Solution 3: Check for device updates
Windows 10
If you use automatic updating, you don't need to check for important and recommended updates. Windows Update checks for these updates and installs them when they're ready.
If you don't use automatic updating, you should check for updates yourself at least once a week. We usually release important updates once a month. However, updates could be released at any time.
No matter what your settings are, some updates aren't installed automatically. These include optional updates and updates that require you to accept new Terms of Use. When these updates are available, Windows Update will let you know that they're ready to be installed.
  1. Select the Start button. In the search box, type Update, and then select Windows Update in the list of results.
  2. In the left pane, select Check for updates, and then wait while Windows looks for the latest updates for your computer.
  3. If any updates are found, select Install updates.
    Note You might need to restart your device to finish installing some updates. Save and close all your files and apps before you restart so you don't lose anything.

  2. Select Check now, and then wait while Windows looks for the latest updates for your device.
  3. If updates are found, select Install updates.
  4. Read and accept the license terms, and then select Finish if necessary.
    Note You might need to restart your device to finish installing some updates. Save and close all your files and apps before you restart so you don't lose anything.
