Microsoft announced yesterday it has finalised the code for Windows 7's XP Mode.

The mode, which was announced back in April, will allow XP programs to run in Redmond's upcoming operating system.

XP Mode is to be released on 22 October, the same day Windows 7 is to be released to the general public.

Microsoft hopes XP Mode will combat any compatibility problems users have when upgrading to the latest version of the operating system - one of the major gripes users had with Microsoft Vista.
