Microsoft February patches have been relatively benign, for all except those running Windows 8.1.

Since I wrote about the outstanding problems last week, we&ve had a few interesting new developments:Microsoft released the second February cumulative update for Windows 10 version 1809, KB 4482887.

It has three dozen bug fixes, including a fix for the Access95-era Jet database bug, but appears to be quite solid. There a mysterious new &Compatibility update for upgrading to and recovering Windows 10, version 1809: March 1, 2019& KB 4489491that so poorly documented it could do just about anything.

I often wonder how admins with regulatory responsibilities can install stuff like this. The &Access 95 Jet database bug& introduced by this month Win7 and 8.1 Monthly Rollups and Security-only patches now have standalone fixes in the Microsoft Catalog -- KB 4490511 for Win7 and KB 4490512 for Win8.1. I&m seeing reports of bluescreens after installing this month Win 8.1 Monthly Rollup, KB 4487000.

If you&re using Windows 8.1, you should be prepared to roll back the Monthly Rollup. All of this comes in addition to the &Internet Explorer doesn&t understand the backslash& bug I described last week.

@PKCano further admonishes, &Watch out for the KB 4491113 hotfix Cumulative update for IE 11, which can cause additional problems.

Unless you are having that specific problem & and you can&t avoid using IE 11 & avoid the fix.&
