Lost Admin Rights in Win XP Pro in local laptop and Win XP Home in home PC

Kakatua
I have lost partial User Admin Rights for all users who earlier had admin rights in my laptop with XP Pro and in my PC with XP Home edition. Both are standalone computers and are not part of any domain. I already tried different things in the computers to rectify the prob, including going through the other solutions in Techrepublic, but nothing is helping me out. The user rights are showing administrator correctly in control panel, though I am not able to install Service Pack 3 (XP Pro) and some other applications... getting error that I donot have sufficient admin rights to perform the task. However some applications and updates are getting installed fine without any problem. But most of the big applications are not getting installed. Also I am getting errors that I donot have sufficient privilege to make the change, whenever I am changing any settings in MSCONFIG, though the changes are going through fine but with the error msg. Please help as I cannot install lot of important security updates including Service Pack 3 and also some other imp apps. Thank you in advance for your support.

There is another way to check to see if the user has administrative rights. To do this right click on my computer and select manage. Under System tools and Local Users and groups and then the users folder select the properties of the user that is suppose to have administrative rights. Select the Tab member of and see if it says administrator. If it does it should be fine. If not in the meantime can you enter safemode with networking to install these updates

Check out whether your task manager (Ctrl+At+Del) has been disabled, if it has try thes steps and then try the Antivirus.

<br><br>
<i>Task Manager has been disabled by your administrator</i> error
When you try to open task manager, you may get the following error Task Manager has been disabled by your administrator. This happens if there is restriction in the registry-DisableTaskMgr value becomes one(1) instead of zero(0).In XP Professional it may be blocked via the "Local Group Policy" or "Domain Group Policy".
<br><br><br><br>

RESOLUTION:-
<br><br>

XP Home Edition
<br><br>

Click Start, Run and type in regedt32.exe and press OK.
Navigate to the following location
Software\Microsoft\Windows\CurrentVersion\Policies\System. expand the + on DisableTaskMgr. If it is not there create a new DWORD valued named "DisableTaskMgr" 0 = default enable Task Manager, 1 = disable Task Manager. Set the data value to zero.

<br><br>
Restart the PC.

<br><br>

XP Pro
<br><br>

Click Start, Run and type in gpedit.msc and press OK.
<br><br>

Expand the + with the left mouse button on Administrative Templates under the User Configuration.
<br><br>

Expand the + with the left mouse button on System. Left click on Ctrl+Alt+Del options.
<br><br>

In the right hand pane select Remove Task Manager. Right click on it and select Properties. If this setting is enabled and users try to start Task Manager, a message appears explaining that a policy prevents the action. So by disabling the policy, you are enabling the Task Manager. Click on Setting, Select the Disabled radio button, Apply and press OK.

VIRUS Removal
<br><br>

From another PC download and install these two programs and copy the the installed folders to a USB Stick.
<br><br>

Restart the PC in Safe Mode and turn off System Restore and run Sophos and then run Spybot.
<br><br>

Download Spybot - Search & Destroy 1.5.2 and install it. Update it. http://www.safer-networking.org/en/download/index.html

<br><br>
Download Sophos and the latest IDE Files. Install it and extract the IDE files to the C:\SAV32CLI folder.
http://www.sophos.com/support/knowledgebase/article/13251.html
<br><br>

Copy and paste the below two lines into Notepad and save the file to the USB Stick as sophos.bat, it will scan and remove. When the Scan has finished check the log file to see what it hasn't removed. You will normally find the answer to this via Google.
<br><br>
===============================
<br><br>
CD SAV32CLI
SAV32CLI -REMOVE -P=C:\REMOVLOG.TXT
<br><br>
===============================
<br><br>
The Sophos SAV32CLI folder can be safely deleted after it is copied to USB.
<br><br>
Whe you are convinced that you are clean turn on System Restore.

A couple more ideas.

How to reset security settings back to the defaults

Here are some steps that can be used to download and run the SubInACL tool to repair file and registry permissions that are often needed to successfully install programs on Windows, particularly for MSI-based (Windows Installer) setups:
<br><br>
Download the SubInACL tool and install it.

<br><br>
http://www.microsoft.com/downloads/details.aspx?FamilyId=E8BA3E56-D8FE-4A91-93CF-ED6985E3927B&displaylang=en
<br><br>
By default it will install to c:\Program Files\Windows Resource Kits\Tools
Go to the Start menu, choose Run, type cmd and click OK
Type notepad reset.cmd and click yes to create a new file named reset.cmd
Copy and paste the following contents into reset.cmd
<br><br>
cd /d "%programfiles%\Windows Resource Kits\Tools"
subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=administrators=f /grant=system=f
subinacl /subkeyreg HKEY_CURRENT_USER /grant=administrators=f /grant=system=f
subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=administrators=f /grant=system=f
subinacl /subdirectories %SystemDrive% /grant=administrators=f /grant=system=f
subinacl /subdirectories %windir%\*.* /grant=administrators=f /grant=system=f
<br><br>

Type reset.cmd and press enter to run the SubInACL tool (you will need to have adminstrator privileges for this to run correctly). This tool will take several minutes to run
After reset.cmd completes, try to install the product that previously failed to install correctly on your system
<br><br>
When is SubInACL useful
<br><br>
I have found that the SubInACL tool is most useful when a setup package fails with error code 5 or 0x5 or 0x80070005. All of these error codes mean Access Denied, and this type of error code is often caused by missing ACLs for the Administrators group or the built-in System account. The Windows Installer service runs with System account permissions in most cases. If the System account does not have sufficient permissions to access the file system or parts of the registry, an MSI-based setup package will fail with an Access Denied error.
<br><br>
SubInACL can also help resolve Internet Explorer script errors caused by incorrect access control permissions for specific user accounts on the system.
