After many months of successful updates, all Windows updates (incl. cumulative updates, security, and definition updates for windows defender) fail with the error code 0x80070015. I had not made any changes to my VM. Just...stopped working, despite repeated attempts over several weeks. Most recent fails are related to Win v1803.
Since then, I have updated to both iOS Mojave 10.14 and Fusion 11. Network adapter is NAT mode. Machine is a late-2012 iMac. Under VM>Settings>RAM, memory set to 2768MB. "Local disk" under Win10 shows ~25GB available. Current version running is Windows Pro 1803, latest update applied 9/12/18.
I confess it's been a while since I mucked around with Fusion settings, so before I go brute-force mucking: suggestions on what causes this fail (in the MojaveWin 10/Fusion 11 era)? What else should I look at? thx
