Today I need to handle an older system… I need to verify if a hotfix is installed in and older AX 2009 system. I found this instruction online (link below): Here is another way to get the list of installed KBs in AX 2009:

1. Start the AOT (Ctrl + D)
2. Go to Classes – SysHotfixManifest and expand it
3. Select a methods and press Ctrl + A to select all methods
4. Right-click and click Add-Ins – Copy – Name
5. Paste into Wordpad (Notepad does not handle the CRs very well)
6. Search for the KB number you want to find

That’s it
