Windows has a built-in feature for this

1: Windows Sandbox

2: Hyper-V

If you have 10 or 11 Pro, you should have these features. If not, there's always

3: Oracle Virtualbox

4: VMware Player

For 2, 3, 4, Get Windows 11 IoT Edition to install in the VM

Windows 11 is sketchy software

Personally I run VMware with windows on it.

This VM is disconnected from internet access and put on a separate VLAN on my network but has access to one share folder on my NAS.

Its overkill but fits my needs when I want to roll back the VM or save multiple sessions of it.

Windows sandbox like everyone else is saying is a great answer, but bear in mind if you’re sufficiently paranoid or security conscious that many, many exploits exist to escape VMs and sandboxes. Esxi and cell phones pretty much made that happen.

Keeping a cheap old computer to run weird bullshit on isn’t a terrible choice if you’re truly worried about it.

Virtualbox is free. I hate it, but it definitely works at no cost. VMware Workstation is also free.

Edit: without double-checking to make sure I'm saying it correctly, you probably want to avoid a bridged network and assign one of the other types of network adapters for separation of network devices, but you'll have to search the terminology to find details.

Replace the symlinks in the c/users/ directory with directories. And sandbox wine.

Edit: oops, on Windows. Is sandboxie still a thing?

VirtualBox or any other hypervisor is good choice but keep in mind that some malware can escape VMs. Check your threat model and keep everything upto date.

Windows literally has a VM build in for this purpose.

Called Windows Sandbox.

The safest cheap option is to buy a used old laptop, and run it on a VM there. Using a VPN over someone else's wifi.

What software?

Anyway you can use QEMU https://computernewb.com/wiki/QEMU/Guests/Windows_11 or rent a VPS for the duration of your testing, assuming there is hardware related.

If running Linux on decent Hardware, try Winboat. Easiest way imho

Windows sandbox is easy.

Why not run a vm? Nevermind i forgot windows things. What about an alt for the software

Alternative: install Proxmox on the hardware. Then install all the OSes you want to run on top of that.
