How to determine if a specific KB Windows update has been applied to your computer
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.
- Launch Windows Update
- Click on View your update history
- Search the update history to see if the desired update is installed.
Second way – Use DISM.exe.
- Launch the Command Prompt with administrative privileges.
- 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
- 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.
Third way – Use SYSTEMINFO.exe.
- Launch the Command Prompt with administrative privileges.
- 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 SYSTEMINFO.exe
- 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 SYSTEMINFO.exe | 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.
Hope this helps you determine if a specific update is installed on your computer or not.
Until next time, RIDE SAFE!
