Decided to give it a go but was surprised to receive a message say it has been blocked by System Administrator!
I'm the ONLY person on this PC & it is NOT part of any Company Network - & I'm setup as Administrator!
Have googled for a possible cause but most of the issues seem to be with a test version of Win 10!
One solution did mention opening the Group Policy Editor (gpedit.msc) but that is NOT found on my PC (presumably because its the Retail version).
Anybody got any ideas?
