I want Windows software that blocks everything except one application of your choice. I want this for gaming. Oftentimes when gaming, there's like 5 or more other applications randomly using the internet without my concern, I believe I already disabled every update option on my apps... I noticed this is bad for my ping. I don't want to do this one by one via firewall.
As fa as I know QubesOS is the only one that can allows you to do so
