Manage Updates on a Windows Server Core System

Windows Server Core saves on system resources, however some familiar features on the  full Windows Server install are not as obvious on Server Core. For performing and managing updates on a Server Core installation you have the below options:

  • To install a Windows update : At the command prompt enter wusa <update>.msu /quiet
  • To list the Windows updates already installed : At the command prompt enter systeminfo
  • To remove a Windows update :
    1.  At the command prompt enter expand /f:* <update>.msu c:\test
    2.  Go to c:\test\ and then open <update>.xml using a text editor
    3.  In <update>.xml, replace Install with Remove and then save the file
    4.  At the command prompt enter pkgmgr /n:<update>.xml
  • Configure automatic Windows updates :
    – To see the current Windows update setting, enter: cscript scregedit.wsf /AU /v
    – To see the automatic Windows updates, enter: cscript scregedit.wsf /AU /4
    – To disable automatic Windows updates, enter: cscript scregedit.wsf /AU /1
