VMs (Hyper-V, VMware, VirtualBox) are the natural way to isolate test environments. But for performance-sensitive tests — game stress tests, GPU benchmarks, native driver QA — VMs are too slow.
Testing on a single physical PC with HWID change between runs gives near-zero overhead while still isolating identifier state. License servers and analytics see each run as a separate "new machine."
The trade-off: state lives on disk, not in a VM image. Cleanup between runs requires extra discipline — typically scripted via PowerShell + HWIDChanger CLI.
We support QA teams with bulk HWID-change scenarios, profile import/export, and Jenkins/GitLab integration. Get in touch if you want a demo.
