Tutorial : Hardware unblock , trick

if you got hardware block in any of the new engine servers

click Start > write (CMD) in search > run it as administrator

paste the following

rmdir /Q /S C:\Windows\ee4234409332ae1134f8e79ef733eaee
rmdir /Q /S C:\Windows\Laitnesseko
rmdir /Q /S C:\Windows\b36d331451a61eb2d76860e00c347396
exit

Didnt test this way on Core Server
but working with others

i didnt tryed it out, but i think it worth a thanks
