As the Administrator, you might think that you have full control of your computer. But, when you try to delete some files on your computer, you get a message “You require permission from TrustedInstaller to make changes to this folder.” You try to press the Try Again button but nothing happens.
What cause this to happen? Microsoft creates an NT SERVICETrustedInstaller account on Windows to prevent the important files from being removed. Thus, you will see the notification when trying to delete them. But if you still want to delete the files, here are some steps to get the permission from TrustedInstaller.

Steps to Get Permission From TrustedInstaller to Make Changes to Files
But If you know what you are doing and persist in your action, here is how to claim the privilege from TrustedInstaller:
1) Right click on the file or the folder you want to change or delete, and select Properties.
2) On Properties window, open Security tab and then click on Advanced.
3) We are now going to change the Owner On Advanced Security Settings window. On Windows 10, you can click on Change next to Owner: TrustedInstaller.
But on Windows 7 or earlier versions, you need to select Owner tab and hit Edit. And on the window popping up, click on Other users or groups.
4) On the window popping up, type the user name you are using on this computer into the box and click Check Names button. Windows will automatically check and complete the full object name. Then click on OK.
5) Tick the box next to Replace owner on subcontainers and objects if you want to apply the ownership changes to all the subfolders and files. Then hit OK to close this window and go back to Properties.
On Windows 7, the Replace owner on subcontainers and objects box is below Other users or groups button.
6) Click Advanced again. Then click on Change permissions button under Permission entries
7) Click on Add. On Permission Entry window, click on Select a principal. A window similar to the one appeared in step 4 will show up again and you need to repeat step 4.
Tick the box next to Full control in Basic permissions section, and hit OK.
Check Replace all child object permission entries with inheritable permission entries from this object. After that, click on OK all the way out.
For Windows 7, you need to click on Change Permission button on Permissions tab to see Add button. Click on that and repeat step 4. After that, check the Allow box of Full control and click OK.
Check Replace all child object permissions with inheritable permissions from this object. Then click on OK all the way out.
8) Now you can delete the file that you have just changed ownership without the “You require permission from TrustedInstaller” message bothering you.
