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 lands.

How to fix pen issues in Windows 10 KB4093112

Microsoft says there’s one more known issue in this update, although it won’t not be a big deal for most of the users.

  • Press Win key + R and then type winver.

Not only IE, Microsoft Edge is also receiving a lot of improvements and important security fixes. The security patches bundled in this version of Windows 10 are aimed at Internet Explorer, Microsoft Edge, Scripting engine, Windows graphics module and some other Windows components.

    Fix did not work for me, trying to paint with the wacom pen on photoshop still mostly results in scrolling, especially with vertical motions. This has completely fucked up my productivity tbh.
