Most UserInit problems are a result of virii/spyware....

 would actually do a few things first........Install and update Super Anti Spyware and reboot to Safe Mode. Then do a full scan, and see what it finds. Or, if you prefer, scan with MalwareBytes....

SUPERAntiSpyware.com - AntiAdware, AntiSpyware, AntiMalware!
http://www.superantispyware.com/
One of the best on the market (and it is free, although you can upgrade and get Real Time Protection). Under the Options, go to Scanning Control> and make sure it is set to the following.....

Terminate memory threats - checked
Ignore non executable files - unchecked
Scan only known file types - unchecked

Manual Definitions Download....

MalwareBytes

Can also use Combofix. (stolen from rpggamergirl's postings...)  :)

Here's the instructions, if it doesn't run at first, then redownload and rename before saving to your desktop.
Please download ComboFix by sUBs:
http://download.bleepingcomputer.com/sUBs/ComboFix.exe 

You must download it to and run it from your Desktop
Now STOP all your monitoring programs (Antivirus/Antispyware, Guards and Shields) as they could easily interfere with ComboFix.
Double click combofix.exe & follow the prompts.
When finished, it will produce a log. Please save that log and attach it in your next reply by pasting it in the "Code Snippet" or "Attach File" window.
Re-enable all the programs that were disabled during the running of ComboFix..

Note:
Do not mouse-click combofix's window while it is running. That may cause it to stall.
CF disconnects your machine from the internet. The connection is automatically restored before CF completes its run. If CF runs into difficulty and terminates prematurely, the connection can be manually restored by restarting your machine.

If needed, here's the Combofix tutorial which includes the installation of the Recovery Console:

Personally, I wouldnt install the recvovery console.

Or, we can start with a Hijack This Log file....

HijackThis!
http://hijackthis.de

Also, check in c:\Windows\system32, for the userinit.exe file. How big is it, and whats the date modified on it?

Also, also.....

Paste these 2 lines into a Start>Run>Cmd DOS Box, and give paste the results.....

reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v userinit
reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v shell
Make sure that you have the latest Service Pack install on your System. Latest being SP3

Combofix and hijack this are good but not a solutions for all.

Try using a spyware program like
Spyware Doctor  http://www.pctools.com/
or
my favorite Spysweeper www.webroot.com

"usernit file = 43.5k"
Thats about double the size of a standard Userinit.exe file......
I would seriously look at replacing it from the install CD, or from another working PC. Delete the copy in c:\windows\system32\dllcache first.....

When does this occur? as a result of the reg query commands?

Just go to start>run>regedit, and go to the following key in the registry, and give us the values for Shell, Userinit and Winlogon. Right click the whole Winlogon key, and select Export, and save here if needed....

Did you try running Combofix yet as John had suggested?

Combofix will replace any patched userinit.exe if a clean one is found in the system.
The log will also show us if other system files have been patched... could be a file infector at work there.

hello nothing that i did worked , so i reinstall xp and im installing the programs 1by1 i dont have the error anymore but was no way to fix it , i had to reinstall xp because somebody suggested to install SP3, and from there the pc didnt start any more, i checked what happened and before you install sp3 you have check your system of course i didnt and my pc just was off and sometimes with an blue screen error.so i was tired already of all of this , i think the more wise solution when this happen in the system before everything is worse is to do a clean install of xp, then drivers, etc.
anyway thanks for trying to help me.
regards.
