 # RunAsTrustedInstaller
-Windows command-line utility to run programs with TrustedInstaller privileges
+A Windows command-line utility to run programs with TrustedInstaller privileges.
+
+## Description
+On Windows, TrustedInstaller privileges sometimes can be helpful to modify/delete criticial system files/folders that are protected by the OS.  
+Likewise, there might be a need to deal with certain Registry keys that are protected with an ACL which restricts access the TrustedInstaller account.  
+The utility was developed as a standalone executable and does not require any installation.
+
+## Getting Started
+
+### Compilation
+```
+cmake .
+cmake --build .
+```
+Alternatively, you can simply open `CMakeLists.txt` in Visual Studio and compile from there.
+
+### Usage Examples
+
+Delete a file that cannot be deleted the regular way:
+```
+RunAsTI.exe cmd.exe /c del C:\Windows\system32\foobar.dat
+```
+
+Open the Registry Editor to view/modify/delete Registry keys/values that are not accessible in normal operation mode:
+```
+RunAsTI.exe C:\Windows\regedit.exe
+```
