Update Reminds Users Again Again Being

When started, many programs require permission pinnacle (shield on the app icon), but actually they don't need the administrator privileges for their normal operation. For instance, you tin manually grant permissions for your users on the app folder in the ProgramFiles and/or registry keys used by the program. So when starting such a program under not-admin user account, a UAC prompt volition appear and the user will be required to enter an administrator password (if User Business relationship Command is enabled on the estimator). To bypass this machinery, many users simple disable UAC or grant admin privileges to a user by adding a user business relationship to the local group "Administrators". Of form, both methods are not safety.

Why some Windows apps not run nether standard users and require administrator permissions?

An app may need the administrator privileges to modify some files (logs, configs, etc.) in its ain binder in the C:\Program Files (x86)\SomeApp. By default, users don't have edit (write and modify) permissions on this directory. In order this program to work ordinarily, the ambassador permissions are required. To solve this trouble, you accept to manually grant the change and/or write permission for a user (or the built-in Users grouping) on the app folder at the NTFS file system level.

Annotation. Actually, it is not recommended to shop the changing awarding data in its ain folder under C:\Program Files. It'south better to store the app data in the user contour. But it is a question of laziness and incompetence of the app developers.

How to run a programme that requires admin privileges under standard user?

Earlier nosotros described how to disable a UAC prompt for the certain app using RunAsInvoker parameter. However, this method is not flexible plenty.

Y'all can also use RunAs with the saved administrator password (in the Windows Credentials Director) using the /SAVECRED option. It is also insecure because the user tin can use the saved ambassador credentials password to run any programme on this computer.

Let'due south consider an easier way to force whatever program to run without administrator privileges (without entering the admin password) and with UAC enabled (Level iv, 3 or 2 of the UAC slider).

Let'south accept the Registry Editor every bit an example — regedit.exe (it is located in the C:\Windows\ folder). Observe the UAC shield next to the app icon. This icon means that meridian of privileges via UAC will be requested to run this program.

If you run regedit.exe, you will meet a User Account Command window request for the ambassador credentials (Do you lot desire to allow this app to make changes to your device?). If you do not provide a password and practise non ostend superlative, the app won't starting time.

Allow's try to bypass the UAC request for this program. Create the text file run-as-non-admin.bat containing the following code on your Desktop:

cmd /min /C "set __COMPAT_LAYER=RUNASINVOKER && start "" %ane"

To force the regedit.exe to run without the administrator privileges and to suppress the UAC prompt, elementary elevate the EXE file you want to start to this BAT file on the desktop.

Then the Registry Editor should start without a UAC prompt and without entering an administrator password. If you open up the Task Managing director and add the Elevated column, you will encounter that there is the regedit.exe process without the elevated status (run with non-admin user permissions).

Try to edit whatever parameter in the HKEY_LOCAL_MACHINE registry hive. As you tin see, a user cannot edit the detail in this registry primal (the user doesn't accept write permissions to the system registry keys). Simply you can add or edit registry keys and parameters in your user hive — HKEY_CURRENT_USER.

In the aforementioned way you can run any app using the BAT file. Simply specify the path to the executable file.

run-app-as-not-admin.bat
Set ApplicationPath="C:\Plan Files\SomeApp\testapp.exe"
cmd /min /C "fix __COMPAT_LAYER=RUNASINVOKER && start "" %ApplicationPath%"

Y'all can too add a context carte du jour that allows to run all apps without elevation. To do information technology, create the RunAsUser.REG file, re-create the post-obit code into it, relieve and import it into the Windows registry past double clicking on the reg file (you lot will need administrator permissions to utilize this alter).

Windows Registry Editor Version five.00 [HKEY_CLASSES_ROOT\*\vanquish\forcerunasinvoker] @="Run as user without UAC privilege summit" [HKEY_CLASSES_ROOT\*\shell\forcerunasinvoker\command] @="cmd /min /C \"set __COMPAT_LAYER=RUNASINVOKER && start \"\" \"%1\"\""

Subsequently that, to run any application without the administrator privileges, merely select "Run equally user without UAC privilege elevation" in the context carte du jour of File Explorer.

Allow me remind you once over again that using the plan in the RUNASINVOKER mode won't allow you to elevate the plan. The RunAsInvoker suppresses UAC prompt and tells the program that information technology should run with the permissions of the current user, and not inquire for elevation of privileges. If a plan really needs elevated privileges to edit arrangement settings or files, it won't work or will ask for admin permissions over again.

How to Featherbed UAC with RunAsInvoker in __COMPAT_LAYER?

The environment variable __COMPAT_LAYER allows you lot to set unlike compatibility levels for the applications (the Compatibility tab in the properties of an EXE file). Using this variable, you lot can specify the compatibility settings to be used when starting a program. For instance, to start an app in Windows 8 compatibility mode and 640×480 resolution, set up the following:

set __COMPAT_LAYER=Win8RTM 640x480

The __COMPAT_LAYER variable has some options we are interested in. At that place are the post-obit parameters:

• RunAsInvoker – run an app with the privileges of a parent procedure without the UAC prompt;
• RunAsHighest – run a program with the highest-level permission available to the user (the UAC prompt will appear if a user has the administrator privileges);
• RunAsAdmin – run an app every bit administrator (the UAC prompt appears each fourth dimension).

It ways that the RunAsInvoker parameter doesn't provide the administrator permissions, but just suppresses the UAC prompt.

The following CMD code enables the RunAsInvoker mode for the electric current process and runs the specified program without meridian:

set __COMPAT_LAYER=RUNASINVOKER
get-go "" "C:\Program Files\MyApp\testapp.exe"

Enable RunAsInvoker Fashion in the EXE File Manifest

As we said higher up, Windows 10 displays a UAC shield icon for programs that require elevation to run. Developers fix this requirement when compiling the awarding in the programme manifest .

Y'all can edit the manifest of any exe file and disable the requirement to run the program in elevated mode.

To edit the programme manifest, yous can employ the free Resources Hacker tool. Open the executable file of the app in Resource Hacker.

In the tree on the left, go to the Manifest department and open the program manifest. Pay attention to the following xml section:

<requestedPrivileges> <requestedExecutionLevel level="requireAdministrator" uiAccess="false"/> </requestedPrivileges>

It is thanks to the requireAdministrator option that Windows always tries to run this program as an ambassador.

Alter requireAdministrator to asInvoker and the save changes in exe file.

Note that at present the UAC shield has disappeared from the program icon, and you can run it without asking for ambassador password with the current user permissions.

If the executable app file is signed with MS Authenticode (Code Signing certificate), and then subsequently modifying the exe file, it may cease working or issue a warning.

In this case, yous can force the program to employ an external manifest file. Create a plain text file appname.exe.manifest (for example, Autologon.exe.manifest) in the directory with the exe file and copy the manifest code from Resource Hacker into it. Modify requireAdministrator to asInvoker. Save the manifest file.

To have Windows always try to use the external manifest file when launching exe files, enable a special registry parameter:

REG Add "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\SideBySide" /v PreferExternalManifest /t REG_DWORD /d 1 /f

Restart Windows and make sure the program is using an external manifest file that says to run without administrator privileges.
