You can sort out the Trustedinstaller.exe issue by getting the rights to make changes on Windows. But before taking this step, research if there are any consequences when taking that approach. 

Seek guidance from an expert before deleting any file from Windows.

Here is how you can seek an administrator’s permission:

• Select the file you would like to modify then right-click on it
• Choose “Properties” and click “Security.”
• Locate the “Advanced” property on the bottom of the property Window.
• You will see the window “Advanced security settings” together with a list of permission entries. From here you can have a look at the details of the owner of the program or service you would like to modify. 
• This is where you will find the Trustedinstaller.exe file here.

Changing the Ownership

Now that you have accessed permission to modify the files on Windows, you can change the ownership. Now you can troubleshoot issues caused by this program. 

Follow the steps below:

Step 1:

• Click “Change.” This will open the “Select User or Group” box
• Write “Administrators” below the “Enter the object name to select” option
• Click the tab of “Check Names.” This will modify the ownership of windows automatically.
• Click “OK” to save changes.

Step 2:

• Go to the “Advanced Security Settings” window to check the ownership information. You will see “Administrators “and not “Trustedinstaller.exe.”
• Select the checkbox underneath the Owner section to confirm ownership.
• Tick the “Replace owner” on “Subcontainers and Objects” option.

Step 3:

• Go to the properties window by clicking “OK” button
• Click “Edit” and have a look at the items below the “Group and User Names.” 
• Look for “Administrators” and scroll down the “Permissions for Administrators” section.
• Select the “Allow” box that is located next to the “Full Control” feature. This allows you to delete, rename, and edit files as admin.

Most Windows professionals don’t recommend the last choice. The fourth choice is useful if you don’t want the Trustedinstaller.exe to overuse the memory of your PC.
