I heard that in Sp1, if you run a pirated copy of vista, you can still use your pc, as long as you can put up with a black background and obvious signs saying windows is not genuine. Does that mean i can download a pirated copy of vista ultimate off the internet, and run it in a dual boot/virtual machine, and still be able to use it without being charged with piracy or any of that other microsoft crap? Thanks for those who can help!!

For : the practical issue here is licensing and safety, not just whether the OS will show warnings. and rightly raised concerns; the posts so far do not cover how to get a legal, safe test environment or what virtualization means for licensing.

Every installed copy of Windows — physical or virtual — needs a valid license under its EULA. Retail, OEM and volume licenses have different rules (transferability, virtualization rights, etc.). Using the same product key in multiple VMs will trigger activation/validation problems and does not make extra instances legal. For legitimate testing, Microsoft has historically provided evaluation images and subscriber downloads (MSDN/Visual Studio subscriptions) that avoid licensing questions.

Pirated ISOs are frequently modified and often contain malware or activation tools that compromise security. Running an untrusted image in a VM still risks the host when integration features (shared folders, clipboard, bridged networking, guest additions) are enabled. If an image must be inspected for safety, keep the VM isolated (host‑only or NAT, no shared folders), take a snapshot, and avoid enabling guest integration until the VM is cleaned.

To check activation/license details on an installed copy (use an elevated Command Prompt):

cscript %windir%\system32\slmgr.vbs /dlv
cscript %windir%\system32\slmgr.vbs /xpr

Safer options: obtain an official evaluation or MSDN image for testing, buy a low‑cost retail/OEM license for regular use, or use a free OS for experimentation. For business use, consult Volume Licensing/Product Use Rights to understand how many VM instances each license permits. ’s point about conscience aside, there are legal, secure, and low‑cost ways to achieve the same goals without using untrusted copies.

No the only reason Microsoft no longer disable your PC if you have a pirated copy of Vista is that they were having a lot of false positives for piracy, and locking down a lot of genuine copies. If you install a pirated copy and are caught you are still subject to the same charges as before. Even if it is in a virtual machine.

What does your conscience tell you?

yeah, the only difference is it wont completely lock it out anymore. Its still against the law though.
