1. TrustedInstaller description

Compared with the previous windows xp and previous versions, the security of the Windows7 operating system is much better, and the permission control of the system files is more stringent, so the system files can not be modified without authorization. For example, when we want to delete unnecessary windows built-in input method files, we will be prompted to deny access. There are many friends will encounter some programs can not run the situation, most of these situations are caused by the lack of access to the relevant permissions, that is, the so-called "compatibility issues." As shown in the figure:

Many windows users think that the account permissions in administrator or administrators groups are the highest permissions, but in some cases, TrustedInstaller permissions are the highest permissions to lock Win7! So similar to the above situation, how should we get the highest permission "TrustedInstaller permission" of the win7 system?

2. Obtain TrustedInstaller permission

1, method 1:

1) right-click the file or folder you want to operate, and enter "Properties → Security → Advanced → owner → Editing"

2) in the "change owner to" column, select the administrator user who logs in to the system, then select "apply", and click OK all the time.

3) go back to the folder properties window, go to the "Security" tab, and select "Edit"

4) Select the administrator user who logs in to the system in the bar above the permissions window, and select all "allow" in the column below.

After setting up, click OK until it is finished, and then the user has the administrative rights of the file or folder, that is, the highest administrative rights of TrustedInstaller of the window7 system are activated.

Explanation: this method is more cumbersome, is there a better way? Of course there is. Please read on to method two.

2. Method 2:

Write the following to notepad and save it as 1.reg

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\ *\ shell\ runas]

@ = "get TrustedInstaller permissions"

[HKEY_CLASSES_ROOT\ *\ shell\ runas\ command]

@ = "cmd.exe / c takeown / f\" 1\ "& & icacls\" 1\ "/ grant administrators:F"

"IsolatedCommand" = "cmd.exe / c takeown / f\" 1\ "& & icacls\" 1\ "/ grant administrators:F"

[HKEY_CLASSES_ROOT\ Directory\ shell\ runas]

@ = "get TrustedInstaller permissions"

"NoWorkingDirectory" = ""

[HKEY_CLASSES_ROOT\ Directory\ shell\ runas\ command]

@ = "cmd.exe / c takeown / f\"% 1\ "/ r / d y & & icacls\"% 1\ "/ grant administrators:F / t"

"IsolatedCommand" = "cmd.exe / c takeown / f\"% 1\ "/ r / d y & & icacls\"% 1\ "/ grant administrators:F / t"

After double-clicking to run 1.reg, the right-click on the file or directory to which you want to obtain TrustedInstaller permission will appear as shown in the figure:

A black window will pop up, apply permissions, and then you can delete this directory.

III. Summary

The above methods can only be tested under win7. Other systems should try it on their own. After obtaining the TrustedInstaller permission, basically any file can be deleted, provided that the file or directory is not occupied (run). In addition, please take care of the system file when deleting it, otherwise it will destroy the system file and cause the system to fail to function properly.
