Preface: I realize this is a Windows 10 Fast-Ring pre-release build. IMO, the issue should be identified and resolved nonetheless.
After having ESS working reliably on Windows 10 for a good long while, I began experiencing issues getting Windows Updates. The issue exhibits when beginning some download (for example, a Windows Update download), and it will go to some seemingly random % completion and then just hang. In other cases, it appears to complete the download, but the file will be corrupted.
I cleared caches, and followed Microsoft's suggested troubleshooting steps but nothing would clear the issue with Windows Update. It didn't even occur to me that ESS could be the issue until I was updating another product and the while the download appeared to work, the installation kept failing due to corruption of the downloaded file.
While troubleshooting, I turned of all protection and tested, but the issue remained. Finally, in desperation, I completely uninstalled ESS and everything started to magically work again. I'm guessing its HIPS related but I'm not totally sure.
I tried it also with WIn 10 Build 14951 and today with Build14955. The same issue occurs in each of these Fast Ring versions.
I also attempted to use Interactive and Smart detection modes, but even though I received the pop-up and told it to create a permanent rule, the issue still occurs. Only a full uninstall will work-around the issue.
Would love to be able to reinstall and upgrade to V10 if anyone has a way to resolve this.
