Microsoft Windows 10 latest update 1803 is causing Remote APP to work slow. It also affects right mouse click.

UPDATE (06/13/2018): With the release of the June Microsoft updates, and we believe it would be specifically update KB4284835 the issue that we had previously fixed with the patch in this article will get broken again, and will result in the following message:



Microsoft is aware of this problem, and is working on a fix, with an approximate ETA of End of June 2018, and will tentatively be under the following KB: KB4284848

How to check the version of your windows 10

Click on Start --> Type Winver and hit enter


Hold the windows key and press R, this will open the Run window, simply type Winver and hit enter

The second line will show the version number as highlighted below

If you see the version number as 1803 then you have the affected version.

Turn Off Windows Updates (Temporarily)

Until Microsoft releases a working patch to resolve this problem, you can turn off Windows updates on your workstations, or block the 1803 from installing.

If your organization is not domain joined, and patching cannot be controlled centrally, you can install a small utility on your workstations, which will allow the workstation to prevent updating until further action. Please see and download the Rizonesoft Windows 10 Update Switch
