I have a problem with WinXP Professional. One day I shut it down using the power switch on the box, as I have done before, and the hext time I reboot, Spbot S&D went nuts. I refused all the file authorizations it wanted ok'd, and now WinXP Pro is down.

I have a backup disk, but it's apparently not enough. When I tried reinstalling it I got an error code "Error Code 0x8007007f".
It also said the following files could not be opened-
c:windows\system\catsrv.dll
rundll32.exe
RUNDLL32.EXE
regsvr32.exe
mshta.exe
fixmapi.exe
odbcconf.exe
mstinit.exe
unregmp2.exe
wmpstub.exe
wmplayer.exe
grpconv.exe
c:windows\system\directdb.dll
c:windows\system32\inetcomm.dll
c: program files\outlook express\msoe.dll
setup50.exe
c:windows\system\wab32.dll.

Desktop links don't work. I can point them right to the specific file to use, and it sets ALL links to run that program. In this case I tried to reset the link for Notepad, and now all desktop links use notepad to opn the links but not the programs the links are for.

A good portion of .exe's are not runable. I am able to run some non-Microsoft programs like Firefox and Thunderbird, but OE 6 won't run. Can't do a scan disk unless I go into START, then RUN, then CMD, then BROWSE where I have CMD located. Tried chkdsk/f, but won't run with windows open (?) and when I schedule it to run on next bootup, it doesn't.

I'm thinking that the memory on the HD (40 GB Samsung) is to blame. I'm not a computer geek like I used to be, so I'm just guessing. The HD needed replaced anyhow, so I have a replacement HD (80 GB) with WinXP Pro installed ordered, but it's looking at 2-3 weeks before I get it. Maybe longer. Right now I need to do what I can to fix this until that replacement HD gets here.

I have tried downloads to fix it, but once downloaded it doesn't even recognize the .exe's.

Any ideas?

Hi and Welcome to PCHF.


Shutting down from a fully booted computer using the power button can and does damage files. Not a good practice.


Because there were no previous incidents like this-- does not mean there were no errors there-- Windows will tolerate quite a bit... but one day-- This happens-- and then you cannot boot correctly due to a damaged registry.
In this case --I am still trying to find that exact error.
"Error Code 0x8007007f".There are many hundreds-- if not thousands of Stop Error Codes.
You say you tried the reinstall? Repair reinstall I presume??

Have you tried booting into "Safe Mode" ?

Workaround for error code 0x8007007f or error code 0x8007007e

might be caused by a sevice pack
To work around this problem, uninstall the service pack that you installed. Then, reinstall the service pack.

full link also welcome to PCHF I just noticed your new here
You may receive error code 0x80004005 or other error codes when you try to start a Windows XP-based computer

Nice work Matt-- Thanks
@ CactusJack? use the start button man-- it allows windows to kind of "brace itself" for shutdown-- greatly reducing errors.
You'll still get em-- but not as much...

You might want to give this a whirl -- I use it weekly keeps it tuned right up. Registry Mechanic - Registry Cleaner

I used to use both. Now, I use just the start button. Sometimes that hangs up which is why I started using the blue button.

I've started in safe mode, no different. Tried reinstalling, tried recovery, tried fixing, all no good.
