System permissions in Windows version 7 have undergone significant changes. Windows Secure Protection is used instead of Windows File Protection, so even administrators do not have sufficient permissions to access system files.
Instructions
Step 1
Accessing system files in Windows 7 requires changing the permissions for TrustedInstaller.exe, which uses the Windows Modules Installer service. Attempts to modify system files or registry keys will result in a permission message from TrustedInstaller being displayed.
Step 2
In order to change this position and make changes to the access permissions to system files, open the context menu of the required file by right-clicking, select the "Properties" item and select the "Security" tab in the dialog box that opens. Use the Advanced button in the TrustedInstaller Group Permissions section and select Modify in the next dialog box.
Step 3
Confirm the execution of the selected action by clicking OK, and specify the administrator group in the "Change owner to" line. Save your changes by clicking OK, and apply them by clicking OK again in the system query window. Call the context menu of the selected file again by clicking the right mouse button and again use the "Security" tab.
Step 4
Click the Edit button in the Groups and Users section and specify the Administrators group in the directory of the dialog box that opens. Apply the checkbox in the "Full Control" line in the "Permissions for the Administrators group" section and confirm the saving of the changes made by clicking the "Apply" button.
Step 5
To restore the original permissions, repeat all of the above steps and uncheck the Full Control box in the Administrators group permissions section. Check the checkboxes in the "Read and Execute" and "Read" lines and confirm the execution of the selected action by clicking the "Apply" button.
Step 6
After that, go to the "Owner" tab and select the "Other users or groups" command. Print
NT SERVICE / TrustedInstaller
in the Enter Names box and click the Check Names button. Confirm restoring system file permissions by clicking OK in the next dialog box.
