Microsoft is one step closer to releasing the Windows 10 April 2019 Update after game developers issue fixes for an anti-cheat bug that has been plaguing Windows 10 insider builds for some time. The bug has been causing Windows machines to crash with Green Screen of Death (GSOD) errors. At this point, there is still one more bug related to X-Fi sound cards that Microsoft needs to resolve before pushing the next feature update out. The latest Windows 10 Insider Build 18865 from the 20H1 branch indicates that a resolution is in sight.
