Vista Business 64 "Userinit logon application has stopped working" error after last Windows Update

Hi all,

I am getting a popup after I log on using my password  "Userinit logon application has stopped working" . When you click on the" close program" button you get a black screen. I have no access to any menus, ctrl alt del brings up the task manager.

The processes running are:

csrss.exe
taskeng.exe
taskmgr.exe
nvvsvc.exe
rundll32.exe
ielowutil.exe*32

I have tried:

1.Restart in safe mode (No luck)
2.Restore to prev point before the last Windows Update(After which the error started) using Vista DVD (Same error)
3. Swopping Hard drives (I use the EZ Backup option on my asus motherboard that keeps an exact copy of my hard drive. The other hard drive gives the same error )
4. The only other similar error I could find was http://support.microsoft.com/default.aspx/kb/929825/en-us , I accessed the registry via the start new task function and the entries referred to in the registry from the above solution are all there.
5. I have removed the hard drive and scanned it using another pc with Norton 360. The scan found no viruses or malware.

I do not want to reinstall vista and all my other programs as this will take me forever with all the online updates. And i am not sure this error will not happen again once I reach the same windows update.

Please give me some ideas.

Thanks

the start new task function try "explorer.exe" see if that pulls up the desktop. You might try "msconfig" to pull a list of startup applications and services and remove unknown/unneeded processes.

2. Disabling all non microsoft startup tasks and services. (Still get the same error)

can you run "eventvwr" in that same function field. look in the "application" and "system" logs and look for any errors that might be relevent, cut and paste the errors here too.

you can look up "event id's" (kind of like a check engine light code in a car, for windows) at www.eventid.net to help you diagnose.

try these tips

http://eventid.net/display.asp?eventid=1000&eventno=970&source=Userinit&phase=1

there is a "source" from which the event is flagged.... it should be labeled as "Src" in teh event viewer... is that "userinit.exe"? if so the above link applies to your situation.

The Source is "Application Error" Event ID 1000 Task Category(100)

Hi I have looked at http://eventid.net/display.asp?eventid=1000&eventno=970&source=Userinit&phase=1
The registry entries do not exist in Vista 64, and there were no scripts deployed to this PC as this is a home PC

Is there anything else I can Try?

boy this is a tough one. It appears that an application is crashing on bootup. If thats a windows application (assuming you set everything in msconfig's startup and services tab to off), is it possible to do a repair? Do you have the vista install cd?

PierellieCommented:
that exact error "Event ID 1000 Task Category(100)" is something that is logged when an application 'crashes'. Its more abundant in windows x64, with a 32bit app crashing

I've done a repair using the Vista cd "no errors found" I have also disabled all in msconfig with no luck

PierellieCommented:
can you check and make sure your drivers are all up to date? like video, chipset, sound, network. those kind of things? If this doesn't work, then i would think its a curruption with windows. The quickest way would be to do a re-install.

I found a workaround,
I ran the  "sfc /scannow" tool from the command propt to fix startup files: It gave the following message

"Windows Resource Protection found corrupt files but was unable to fix some of them."
Details in the CBS.log

The file that could not be repaired according to the log was userinit.exe in the System32 folder.

A quick search found 4 userinit files. I copied the one from the C:\Windows\SysWOW64 folder to the System32 folder.

I could not replace the existing userinit.exe file, so I named the new one userinit2.exe.

I changed the Registry [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion
\Winlogon] value to C:\WINDOWS\system32\userinit2.exe"

On restart all is working!

How do I replace the corrupt userinit.exe?? Access is denied. I would like to reset my registry entry to the original with the new file that works IE.

How do I delete userinit.exe and rename userinit2.exe to userinit.exe??

Thanks!

u know.... i've used that system file checker many times in the past... no idea why i didn't even suggest it... good job though! What I'd do is download a linux distro that is a bootable cd, boot into linux, and do your file work that way. Of course you'll probably want to make that registry chage back to original before you reboot and make the file changes. Good luck!
