Known Issues

There has been an issue with older versions of anti-cheat software used with games where after updating to the latest 19H1 Insider Preview builds may cause PCs to experience crashes. We are working with partners on getting their software updated with a fix, and most games have released patches to prevent PCs from experiencing this issue. To minimize the chance of running into this issue, please make sure you are running the latest version of your games before attempting to update the operating system. We are also working with anti-cheat and game developers to resolve similar issues that may arise with the 20H1 Insider Preview builds, and will work to minimize the likelihood of these issues in the future.
Some Realtek SD card readers are not functioning properly. We are investigating the issue.
Creative X-Fi sound cards are not functioning properly. Creative has released updated drivers for some affected X-Fi sound cards. Please refer to Creative’s website for details on your particular hardware and any available updates.
UPDATE: We have received feedback from some Insiders that they are seeing a 0xca00a000 download error for Build 18875. We are investigating. Please upvote feeback item https://aka.ms/AA4qqb2 if you have experienced this issue.
