ExecTI - Run as TrustedInstaller

ExecTI is a small free utility by Sergey Tkachenko of Winaero that runs programs with TrustedInstaller privileges. TrustedInstaller is a special Windows account, introduced with Windows Vista, that owns many system files and registry keys, so even an elevated administrator cannot change them. A program started through ExecTI gets full access to these protected resources.

Features:

• Runs a program, batch file or command script as TrustedInstaller.
• Accepts .exe, .cmd and .bat files, including command-line arguments such as regedit.exe -m.
• Window similar to the Windows Run dialog, with an Open field and a Browse button.
• Lets you open Registry Editor or a command prompt with access to protected keys and files.
• Useful for editing or deleting system files and registry keys owned by TrustedInstaller.
• Portable: no installation is needed, just unpack the archive and run the executable.
• Works on Windows 7, Windows 8/8.1, Windows 10 and Windows 11.
• Free to use; the same function is also built into Winaero Tweaker.
• Should be used with care: a program running as TrustedInstaller can damage the operating system, and a malware-infected file started this way can do the same.

ExecTI lets you edit system files and registry keys owned by TrustedInstaller that even administrators cannot change.
