I am running a KVM virtual machine through QEMU with VFIO based GPU passthrough. My only installs on the system are Roblox Player / Roblox Studio, Discord, ShareX, Looking Glass (for screen recording), AMD GPU drivers. While sitting with one Firefox tab and Task Manager tab open, I am using 7.7 GB of memory as marked through the committed section. Before I cleared up files to make room for having a page file, whenever the 7.7 GB of memory reached the amount of memory set for the VM, it would result in system freezes inside of the VM. This is also after the usage of utilities such as Windows 10 Debloater.
Additionally, my Linux installation (discounting the /home folder, /var (qemu disks,)) and other files are only taking up 75 GB of space, despite the massive amount of software that I have been too lazy to remove from my system. Meanwhile, my Windows 10 VM is sitting at 39.7 GB of storage in usage.
Windows is most definitely bloated, and for myself and others, this usage of system resources is still a hassle to deal with. There is no replacement that can be made for proper Linux support, and either way, all of us are still inconvenienced for choosing an option that we see as better.
