Me too. 

This approach - DOES. NOT. WORK - 

So, please, please cease suggesting this, advisors. If that's all the advice you can give us, how about re-engineering the update and rolling out a version that works instead?

You are right, the person who wrote that must not understand Windows 10 S mode.

Microsoft is probably working on a fix even though there seems to be little info on the problem.  However, the problem is not really an issue on S mode machines.  The message you'll find regarding this issue is at this link: 

• Win10-S mode is not supported, there is no added value of running MSRT on this platform. Any install failures of attempting to install the package can be safely ignored.

The error message is indeed annoying and really should not happen.  Microsoft should fix stuff like this quickly, even if it is harmless.  Users do not appreciate message that show an update failed because it makes them feel as if something is wrong.  In this particular case, when this error occurs on a S mode machine, it can be ignored (according to the above note at that Microsoft link).

According to the following support article Remove specific prevalent malware with Windows Malicious Software Removal Tool

Win10-S mode is not supported, there is no added value of running MSRT on this platform. Any install failures of attempting to install the package can be safely ignored.

So it safe to ignore the error. However it would be nice if this package would not be installed at all, if it's irrelevant . The error message is really confusing ..

keep getting this message on windows update even after clicking retry several times,

There were problems installing some updates, but we'll try again later.

For those running in S mode and receiving the error, I found this message (see below) regarding the failed MSRT install package.  It is obviously something Microsoft is working on.

You can also get to the explanation by going into your Windows Update settings and clicking on "View Update History", find the KB number that is failing, then click on the link associated with your failed update.  You'll see a note part way down the page that says: 

• Win10-S mode is not supported, there is no added value of running MSRT on this platform. Any install failures of attempting to install the package can be safely ignored.

The error message is indeed annoying; Microsoft should fix stuff like this quickly, even if it is harmless.

Microsoft Fix this please?

Also, Windows is recognizing a peripheral scanner (from Brother) as a storage and won't install the driver and can't locate on '+ new device'.

I would download it from Brother website but Windows S won't allow it (also, there is no CD ROM drive on this laptop).
