Get the latest updates and drivers
Use Windows Update to install the latest updates and drivers (Microsoft's 'Automatically get recommended drivers and updates for your hardware' page explains how).
Update a driver by hand
If the blue screen points to a particular hardware device, update that device's driver yourself (see Microsoft's 'Update drivers through Device Manager in Windows' page). Microsoft recommends trying Windows Update first.
If you download a driver yourself, get it only from the device maker's official website and make sure it matches your version of Windows (Microsoft's 'Update drivers through Device Manager in Windows' page).
System Restore or Startup Repair
Changes the Windows installationIf something changed recently - updates, an updated driver or a new app - use a Windows restore or repair option (see 'Recovery options in Windows').
Microsoft advises: Back up your important files before you start. If BitLocker is on, you'll need your BitLocker recovery key for most recovery options in Windows RE. (Recovery options in Windows)
