There is a privilege escalation vulnerability in the Windows Certificate Dialog allowing an attacker to easily elevate privileges to NT AUTHORITY\SYSTEM, it is documented as CVE-2019-1388.
This is a good video demonstrating the issue: https://www.youtube.com/watch?v=3BQKpPNlTSo in this case they use the hhupd.exe to perform the attack.
Also check out this link from @gentilkiwi about affected versions: https://gist.github.com/gentilkiwi/802c221c0731c06c22bb75650e884e5a
Of course you do not need hhupd to exploit that specific vulnerability in youre next red team engagement, its just easier.
