When Microsoft issued the latest build of Windows 10, build 10049, to Windows Insiders it had two known issues which are addressed with these two patches



From Supersite for Windows:

As we have heard from our Ring Master, Gabe Aul, on a regular basis one of the risks associated with getting faster builds is they will come with some challenges.

Some of those will be known and others will be unknown and hopefully discovered by Windows Insiders as they test the latest Windows 10 Technical Preview builds.

Two such issues were known in build 10049 and now the patches released today fix those very same issues as detailed below
