There may be times when troubleshooting or preparing for an upgrade to determine if a specific KB Windows Update has been applied to a computer.

For instructor-led training, see our Windows 10 classes. For more, see our complete course schedule.

There a couple of solutions.

First use the Windows Update tool.

  1. Launch Windows Update
  2. Click on View your update history

Second way – Use DISM.exe.

  1. Launch the Command Prompt with administrative privileges.

003-kb-update

  1. By typing the following command within your elevated command prompt will get a list of all updates that have been applied to your computer. Search the update history to see if the desired update is installed:

Type dism /online /get-packages

 004-kb-update

  1. You can check for a specific update by piping the output to FINDSTR. Typing the following command within your elevated command prompt will get a list of a specific update has been applied to your computer:

Type dism /online /get-packages | findstr KB2894856  (KB is case sensitive)

Note:  (Replace the KB number with whichever update you are looking for.)   If the update exists there will be a response if not a command prompt will be returned.

005-kb-update

Third way – Use SYSTEMINFO.exe.

Hope this helps you determine if a specific update is installed on your computer or not.
