HiI tried taking one of my old SSD's from a pc that does not work anymore and use it on my new pc and thus want to fully clean it as it has another windows installed etc. Initially i tried using command prompt to clean the disk but was met with an error telling me i do not have permission.Then i tried doing it manually in the folder which keeps telling me the files are protected by "Trusted Installer". I tried changing my administrator setting using properties, but when trying to uninstall i get told that i need permission from that user now to make changes to the folder. I am thinking the re

Trusted Installer

Hi Diane ,

Thank you for posting your query on Microsoft Community. We are sorry for the inconvenience caused.

I see that you are facing issues when you are trying to delete files.

Trusted installer's main function is to enable installation, removal and modification of Windows Updates and optional system components.

For this issue, I suggest that you try to change the ownership of the file that you are not able to delete and check if the issue persist.

Please login to administrator account before performing the below steps.

Follow the steps mentioned below to change the ownership of the file or folder:

• Press and hold the folder that you want to take ownership of, then tap
  Properties. (If you are using a mouse, right-click the folder, and then click
  Properties.)
• Tap or click the Security tab, tap or click Advanced, then tap or click
  Change. If you are prompted for an administrator password or for confirmation, type the password or provide confirmation.
• Type the name of the person that you want to give ownership to, and then click
  Check Names.
• Note: the account name for the person that you are assigning ownership to is displayed.
• Click OK.
• If you want this person to be the owner of the files and subfolders that are contained in this folder, select the
  Replace owner on subcontainers and objects check box.
• Click OK.

After trying all the above steps I would suggest you to try deleting the specific file which you weren’t able to delete.

Reply us if you have further queries we will be glad to assist you.

 

C windows installer folder - Delete?

He can do symbolic link redirection and move the files in it to a different location. *Wink
Better try it out in a virtual of first. Just a suggestion.

Like:
First move everything in c:\windows\installer to d:\installercache
Then delete c:\windows\installer folder
Then type this in command mode as admin
mklink /d c:\windows\installer d:\installercache

Removing those installer files is a bad idea. it might prevent you from updating or uninstalling apps.
