Windows 10 Compatibility Cookbook: March 23, 2016

Mitigations

• 
  Suitable graphics drivers should be delivered either by DU during the upgrade process or by WU soon after the upgrade completes. OEMs must ensure that the appropriate graphics drivers are included in the system images used for factory installation of Windows 10 on their computers.
  
• 
  After an upgrade, the user can explicitly check Settings \ Windows Update for drivers although this should not be necessary. Users who force a check while a driver is being automatically installed in the background might see a driver installation failure if the automatic installation completes first. This can be ignored.
  
• 
  Users who intend to do a clean install of Windows 10 should obtain the relevant drivers before installing or rely on Windows Update to supply the drivers later, in which case they must ensure that their Internet connection is working.
  
• 
  For computers that receive a coverage driver there is no mitigation for missing functionality. However, this should only happen in cases where the hardware supplier no longer maintains the drivers, i.e. computers that are several years old.
