If you want to run Windows XP Mode from your Windows 7 desktop, then you processor (CPU) must support hardware virtualization with AMD-V or Intel VT turned on in BIOS.
Windows XP Mode is designed to provide small business and mid-sized businesses running Windows 7 Professional (or higher) the ability to run Windows XP productivity applications that may not be compatible with Windows 7.

To check, if you can use Windows 7 XP Mode, just use a simple program ‘SecurAble’ which will tell you this easily. SecurAble probes the system’s processor to determine the presence, absence and operational status of three modern processor features:
- 64-bit instruction extensions,
- Hardware support for detecting and preventing
the execution of code in program data areas, and - Hardware support for system resource “virtualization.”
Just run this standalone program and check for the 3rd entry ‘Hardware Virtualization’ is supported or not. If it says ‘No’ then you’re bit unlucky like me.
