniform Naming Convention) Provider driver belongs to the software Microsoft® Windows® Operating System by Microsoft Corporation. This is Microsoft system file which is needed at the time of startup.

 

Why computer hangs at welcome screen?

When there is something wrong with the MUP.sys the computer hangs at welcome screen. Which maybe due to a hardware problem or a driver problem or may also be due to a virus has corrupted MUP.sys .

 

Let us see how to fix it up.

Fix:

Generally there can be two ways to fix this problem

Fix1 : If MUP.sys has been corrupted due to a virus action, then try to boot your computer in Safe mode and run a full system virus scan with your anti-virus software, this may fix the problem. The system will boot in safe mode only if its not a major damage to the file. If the system is not booting in safe mode, then refer to Fix2.

 

Fix2 : In case the system refuses to boot up at all, then it is recommended to run a repair setup of windows Xp. To run repair setup, boot the computer with Windows Xp bootable CD and on installation screen, press R for repair setup. For detailed steps see this link.

 

Tip : Run disk-scan once a month and virus scan once a week to avoid file corruption problems. Keep the anti-virus definitions updated for defense against virus attacks.

Yes. I had this problem. But I fix it by restoring the system to an early state by using system restore point. After that it doesn’t hangs at the welcome screen. Whether it is a better option?

I had identical problem (XP SP2 freering on the Welcome Screen) – I run UBCD, did a Disk Check, it fixed some indexing error and the problem disappeared. Before the Disk Check I run a full computer check for viruses (with a Avira program from the same UBCD) but found no viruses.

My Desktop Acer with Windows 7 will not Boot. We have been having trouble with it crashing for some time, usually when my wife is on Facebook playing Words with Friends. It has also happened when I have been working with the iTunes files. It would freeze with a lot of scratchy lines across the screen and could only be started again by unplugging it. This same thing happened recently except when we plugged it back in and it started to reboot it stops, just as the little dots that swim around and make up the windows logo start up. The screen goes blank and then opens a window that gives us options to scan and repair. Choosing that option, the computer works on it for a while and then says that a repair cannot be completed. It also gives the option to restore. I tried that several times and that didn’t work either. The log shows that there is one problem that cannot be identified. All I can do at this point is to choose Cancel and the computer shuts off. I am presently at work so I do not have immediate access to my home computer. Any advice?
