Deactivate Windows Defender / Firewall
If you are running Windows 10 on an isolated VM or retro PC with less than 500MB of memory, you may realize that most of the memory is actually used by Defender and Windows Firewall compononents. There is a way to entirely disable these components and prevent them from loading into memory on boot. This is a terrible thing to do, but the following will save you a few hundred megs in RAM usage.
Warning: You shouldn't continue from here unless you really know what you're doing. Don't do this if you are on a multi-user network or when directly connected to the Internet. Be careful with downloads!
Disable SecurityHealthService
Run „regedit“.
„HKLM\SYSTEM\CurrentControlSet\Services\SecurityHealthService“ Change the parameter for „Start“ from "2“ to "4“.
Careful: This value likes to revert every now and then after feature updates.
