windows updates august 2020

It is recommended that you wait with the installation of these updates as they may introduce bugs and other issues. If you have to install them, we advise that you create a system backup before you install the updates so that you may restore the system should issues arise that cannot be fixed at that point in time.

The Windows updates are available via Windows Updates, WSUS and other patch management systems. Home users may check for the updates on their devices to download and install them right away.

  1. Open the Start Menu of the Windows operating system, type Windows Update and select the result.
  2. Select check for updates in the application that opens. Updates may be installed automatically when they are found or offered by Windows; this depends on the operating system and version that is used, and update settings.
