ALERT: Windows 10 January 2018 Security Update KB4056892
On Windows 10, the
January 2018 Cumulative Security Rollup KB4056892 has caused connectivity issues between ASCOM components. This was caused by a change in security that affected an obscure feature that was introduced for an astronomy product many years ago. You can find
more information and
instructions on how to manually make the adjustments needed to restore connectivity published by one of our members.
We are aware that the security change affects some of the ASCOM Platform simulator components, as well as requiring changes in the tools for new driver developers. At present we are not recommending driver developers make this change to their existing drivers. It is unclear whether Microsoft will reverse this change or not. The release notes do say it is a "known issue" and that it will be addressed in a future release.
We plan to wait for Microsoft's next move, which should be soon as there are other critical issues with this update which will likely cause another one to come out soon. If it turns out that this security change is permanent, we will make the adjustments needed to the Platform and the Developer Tools.
