Rat
Not bored. Never bored.,
It is. Running Endpoint Security, managed by Security Centre. There are recent updates that mean it will install, which is quicker than they managed for Windows 8, but they are not without the sort of problems that we wouldn't want to have on production machines, and it was months last time before they were ironed out.I upgraded my Win 8.1 Pro laptop this afternoon.
I'm running Kaspersky. After Win 10 booted there was a message from Kaspersky that I managed to miss. Anyway, I fired it up and clicked the update button because it said it needed updating.
Within a couple of minutes all was well.
I'm running a 3-PC license aimed at households, so maybe it's different for an Enterprise system.
