Hi, I have been trying to disable user account control in Windows Vista SP2 in order to give a non-admin account more flexibility - specifically the ability to save files to an external USB drive. When the user tries to save a file they get a prompt stating that they require administrator permission. Usually I disable UAC by going into the Control Panel - User Accounts - Unchecking the "Use UAC" box, then restarting. I have one system where this will not stick - UAC continues to be enabled (the box is still checked even though i unchecked before restarting). I have also tried to do the following before a restart: Set the EnableLUA registry key to 0 Disable UAC via MSCONFIG Setting UAC settings to Disabled in the local security options Both had the same result - UAC is still enabled. Is there any other way to disable UAC and make it stick?

Hi, Please change the Non-administrator account to Standard account. http://windows.microsoft.com/en-US/windows-vista/Change-a-users-account-type Regards,Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

I tried this, the Non-administrator account was already set to a standard user account. I also tried to create a new standard user account under Computer management but the problem continues.

I don't think it's a group policy thing but you can check by Click Start - All Programs - Accessories - Right click Command Prompt and choose Run As Administrator. Type gpresult /z I assume the registry key stays set until you reboot. If so download Process Monitor from http://technet.microsoft.com/en-us/sysinternals/bb896645 Start the program as an administrator (right click and choose Run As Administrator). Set the filter to Path Contains EnableLUA Include then Add then Ok. Click Options menu - Enable Boot Logging Reboot. Change the registry key. Reboot. Run Process Monitor this will tell us if something is changing the value on shutdown. In case something is changing it on startup. Run Process Monitor. Choose Enable Boot Logging. Change the registry key. Reboot. What does Process Monitor show for operations on that registry value. To copy a line Select it and choose Copy on the Edit menu. -- .. -- "Crispy1014" wrote in message news:245f62a8-ef8c-4a54-b709-59d486f94fcb... >I tried this, the Non-administrator account was already set to a standard >user account.

Thanks - after running Process Monitor I got some logs. I have not checked thoroughly yet but it looks like sometime in the reboot process, the registry key itself is deleted altogether, then a new key gets put in with the original value.

You'll be looking for operations such as RegDeleteValue, RegDeleteKey, RegSetValue, or RegSetKeyValue. The operation will have a process name which I suspect will be a security program. Don't forget that Group Policy can act this way. Setting values on boot and once per hour after bootup. So make sure you run GPResult /z in a command prompt and look for a policy that includes EnableLUA. -- .. -- "Crispy1014" wrote in message news:97fcc2f6-d23b-4fdd-96c1-1c1b85fcdaae... > Thanks - after running Process Monitor I got some logs.
