All three of my Windows 10 PCs have encountered a Windows Update error recently. Never had problems before. Odd timing.
One of the recent updates required the recovery partition to be around 750Mb. Many Windows 10 installations have recovery partitions with around 500Mb. Most of the time it is not very difficult to resize this partition but of course users had to do some research to discover what was going on. I assume this idiocy has been corrected by now, but I don't know because the problem was fixed when I resized my recovery partitions. What would Windows be without this type of excitement?
