German blog reader Sebastian noticed that the updates are offered again at WSUS, so he left a comment.

WSUS today announced that KB4088875, KB4088878 and KB408888881 have been revised.

But nothing has changed in the KB article? Bugs still present.

Who has the latest information?

I then checked the Microsoft Update Catalog and found the Windows Update KB4090450 with release date April 4, 2018. 

Update KB4090450

The updates are described in the following KB articles at Microsoft, and the revision date has been adjusted. I once compared my old descriptions with the current KB articles on the updates as well as old versions by wayback machine. The following seems to have changed – hope I haven’t overlooked anything.

I haven’t found any details of what has been revised here. However, since this is a Spectre V2 patch, it could be that the microcode has been updated for additional CPUs.
