I have had a recurring problem with Microsoft over many years. I can't decide whether they are one of the most stupid or arrogant companies going. I suspect it's a bit of both.
One of my clients has a number of DELL PCs with Office 2013 pre-installed. You don't get any software media, just a license key as the software is already on the disk.
That's fine until the disk dies and you have to reinstall Office. Now this should be easy - download the software and enter the license key - wrong! Can't do it for Office Home and Business. Or if you can it's not obvious or easy. You can buy another copy of course or have a trial for a different version....
So how does my client get his Office back?
As it happens I had to buy a copy of Office 2013 for one of their other PCs and saved a link which automatically downloads and installs the software. Unfortunately, this works but doesn't give you the option to enter a different license key so now it won't active - for goodness sake! Who thinks up this c**p!?!!
Why do they make it so difficult for clients who have genuinely bought the software?
