Task Manager Not Working

Cannot use Task Manager.

I am unable to use task manager. CTRL ALT DELETE takes me to the normal
screen, and displays everything but the task manager. I went to the System32
file to open it, and it said "Disabled by Administartor". There is only one
account on this computer, I am the only one who uses it, and I am on
administrator. I went to Microsoft's website, and found a help page for this
very problem, but their solution didn't work, it said to type "Gpedit.msc"
into run, but I received an error message saying that it did not recognize
it, and to check if I spelt it correctly. Retried multiple times, even used
copy and paste, still didn't work.

Re: Cannot use Task Manager.

Yo TM don't work no moah--

ctrl+alt+delete should always also work for TM in Vista. You don't
necessarily have to use ctrl+alt+escape. If TM's not coming up these and
System Restore is included: (I'm not sure what "MSFT fix" you refer to.
gpedit.msc in the run box should take you to group policy editor's list.
It's possible that someone could have turned off permissions for TM from
there, but not likely since you're the only one obstensibly with access to
that box).

You can try a "quickie SFC" first by going to [Vista Drive]\Windows\System32
and copying taskman from your system 32 folder to desktop. See if that
works. If not try these:

***SFC as a Remedy***:

SFC or System File Checker is a bit like the spare tire in your car or a
backup battery I suppose. In Vista of course, they have changed it somewhat
and come up with a new name--Redmond stands for name it something different
twice a year and now it's part of WRP or Windows Resource Protection. It
scans protected resources including thousands of files, libraries, critical
folders, and essential registry keys, and it replaces those that are
corrupted with intact ones. It fixes a lot of problems in Windows XP, OE,
Windows Vista, Win Mail, IE6, and on Vista or if it is installed on XP, IE7.
It protects these things from changes by any source including
administrators, by keeping a spare of most of them.

How to Run SFC:

Type "cmd" into the Search box above the Start Button>and when cmd comes up
at the top of the Start menu>right click cmd and click "run as Admin" and
when the cmd prompt comes up at the cmd prompt type "sfc /scannow" no quotes
and let it run. This may fix things quite a bit. It replaces corrupt files
with intact ones, if you're not familiar with it.

***Startup Repair from the Vista DVD***

How to Use The Vista DVD to Repair Vista (Startup Repair is misnamed by the
Win RE team and it can be used to fix many Vista components even when you
***can boot to Vista):


If you elect to run Startup repair from the Vista DVD (it can fix major
components in Vista--I've verified this many many times; it's good for more
than startup problems, and the Win RE team simply screwed up when they named
it not understanding its full functionality):

Startup Repair will look like this when you put in the Vista DVD:


You run the startup repair tool this way (and system restore from here is
also sometimes effective):


How To Run Startup Repair In Vista Ultimate (Multiple Screenshots)

It will automatically take you to this on your screen:


That will allow you to go to the Vista setup that has a Repair link on
thelower left corner>click it and then you'll see a gray backgrounded list
and I want you to click Startup Repair from it and follow the directions.

The gray screen after you click the first link in the above pic will look
like this:


Click Startup Repair, the link at the top and after it scans>click OK and
let it try to repair Vista. It will tell you if it does, and if it
doesn't, try System Restore from the Recovery Link on the DVD. If these
don't work booting into Safe Mode by tapping the F8 key and using System
Restore from one of the safe modes besides VGA may work. That means you
have the option to try 4 different safe modes to get to system restore, (one
from the Recovery link on the DVD) and sometimes one will work when the
others won't.

You could also try a Repair Install with Vista which is done exactly the
same way as in XP:

***Repair Install Steps*** (can be used for Vista) MVP Doug Knox

***Using the F8 Environment***

***Taking Full Advantage of the F8 Options (Windows Advanced Options Menu)
by starting the PC and tapping F8 once per second when the firmware screen
with the pc manufacturer's name shows a few seconds after restarting***:

The F8 options in Vista are the same as XP, and the link for Safe Mode Boot
options is labled XP by MSFT but they are the same for Vista (they haven't
updated to add Vista to the title as they have with several MSKBs that apply
to both).

Again, pressing F8 repeatedly when you seem the firmware screen may be is a
generic way to launch Windows RE on some OEM Vista computers.

You could also:

Think: I have 4 different ways to get back my XP at F8 and try 'em in order.
1) Safe Mode 2) Safe Mode with Cmd to Sys Restore which is simply a cmd
prompt in safe mode 3) Safe Mode with Neworking 4) LKG or Last Known Good

Try to F8 to the Windows Adv Options Menu>try 3 safe modes there (I don't
use WGA) and Last Known Good>then I go to Win RE in Vista. That gives you a
choice of Safe Mode, Safe Mode with Networking,and Safe Mode with Command

These methods are outlined in

A description of the Safe Mode Boot options in Windows XP/and Vista

Frequently Asked Questions Regarding System Restore from MSFT:


System Restore can be run from the Win RE recovery environment from the same
link as Startup Repair, and sometimes it will work from one F8 safe mode
location or from the Win Recovery Environment when it won't work from other

Re: Cannot use Task Manager.

I suggest you open a command prompt as administrator and run there.
Start/all programs/accessories right click on command prompt and select run
as administrator.

Re: Cannot use Task Manager.

I am having the same issue. I am the Administrator and it tells me certain
things are disabled. A program also changed my home page in IE and I can't
change it back. Windows Vista does not have "Gpedit.msc".

Re: Cannot use Task Manager.

You have listed the symptoms of a virus. I have Vista, and I have
gpedit.msc on Ultimate 86 and 64.
