Windows 7 XP Mode (are there memory limits)

Hello RolfCMeyer,

Thank you for posting to the Microsoft Answers Forum.

I would suggest you review some of the information about XP Mode and Virtual PC.
Running Windows XP Mode requires:
 
1. Windows 7 Professional, Enterprise, or Ultimate editions.
2. A computer capable of hardware virtualization. This means your computer has a central processing unit (CPU) with either Intel-VT or AMD-V virtualization features.
3. Virtualization features turned on in your computer’s basic input/output system (BIOS).
 
To determine whether your computer’s CPU is capable of hardware virtualization, go to the Windows XP Mode and Windows Virtual PC support website and download a utility that can check whether your Intel or AMD CPU is compatible.
 
http://www.microsoft.com/windows/virtual-pc/support/configure-bios.aspx
 
To find your brand of processor so you can download the appropriate utility, click the Start button , right-click Computer, and then click Properties. Under System, next to Processor, you can see what type of CPU you have.
 
Even if your CPU can run Windows XP Mode, you might also need to turn on virtualization settings in your computer’s BIOS. Procedures vary depending on the BIOS manufacturer. For more information, see BIOS: frequently asked questions.

Hope this will give you information you need for your client.

Sincerely,

Okay that helps a bit.  One last question: So is there a limit as to how much the virtual pc of XP Mode will recognize in terms of the memory I want to allocate to it?

Or will programs normally running on a 32 bit os of XP only be able to run on what would XP be normally recognizing?
