It says Adobe... So there is a component from Adobe in the core windows? Or does the DLL come with a PDF reader installation?

It's needed for displaying Postscript Type 1 fonts. I believe Adobe owns the licensing for everything but it's up to Microsoft to update the Windows 10 DLL.

Then they (Microsoft) should deliver an update that disables this functionality, within the the next three hours.

Then re-enable it when the fix is in.

That'll literally disable half the fonts on the system, in UIs.

I demand to speak to Adobe’s manager!

It's an adobe component in Windows to handle fonts because Adobe controls/controlled a big part of the font ecosystem. At this point I believe the Windows team controls it and can make changes to it, but it's definitely supporting adobe file formats

As pointed out in other threads, it is a Microsoft component that (heavily) forked from purchased Adobe code somewhere around Windows 2000/XP.

Doesn't seem to be. The file (ATMFD.DLL) doesn't exist in a fresh install of Windows 10 1909 enterprise.

It's ATMLIB.DLL on Win10

Thanks. That explains why their mitigation script (the rename one) doesn't work.

Not the same thing. The ATMFD code moved to fontdrvhost.exe, but don't rename that, you'll break your system.
