Weejeem's GWX Sneakware Removal - Notes is reasonably comprehensive, although I would take issue with setting Windows Update to Never check - much better to set it to "check but allow me to choose", or whatever the wording is.
If you really want to eradicate all traces of the Windows 10 malware, do a simple search on C drive - dir /s *GWX*.* and be prepared to take ownership and change permissions on all the files it finds related to "Get Windows X" prior to deleting them.
You may also want to trawl the registry for GWX and remove as necessary - taking ownership and changing permissions are again necessary prerequisites.
It is tedious but immensely satisfying!
