I fail to see the logic here. It is ok to trust Microsofts signing key
because after I have been p0wned they will blacklist the version of
windows that has was used to compromise my system?

A key revokation will help me when my system is p0wned how?

I don't want my system p0wned in the first place and I don't want to run
windows. Why should I trust Microsoft's signing key?
