APM file and registry key date check 8 days old

Hello Guys,

I need to have an APM box and maybe iRule for VPN connection to check windows file presence and registry key, if date is older than 8 days users cannot access and it goes to quarantena forcing compliance , if newver user can access to network. I see something with windows registry check value to fetch and get to variable to manipolate with iRule, but I don't understand exactly how to do it.

Any advices?

Thanks so much
