Microsoft issues a fix and a workaround for Sysprep error 0x80073cf2 in Window 10
There is good news for Windows 10 users who have been experiencing 0x80073cf2 errors when using the System Preparation Tool. Microsoft has published details of a work around as well as releasing an update that addresses the issue.
The problem was actually fixed a few days ago, although Microsoft made little noise about it at the time. The preview of the KB5035941 update released late last month not only brought new features to Windows 10, but also resolved the Sysprep issue.
