I am trying to help a friend with the following problem.

He is using Vista Home Premium. His user account has Aministration rights.
When he tries to uninstall a program he gets the following message “the system administrator has set policies to prevent this installation” followed by another prompt “you do not have sufficient access to uninstall ………program please contact your system administrator”

If he logs on as Administrator he can uninstall but clearly, he should not need to do this.

I have looked at the system policy settings in the registry but can't work out which one to change. The settings are in
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
Can anyone help please?

Settings are:
ConsentPromptBehaviorAdmin 0
ConsentPromptBehaviorUser 1
DD-ConsentPromptBehaviorAdmin 2
DD-PromptOnSecureDesktop 1
dontdisplaylastusername 0
EnableInstallerDetection 1
EnableLUA 1
EnableSecureUIAPaths 1
EnableUIADesktopToggle 0
EnableVirtualization 1
FilterAdministratorToken 0
legalnoticecaption
legalnoticetext
PromptOnSecureDesktop 0
scforceoption 0
shutdownwithoutlogon 1
undockwithoutlogon 1
ValidateAdminCodeSignatures 0

Welcome to HTG.
---
We have no way of knowing what your friend did or how he /she configured the machine.
---
Personally, I would advise that important data be backed up, the System "Nuked" and a Clean Install or Restore Made.

Maybe another member has memorized all the Policy plus Registry Settings and can help however they are not intuitive in many cases and are a book unto themselves.
---
EDIT: There are many other tricks you could do to fool the system, however I think from your post, you want to run an Out Of The Box Configuration so that's why the suggestion above.

This setup should let you do (nearly) anything,

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System]
"ConsentPromptBehaviorAdmin"=dword:00000002
"ConsentPromptBehaviorUser"=dword:00000001
"EnableInstallerDetection"=dword:00000001
"EnableLUA"=dword:00000000
"EnableSecureUIAPaths"=dword:00000001
"EnableVirtualization"=dword:00000001
"PromptOnSecureDesktop"=dword:00000001
"ValidateAdminCodeSignatures"=dword:00000000
"dontdisplaylastusername"=dword:00000000
"legalnoticecaption"=""
"legalnoticetext"=""
"scforceoption"=dword:00000000
"shutdownwithoutlogon"=dword:00000001
"undockwithoutlogon"=dword:00000001
"FilterAdministratorToken"=dword:00000000
"EnableUIADesktopToggle"=dword:00000000
"DisableLockWorkStation"=dword:00000001

LH - Thanks for your suggested settings. My concern with this is that, as far as I can tell, setting "EnableLUA"=dword:00000000 will disable UAC completely.
If it does disable UAC then a: I can do this easier from the Control Panel, User Accounts area and b: it leaves the system vulnerable to outside attacks (ie. installation of malware unbeknown to the user).
Am I wrong on this?
Thanks

You only need to disable it temporarily.
Yes, you are right.

LH - Thanks, but I need a permanent fix so that he can uninstall programs but is still protected by UAC.
Not sure what went wrong with his PC but this all started when he discovered last week that he couldn't uninstall anything. He then saw that his user account privilege was User where is was originally Administrator and he couldn't get into the Administrator account to reset it. I was able to reset the Aministrator account to blank using SpotMau but when his user account was reset to Admin rights he still could not uninstall software.
Apologies - I probably should have included this in my original post!

Edit by mod. Warning. If you do a search for SpotMau, be wary of what you click on. A lot of red flags on a Google search.
