Show All Windows Updates Applied to a Computer

Use the following to create a searchable list of all Windows Patches currently installed. This is useful when trying to identify if a specific patch is already installed.

*This log can be reliably used only to retrieve updates for Windows OS itself and its components (such asWindows Internet Explorer (IE) or Windows Server roles and features). This will not list updates for any non-inbox software (such as Microsoft Office or Exchange Server).

Note: This will create the hotfixes.txt file in the directory that Command Prompt is currently listed in.

1. Open Command Prompt.
2. Type wmic qfe list full /format:list > hotfixes.txt
3. Type start notepad hotfixes.htm

Use Ctrl + F to search the exported list of installed patches.
