Starting with Windows Vista, even if an app is running elevated, it may have no access to certain Registry keys and files. A new security model introduced in Windows Vista comes with a special user account, TrustedInstaller, which is set as the owner for such files and Registry keys. However, if you execute a program as TrustedInstaller, then you are able to access these protected resources. To simplify running apps as TrustedInstaller, I coded ExecTI, a lightweight, tiny software, which allows you to do exactly that using a nice GUI.
ExecTI is my latest project. I got tired of having to take ownership and grant administrator privileges for protected Registry keys and files during the various tests I perform on my Windows PC. I also wanted to create such an app a long time ago, but always postponed it due to lack of time. Finally, I am happy to share it with you.
Here is how ExecTI looks:
It has a simple user interface. The application has no other dialog, and options at all. It allows you to browse for an executable file (exe, cmd, or bat file), or you can type the command directly in the text box.
It is possible to enter the command with command-line arguments. For example, you can type:
To open yet another instance of Registry Editor.
As you can see, you cannot modify anything under this key. That is because it is owned by TrustedInstaller (see the screenshot below):
Now, run Registry Editor with ExecTI. Voila, you can make any changes under that Registry key!
ExecTI supports Windows 7, Windows 8/8.1, Windows 10 and Windows 11. It should work under Windows Vista too, but I am not able to test it there.
Before you download the app, here is the note of caution:
Running programs under TrustedInstaller privileges, especially a file manager app or Regedit.exe can be VERY risky and harmful for your OS. It is like a God mode in a first-person shooter game, where nothing can stop your actions, so if you execute a malware infected file as TrustedInstaller, it can cause damage to the Windows operating system. Use this mode only if you perfectly understand what you are doing and if there is no simpler way than running it as Trusted Installer.
Update. The app is now part of Winaero Tweaker.
I recommend that you get Winaero Tweaker instead of downloading my standalone app, which nevertheless remains available.
