Windows XP Automatically Logoff after logon

Posted on March 8th, 2009 by Jason

For long time ago , I experiment with this problem too many times. and what I can do with it is, Format and Reinstall the windows. But now This problems happened on my boss’s computer, That why I have to try my best to find the solution to fix for him.

I have google it many time ago, but still can not find the right solution for this kind of virus. But I think depending on the level of the infection. if you were in the medium ,you maybe lucky!

This problems happened after you clean that virus from your computer ( I don’t remember what is the name of virus). So if yo have the same problems as me , hope you maybe able to fix it also.

Step 1: Create a BartPe Bootable CD

“BartPE” (Bart Preinstalled Environment) is the bootable Windows CD-Rom or DVD from the original Windows XP that we can say Live CD that, very suitable for PC maintenance tasks.

To built it by ur selves please go to : http://www.nu2.nu/pebuilder/ to download the PeBuilder latest version and read the instruction to built your own bootable CD.

Step 2: Verifying and fixing the Userinit.ext

1. Insert the BartPE CD into the drive, and boot the system from the CD. Once the file loading phase is over, the Bart PE desktop will be visible.

2. Type Regedit.exe in the prompt, and press Enter. Select the HKEY_USERS hive.

3. From the File menu, choose the Load Hive option. Browse to your Windows installation drive

C:\Windows\System32\Config\

4. Select the file named SOFTWARE (the file without any extensions), and click Open.

5. Type a name for the hive that you’ve loaded now. (Example: MYHOUSE)

6. Now the SOFTWARE hive is loaded, and present under the HKEY_USERS base hive.

7. In order to fix the Userinit value in the loaded hive, navigate to the following location:

HKEY_USERS \ MYHOUSE\ Microsoft \ Windows NT \ CurrentVersion \ Winlogon

8. Double-click Userinit and set it’s value correctly. Example: Set it’s data as follows:

C:\Windows\System32\Userinit.exe,

Also Combofix has been my Saviour for fixing non explorer.exe loading problems.

If the above don’t work you can also extract and get another Userinit.exe and replace the one you have & get it to logon.

I have done all the the steps, creating the bartpe disc, and loading it first.. i have enter regedit, gone to hkey/_users and looked up the hive “software.log” and loaded that, but it will not let me access to install the file name “Myhouse”… is there another way around it? so i can rewrite the “userinit.exe” file?
