A very good hotline is the most important part of a software company (if you really on customer satisfaction).
I update my Mainboard, CPU, RAM. Everything was ok...
After that I copied my VM from a single M.2 to a Raid-Stripe-Set of M.2's.
A suddenly: Office wants activation a Windows, too
First, try on the Microsoft Hotline. A very grumpy man: Your Windows Key is not Valid ( I've used this key since upgraded from Windows 8 ). You have to buy a new Key. Have a nice day. Tuuuuuut. He just hangs up.
Second try: A not so grumpy man - more helpfully - No problem Sir, please gibe my the 8 Digits from these 8 groups. Two tries. and then the same answer: You have to buy a new Key. Have a good day. By By.
And now - Windows wants a new key and office, too
Amazon: New Windows Key for 1,48€ - yes under 2€ - the hotline cost was higher!
eBay: New Office Key for 7,25€ - upgraded my office from 2016 to 2019... Nice, now everything is working.
