Next month Microsoft will release the next version of its Windows operating system, Windows 8, and if you recently bought a new PC then you may be entitled to a cheap upgrade.

If you bought a PC running Windows 7 on or after June 2 this year then you’ll have the option of upgrading it to run Windows 8 at launch for just under 15 dollars.

If this sounds like you then you can register for the upgrade now at www.windowsupgradeoffer.com.  If however you have a computer running Windows 7 that isn’t new, the upgrade to Windows 8 will be a little more expensive but possibly only around $40 for most users.
