My laptop is Acer EXtensa 5620Z purchased within 2 years with Vista Home Basic installed. I wish to try out Windows 7. Are there any expenses involved in the change over please ?

You would not be entitled to a free upgrade but you can buy either an upgrade edition or a fresh OEM copy.

Upgrade will install over the top of your current and may be the simplest way of using it. OEM would be a fresh install.

Neither of witch would really let you "test out Windows 7" though, it would be an actual new Operating system.

I would recommend, if you know about virtualisation, you install Microsoft Virtual PC 2007 and a Windows 7 VHD. This will let you test Windows 7 from within Windows Vista.

Also, if you have a MSDN or Technet Subscription, you may be able to get Windows 7 for free.

No, Benedict can't buy an "OEM" copy (legally), because no such version exists for his computer. He can buy a retail copy. Before installing, use the Windows 7 Upgrade Advisor (…) to be sure your system can run that OS. – CarlF Dec 13 '09 at 16:12
The licence has changed a lot in recent years - the copy is just another commodity and he can buy it as any other good or service as long as it is fully boxed. – William Hilsum Dec 13 '09 at 16:37
