I just use the device manager to diable the web cam and microphone.
All you need.
Also use Wireless Auto-Off to disable your NIC's with PC shutdown so they can't be magic packet or accessed in sleep mode. If you install Wireless Auto-Off, it works for wired if you make an 'include.txt' file with the name of your wired NIC. Then set your machine for true-shutdown, not hybrid and it will kill your NIC at the device level while the machine is shutdown. On reboot just click the icon to enable the NIC.
Interestingly, the developer of Wireless Auto-Off said a few years ago govt. employees started buying it in huge numbers. Thousands and thousands of copies.. The suspicion is, it was around the time they developed technology to access sleeping NIC's on systems and wanted this program to protect their own systems!
