If you happen to run any version of Microsoft Windows prior to Windows 8 (XP, Vista or Windows 7), 32-bit or 64-bit, even if it was pirated, Microsoft is offering an extremely cheap way to upgrade to a full, legal version of Windows 8 for $15. Technically, the upgrade cost is $40, but if you happened to purchase your PC between June 2, 2012 and January 31, 2013, then Microsoft will let you upgrade for just $15. Usually, an upgrade to a newer version of Microsoft OS costs between $50 to $150, while a full version can cost up to several hundred US dollars. With the introduction of Windows 8, Microsoft wants to move more people away from its outdated Windows XP and Vista operating systems and it wants to make the OS affordable to move up to for a limited amount of time.
If you own a photography business, I would encourage you to stay away from pirated software period – it could cost your business and potentially put you in jail. I have two PCs that I upgraded from Windows 7 Pro 64-bit to Windows 8 Pro 64-bit. One PC was an older machine, so I could only upgrade it with the $40 upgrade promotion. A newer PC that I bought this summer though already had Windows 7, so I was able to purchase Windows 8 Pro for just $15 for that one.
