Microsoft is investigating errors and issues affecting Windows 10 devices with certain versions of Conexant or Synaptics audio device drivers, Microsoft IME (Input Method Editor), and third-party drivers. Microsoft is currently rolling out Windows 10 20H2 (aka the October 2020 Update) to all seekers who check for updates via Settings on devices running Windows 10 1903 or later. Redmond has added two compatibility holds to block Windows 10 2004 and later from being offered to systems with the problematic drivers.
