    Hello! Roll back is not showing up for me, https://www.screencast.com/t/9oIa6jKeXzX

      Hi, Barb. To get the previous version or the latest version of your driver, you can choose to download from your display adapter manufacturer’s website as we mentioned in the article. For some reasons, Microsoft might not detect the update for you, thus you need to update the driver manually.If you want to save time, you can take a try on Driver Easy.
