Multiple workspaces on one PC?

Question

Work organization

Greetings to all, tell me, I want to organize several workspaces on one PC.
On one work, the other "home PC" and the third various programs where the antivirus will be disabled.
The question is how best to implement it.
The most obvious way is to install 2 Windows, but then there will be direct access to the file system from one to the other, which is unsafe.
Second, if you install another OS on VirtualBox, then performance will drop.

What life hacks do you know about this issue?

Answer 1

Well, like this or like this.
Or so .
And you can also take substances, get hardware with support for forwarding pci-e devices, buy two vidyuhi, put a hypervisor to your liking with the ability to forward cards to virtual machines, forward usb mice / keyboards after them and thus get two / or more jobs.
For good, just stop suffering from garbage, separate work and home user profiles using regular means, and virtualization for experiments with the antivirus turned off.

Answer 2

Get two / three users and rejoice. It is also desirable to leave admin rights to only one of them. This is the simplest and most resource-saving option.
Of course, it won't be exactly the way you want it to be. The option you described is only possible either on different PCs or on virtual machines. But these options have their own side effects, as you yourself understand.
So you have to compromise.

Answer 3

but then there will be direct access to the file system from one to another

this is all configurable, through rights and as an option, literally split into sections and hide them in 'disk management'

Answer 4

I have Windows on the host and Linux in Vmware Player (free for non-commercial use). The performance is more than enough to do development on Linux (IDEA, docker and all that stuff). I have not tried to run games in Linux (and most likely they will not work). An SSD is desirable (well, it is highly desirable in 2022 anyway). In my opinion, if you want maximum isolation, then this is the best option.
