Fix You require permission from trustedinstaller windows 10

On Windows Operating system while trying to delete files or contents inside a folder, you may get a message You require permission from TrustedInstaller. Although you may say that why would i need permission to delete a file inside a particular folder when i have looged in as Administrator. The reason is that Windows has a Built in System Account named Trustedinstaller to prevent certain important files from being deleted or modified.

So, if you want to modify or delete certain kind of files of these type, you need to take ownership of these folder/files. Otherwise you will always be greeted with the Prompt. Here is how to Take ownership of the files and Get rid of this prompt. Note, that for important files , you must revert ownership back to trustedinstaller after doing the change.

 

Fix 1 – Using Command prompt

1. Search CMD in windows 10 search box.

2. Right click on the cmd icon and click on run as administrator.

3. Now, run the commands given below one by one.

takeown /F "path_of_folder_you_want_to_delete" /r /d y

 

icacls "path_of_folder_you_want_to_delete" /grant Administrators:F /t

 

rd "path_of_folder_you_want_to_delete" /S /Q

 

Just replace the full path by path of the folder.

To copy path of the folder just open the folder.

 

Then copy the path of the folder from the address bar.

 

 

So, in My case the commands i will execute are : –

takeown /F "C:\Users\SAURAV\Desktop\office folder\unnecessary files" /r /d y

icacls "C:\Users\SAURAV\Desktop\office folder\unnecessary files" /grant Administrators:F /t

rd "C:\Users\SAURAV\Desktop\office folder\unnecessary files" /S /Q
