Microsoft has released Windows 10 Insider Preview Build 18898 to Insiders in the Fast ring. This build includes a new feature in the Task Manager performance tab that shows the drive type of installed disks as well as fixes for crashes in Explorer and Explorer DWM. Windows 10 will now show the type of drives that are installed in your computer. Microsoft is working with partners on getting their software updated with a fix, and most games have released patches to prevent PCs from experiencing this issue. We fixed an issue resulting in a high hitting DWM crash in recent builds.
