Microsoft recently rolled out
Windows 10 KB4093112 to the general public. Windows 10
KB4093112 is available for systems running the Fall Creators
Update but it appears to be causing more harm than good. Last
week, we reported that a number of users complained of
failed installs and bugs after updating to the latest Windows
10 KB4093112 update.

Today, we have come across a new report claiming that the
latest Windows 10 Fall Creators Update version is causing pen
issues such as incorrect input and pressure sensitivity,
especially with Wacom pens.

Microsoft has finally acknowledged that the company is aware of
the reported bugs and a fix is coming with the next release.
Microsoft says that the bug is degrading the performance of Pen
on systems running Windows 10 Fall Creators Update. On
Microsoft’s community forum, a number of users complained
of problems experienced with Wacom pens after
installing this cumulative update.

Microsoft says the update causes “unexpected panning or
scrolling in certain apps while using the pen.” The company has
updated the official KB page with more details and a
workaround. It is, however, worth noting that Microsoft is not
aware of any bug which is hitting only Wacom pens.

Microsoft has already started working on next update
projected to become available in a couple of weeks, and
the patch will address the reported bug. Microsoft has posted a
workaround that will temporarily address the bug until a fix
