Increasing RAM used in XP mode (Virtual PC)

Hello,
My config is Windows 7 Ultimate 32-bit, Intel i5 760, 2GB DDR3 RAM, 512 MB Graphics Card (Nvidia GeForce 8400)

I can't seem to increase the RAM used in XP mode. It is greyed out. Please help...

Just read the text. It's saying that you must shut down your virtual machine before doing any changes there.

You need to change the machine parameters BEFORE you launch it.

It says that available memory is 1,495 MB ....so will there be any harm if i use all of it ??

Virtual PC needs at least 0.5 GB (512 MB) RAM to be left to host to be able to run a virtual machine, so the available RAM to assign to a virtual machine is total RAM of your host minus 0.5 GB. Your screenshot shows the maximum you can assign to virtual machine is 1,495 MB, meaning you have a total of 2 GB of RAM on your host.

If you assign the full available amount to virtual machine, it leaves that said 0.5 GB to host, which is really little, making running virtual machine a real PITA. A recommend a good compromise, assigning 1 GB to virtual machine, leaving 1 GB to host.
