Unless I specifically say that commands need to be separated, copy/pasting the list is fine (and a lot quicker than attempting to retype them yourself! )
OK - we need to create a new registry Key, but I suspect that the first attempt will fail (but if it works, it's a loss of hassle avoided!)
Please open an Elevated Command Prompt, and run the following commands (Use copy/paste - there's only three commands!)
REG ADD "HKLM\Software\Microsoft\Windows\CurrentVersion\Component Based Servicing\Version"
REG ADD "HKLM\Software\Microsoft\Windows\CurrentVersion\Component Based Servicing\Version" /v 6.1.7600.16385 /t REG_EXPAND_SZ /d %SystemRoot%\winsxs\amd64_microsoft-windows-trustedinstaller_31bf3856ad364e35_6.1.7600.16385_none_ed02252b66d7bca2
REG QUERY "HKLM\Software\Microsoft\Windows\CurrentVersion\Component Based Servicing\Version"
Post the results.
then reboot, and run the following commands in an Elevated Command Prompt window - post the results in another reply.
REG QUERY "HKLM\Software\Microsoft\Windows\CurrentVersion\Component Based Servicing\Version"
NET START TRUSTEDINSTALLER
