I am running XP Pro SP2. I didn't used to have any problems with this in particular, but I'll start from the beginning.

I went to the control panel to change the password.
It first began with the "Windows cannot change the password error", even though the password still changed on my account.
A few days later, my computer started bringing up the "Windows Security" menu when I hit Ctrl alt delete. The computer also wouldn't let me switch user. I knew how to enable switch user, but it gave me the "Windows cannot apply the Fast User Switching Setting you selected".

Is there a registry fix or something that might fix this. Or might there be some malware? I think it might be malware because even after restoring a backup of my computer the problem disappeared and returned after about a day or two.


Thanks in advance for any help :thumbsup:



Edit: I guess it's actually two problems, but I do think they are very closely related.
Edit: I also got my computer off of ebay with a memorex cd labeled "Windows XP Professional", so I don't know if that would make my installation of windows corrupt (which it probably isn't) but I might as well add.

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Thanks for the fast reply. The problem had actually mysteriously stopped even before I had started the scan. I ran the scan anyways, but it didn't seem to find any big problems. I will run the scan again if the problem comes up again.


Thanks for your help! That program does seem to have helped!

The problem just came up again! I tried running the Malware scan again, even the full one, but it didn't find a single thing because I already ran it recently. It isn't being detected as malware.

I have still tried to get the switch user setting back with no success; and the task manager doesn't pop-up immediately-the "Windows Security" menu with Task Manager as an option. This is both impairing the function of my computer and being quite annoying. Because it keeps reappearing, do you guys think it might be malware causing these issues?

Does anyone have any other techniques of trying to get rid of this?

The only thing I have done with the welcome screen was trying to create a hidden user account. That shouldn't cause any problems though.

Anyways, I haven't logged into that account for about a month now.

I haven't been messing around with the welcome screen and any important settings, if anything some malware did it.
Sometimes my computer just randomly Turns the power button into the old style on its own and also turns the ctrl alt del hotkey to go to windows security. I try to undo it but the computer just gives me error as stated before. It eventually goes back to normal but returns in the next day or two.

I didnt mess around with any important Windows settings something else is doing this.

I'm trying to install the Anti-Malware download but the virus won't let me, it's blocking it. Any suggestions? I've tried copying it to C drive, to desktop, to documets, etc., but it won't let me. And I can't connect to internet with infected computer because of the virus so I need to take it from one computer to the "sick" one. I've even considered doing a complete system restart, but I can't remember how to do that, so last resort, give me instructions on how to do that, if you can.

Dmlscr, you should really start your own thread to address these issues and I would suggest starting that thread in the Am I Infected section of this forum located here.....

Try this:

1. In Control Panel, click User Accounts.
2. Click Change the way users log on or off.
3. Select Use the welcome screen for fast and easy logon.
4. Click OK.
