In order to change the TrustedInstaller folder ownership: We recommend changing permissions on protected files only in extreme cases, when you understand exactly what you are doing.

Before deleting any system file, we recommend you to make a copy of it. Deleting or modifying protected system files owned by TrustedInstaller may cause Windows to crash. After this, do not forget to revert ownership back to TrustedInstaller. After that, you need to edit the NTFS file permissions, grant yourself write permission and delete/replace/change the file. If you want to delete a file or folder owned by TrustedInstaller, you need to take ownership of this folder/file. Make sure that the TrustedInstaller is set as an object Owner.
