Hi Neville,

Servicing stack updates are not listed in the Update History. A workaround is to install the newest cumulative update, which requires your device to have the latest servicing stack update Installed. If it says the update is not applicable provided it is for
your version and architecture, it probably would mean you do not have the latest SSU.

Hope that helps.

 

July 2020 servicing stack update (SSU) error "You need to provide Administrator permission" [KB4566425]

With regard to the two enumerated errors:

1. The recommendation to install SSU's before any other updates is because the SSU is designed to update
   the updating software itself. However, experience with the previous 2019 & 2020 SSU's suggests that it is generally not detrimental to install an SSU after other regular updates that the Windows Update Client recommended to be installed before it
   advised of that SSU's availability.
   
   Do not bother to uninstall any regular updates before installing the SSU:
   if the other, regular updates were already correctly installed, then reinstalling them again after the SSU has been installed should not produce a different effect.
   
   It may be that specific 'regular' updates that actually do
   require the SSU are not released (or not recommended to be installed by the Windows Update client) until a few weeks after the relevant SSU is released (and recommended to be installed).
2. Based on experience with the 2019 & 2020 SSU's, although installation with the usual Windows Update tool doesn't work the way it's supposed to, installation should still be possible using the
   
   Microsoft Update Catalog — in which case the user must be careful to manually select the appropriate download for their Windows version.
   

Some additional
documentation on Servicing Stack Updates has been published by Microsoft. A couple of interesting remarks are:

• it's unnecessary to go back and install old SSU's that you skipped (just install the newest SSU for your system); and
• after a particular servicing stack update is installed, "it cannot be removed or uninstalled" [although it can be updated by subsequent SSU's, which effectively replaces the entire servicing stack].

Finally, Microsoft also has a
short FAQ on Servicing Stack Updates. There are a couple of interesting points there:

• Failure to install an SSU before installing a 'regular' update to Windows (LCU, Monthly Rollup, or Security-Only update) could potentially cause Windows to fail to start or continue to restart!
  • The FAQ provides advice on what action to take to remedy this, if it has happened to you.
    
  • Although the Windows Update client's strange notification sequence means that an SSU will often be installed after some particular 'regular' updates, that
    doesn't mean it's safe to never install the SSU while continuing to install all future 'regular' updates.
    
• The latest SSU for your device can be found in ADV990001 | Latest Servicing Stack Updates.
