Unhappy Solved: ctrl-alt-del doesn't work in the usual way.
Awhile back, I installed an alternative task manager (on the advice of a computer magazine) and set it up to replace the normal Windows Task Manager. Fine, but I didn't like the alternative. So I uninstalled it. Now, if I hit ctrl-alt-del, I don't get anything but a DOS window that closes quickly and automatically.

So how can I make ctrl-alt-del do what it normally does??

Try the fixes here:

Click on 'T' at the top and scroll down to Task Manager.

Luck!

ctrl-alt-del doesn't work -- and the solutions don't work
I tried those. It seems I have a virus (which I doubt) or I have to turn on the alerter service. How do I do that?

task manager
I found the task manager in the system32 directory. If I try to run it, I get the DOS window that flashed on and instantly off. What's the problem?

Click Start

Click Run

Type regedit

Click OK The Registry Editor will now open

Browse to the following key:
HKEY_CURRENT_USER\Software\Microsoft\Windows\
CurrentVersion\Policies\system

In the right pane, look for the value: DisableTaskMgr

Right click DisableTaskMgr and select Delete. (When prompted with "Are you sure you want to delete this value", select Yes.

Now browse to the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\
CurrentVersion\policies\system

In the right pane, look for the value: DisableTaskMgr

Right click DisableTaskMgr and select Delete. (When prompted with "Are you sure you want to delete this value", select Yes.

Close the Registry by choosing File | Exit

You should now be able to access Task Manager. If not, reboot into Safe Mode and repeat the steps outlined above.

For what it's worth, I found a suggestion on-line and I made a copy of taskmgr.exe and renamed it "taskmgr.com." That worked, unlike taskmgr.exe. Ctrl-alt-del still doesn't work.

If you run Task Manager from a command window, does it open?
Start => Run and type in cmd
In the window that opens, type in taskmgr

Maybe that replacement program you had somehow replaced the existing Task Manager. I've attached a copy, zipped. Unzip it and put it in C:\Windows\System32 - replacing the existing copy.

Thanks. If I run "taskmgr.exe" in (what I call) a DOS window, it doesn't work. "taskmgr" runs "taskmgr.com." I copied "taskmgr.exe" from Claymore's zip file into c:\windows\system32 and it didn't change anything.

I tried Karbo's advice. It didn't work and I can't figure out how to start in safe mode using this HP machine (pavilion a1540n). When I reboot, it jumps to the choice of "recovery," a boot menu (in case I want to boot from a CD), or the setup/BIOS program.

And just to add - it may not be actual malware, but some change made by the program you tried. You should probably run a virus scan anyway. It may pick up the change.

In case you need it, this should give you a working temporary replacement for the Task Manager:
http://www.dougknox.com/xp/utils/xp_emerutils.htm

You could also post a HiJackThis log if you want:

Download hijackthis here:
http://www.thespykiller.co.uk/files/HJTsetup.exe

Save HJTsetup.exe to your desktop.
Double-click on the HJTsetup.exe icon on your desktop.
By default it will install to C:\Program Files\HiJackThis.
Continue to click Next in the setup dialogue boxes until you get to the Select Additional Tasks dialogue.
Put a check next to 'Create a desktop icon' and click 'Next' again.
Continue to follow the rest of the prompts from there.
At the final dialogue box click 'Finish' and it will launch HijackThis.

Click on the 'Do a system scan and save a log file' button. It will scan and then ask you to save the log.
Click 'Save' to save the log file. The log will open in Notepad.
Click Edit => Select All => Edit => Copy.
Paste the log in your next post.

My computer has no viruses (virii?) Replacing taskmgr.exe with a new version doesn't seem to work. Claymore, I'm pretty sure there's no spy-ware. What next?

Hello again, Jim.
From what you described, I didn't think you could be infested, but it had to be checked.

Two suggestions:

Do a System Restore back to the time before you installed that program.

And/or
If you have an XP CD or access to an i386 folder:
Start = Run and type in:
sfc /scannow {space after sfc}
Let it run to the end.

p.s. Yes, it's "viruses". No such word as virii as a plural of virus

Hi,

I'll try the sfc /scannow tomorrow when I have time. But what does it do?

also, what is the "alerter"? Maybe my problem is with it?
