In addition to systeminfo there is also wmic qfe

Example:

wmic qfe get hotfixid | find "KB99999"
wmic qfe | find "KB99999"

There is also update.exe

Or from powershell, just adjust it for your needs:

Get-WmiObject -query 'select * from win32_quickfixengineering' | foreach {$_.hotfixid}

PowerShell 2.0 contains the get-hotfix cmdlet, which is an easy way to check if a given hotfix is installed on the local computer or a remote computer. An example of the basic syntax is

get-hotfix -id KB974332

run "systeminfo" in a CMD window and it will pull back a load of statistics about your system including what patches are installed.

Some other possibilities: Grep %windir%\Windowsupdate.log for the KB number. Or use reg.exe to export the corresponding install keys.

wmic qfe list /format:htable>C:\PatchList%Computername%.html

Above command will give the output in html format.

As someone asked about using wmic at a PowerShell prompt, just use Select-String (or sls).

wmic qfe get hotfixid | sls "KB99999"
