For what it's worth - you can also stop services with a batch file (or a .cmd file) such as:
net stop "windows update"
net stop "Windows Firewall"
net stop "acronis scheduler2 service"
net stop "computer browser"
net stop "ike and authip ipsec keying modules"
net stop "ip helper"
net stop "ipsec policy agent"
net stop "tcp/ip netbios helper"
net stop "WinHTTP Web Proxy Auto-Discovery Service"
net stop "Network List Service"
net stop "Network Location Awareness"
net stop "dhcp client"
net stop "dns client"
(spell the names exactly right)
Then when you're not recording - another batch file does the opposite "net start..." in the opposite order.
You can do a lot in a batch file - and google is very helpful (so are we here on the forum) - and it's easier than disabling services etc one by one. Just sayin...
