Description:
running the installer it throws a dialogue asking for permission to stop running processes.  Today that was explorer.exe and searchhost.exe

Searchhost is not a user initiated programme.  It has no UI.  There is nowt I can do about it.

The upshot is I have to reboot after an update.

Steps to Reproduce:
1.run installer
2.installer gives a list of things it wants to close
3. tell it to go ahead


Actual Results:
4. it says it cannot close searchhost.exe so I need to reboot after installing

Expected Results:
4. it closes searchhost.exe and finishes the install


Reproducible: Always


User Profile Reset: No

Additional Info:
I cannot understand why it needs to close searchhost.exe, which is a service.  Come to that, why does it ask to close file explorer?  that seems a bit over the top
