Upgraded the motherboard on BradsPC to a Z390 to accommodate a 9th generation i5 cpu. The old motherboard wouldn't power up with it.

The actual hardware installation went well. Reactivating Windows 10 was a nightmare. I have a Microsoft digital licence, which I thought meant you didn't need to record the product key. Wrong! Took 3 days to get through the first layer of Microsoft support, who kept on putting me through to the wrong support next level centre. Finally got it done and this time, took note of the product key.
