FortiClient EMS Zero-Trust Tags

Dears,

I hope you all are doing very well these days,

My customer has a requirement that I couldn't find a solution for it,

Basically, the customer wants to Check for the Windows KB version if it is installed or not in a certain PC before allowing the PC in the network, this should be done of course in FortiEMS (Zero-Trust Tags) with FortiGate,

I can check for Windows version, release, etc.. using Registry keys, but I couldn't find a way to check for certain KB release if it is installed or not,

Can anybody please help me on this,

I really appreciate your support guys,

Thanks,
