Method 1: Disable or Turn Off UAC (User Account Control) in Control Panel
To use Control Panel to disable UAC in Windows 7, there are several methods to access the User Account Control settings page:
1.Go to Start Menu -> Control Panel -> User Accounts and Family Safety -> User Account.
2.Go to Start Menu -> Control Panel -> System and Security -> Action Center.
3.Click or right click on Flag icon in notification area (system tray), and then Open Action Center.
4.Type “MsConfig” in Start Search to start System Configuration, then go to Tools tab, select Change UAC Settings, then click on Launch button.
Click on User Account Control settings link.
Slide the slider bar to the lowest value with description Never notify.
Click OK to make the change effective.
Restart the computer to turn off User Access Control.
Method 2: Disable UAC with Registry Editor (RegEdit)
Run Registry Editor (RegEdit) and navigate to the following registry key:
Locate the following REG_DWORD value:
Set the value of EnableLUA to 0.
Optional step to suppress UAC consent prompt dialog, locate the following REG_DWORD value:
Set the value of ConsentPromptBehaviorAdmin to 0 (optional).
Exit from Registry Editor and restart the computer to turn off UAC.
Method 3: Turn Off UAC Using Group Policy
For Windows 7 Ultimate, Business or Enterprise edition which has Local Group Policy, or computer joined to domain and has Active Directory-based GPO, the group policy can be used to disable UAC for local computer or many computer across large networks at once.
1. Enter GPedit.msc in Start Search to run Local Group Policy editor. (Or gpmc.msc to run Group Policy Management Console for AD-based domain GPO editor).
2. Navigate to the following tree branch:
Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options
3. Locate the following policy in the right pane:
User Account Control: Behavior of the elevation prompt for administrators in Admin Approval Mode
Set its value to Elevate without prompt.
4. Locate the following policy in the right pane:
User Account Control: Detect application installations and prompt for elevation
Set its value to Disabled.
5. Locate the following policy in the right pane:
User Account Control: Run all administrators in Admin Approval Mode
Set its value to Disabled.
6. Locate the following policy in the right pane:
User Account Control: Only elevate UIAccess applications that are installed in secure locations
Set its value to Disabled.
7. Restart the computer when done.
Method 4: Using Command Prompt to Disable User Account Control
The command line option can also be used in batch script command file, i.e. .bat and .cmd files, providing greater convenient to advanced technical user. In actual, the commands,, which are also used to disable or enable UAC in Vista, are just doing the same thing as directly modifying the registry.
1. Open an elevated command prompt as administrator.
2. To disable the UAC, run the following commands:
%windir%\System32\reg.exe ADD HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v EnableLUA /t REG_DWORD /d 0 /f
and optionally, the following comand to suppress all elevation consent request and notification:
%windir%\System32\reg.exe ADD HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v ConsentPromptBehaviorAdmin /t REG_DWORD /d 0 /f
Tip: To re-enable UAC, the command is:
%windir%\System32\reg.exe ADD HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v EnableLUA /t REG_DWORD /d 1 /f
and to turn on prompt for consent UI:
%windir%\System32\reg.exe ADD HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v ConsentPromptBehaviorAdmin /t REG_DWORD /d 2 /f
Note: Disabling UAC may cause gadgets stop working in Windows 7. Users who are facing this issue may use another workaround to suppress User Account Control.
To answer your question: There are no risks to disabling UAC, as long as you run as a standard user.
You should always run as a standard user on Windows.
On Windows XP/Vista/7, you can create an account that is a standard user. The downside of this is that if you want to perform anything that requires administrative access to the computer, e.g.:
•installing software into program files
•editing local machine registry settings
you will have to fast-user switch to an administrator account in order to perform the operation, then switch back.
Nobody wants to actually run as a standard user all the time, so they run as an administrator full time. The risks of running as an administrator is that you can accidentally damage your Windows installation. Running malware, or a security breach, can take complete control of your computer.
UAC is the comprimise, where you are stripped of your admin privelages, unless something comes along that requires admin access. UAC temporarily grants you admin privelages, until that operation is complete.
•Running with UAC enabled is the same as running as a standard user.
•Running with UAC disabled is the same as running as an administrator.
•Running as an administrator is a risk.
Note: ie and Chrome will still use protected mode with UAC disabled.
UAC is a technology where you are stripped of your admin privelages, so you can't do damage. Internet Explorer and Google Chrome both take advantage of a similar feature available since Vista. They run in protected mode; they run with less privelages than even standard user.
Even if you disable UAC, and run as an administrator full-time, your browser will still run lower than you, to protect you from you.
Note: Firefox does not support protected mode, and will run with the same privelages as you are. i.e.:
•Administrator, UAC enabled: runs as standard user
•Administrator, UAC disabled: runs as administrator
•Standard user, UAC enabled: runs as standard user
•Stardard user, UAC disabled: runs as standard user
i don't recommend anyone disable UAC. But if you must, run as a standard user. If you cannot stand runnnig as a standard user, run Internet Explorer or Google Chrome. If you use Firefox, as an administrator, with UAC disabled, and you encounter a security vulnerability (e.g. you used flash last year) your computer can be completely taken over.
If you run as a standard user, then it is safe to enable the built-in Administrator account. You then use Administrator when prompted for admin credentials for protected, global configuration settings and installing/removing software to c:\program files\. – Brian Reiter Dec 15 at 22:51
@Brian: that assumes that UAC is enabled, and you're not running as with an administrator account yourself. With UAC disabled you will not get an elevation prompt (whether or not you're a standard user) – Ian Boyd Dec 16 at 14:59
Under that scenario, it makes sense to leave UAC enabled. That way, when you're logged in to your non-admin account, you can still elevate when you have to, rather than having to switch users to do administrative tasks. Properly configured, UAC essentially IS running as a limited user, and elevating when you have to. It makes a lot of sense to use it. – nhinkle Dec 17 at 3:54
nhinkle: You are right. But if you're going to have UAC enabled, then you might as well run with an administrative account. You'll be stripped of your admin privelages; being granted them back only when you need them. The advantage then is that you only have to push "Continue", rather than entering a different set of credentials. Basically, there is NO reason to disable UAC. –
Here is one of two ways to turn off UAC in Windows 7:
1.Access User Control Panel from
•User Accounts and Family Safety
2.Click on User Account Control settings link.
3.Move the Slider to Never Notify
4.Click OK to make the change effective.
