15Gb is recommended
/\_______don't think that by "memory" the question is talking about harddrive space, which is what this answer appears to be attempting to answer. By memory, typically one is referring to RAM. As far as ram is concerned, I would recommend at least 512MB. To really be able to do multiple tab browsing with videos, music and the like I would recommend 1-2GB. If you're talking about wanting to watch blu-ray video at 1080p or games 4GB+

Virtual Memory Manager
To do this, you have to tell Windows to put the file there. First go to System in the Control Panel. Or you can hold down the Windows key and press Pause as a shortcut to get there from anywhere. Then go to Advanced and to Performance Settings. In there, open the Advanced Tab. Then select Change under Virtual Memory. Then you tell it you want none on the C: drive and the desired custom size on D: drive. One good strategy is to choose the recommended maximum and using that as the minimum size too. The recommended size that Windows suggests varies with the version of Windows. Most prefer the same size swap file as you have physical memory. So if you have 4 Gb of memory, a 4 Gb swap file is recommended. Other versions like Windows 7 prefer 1.5 times the memory, so if you have 12 Gb, it will recommend an 18 Gb swap file.
Older .exe files are not going to work with windows 7. You can use Virtual PC to run applications working under windows xp but not working under windows 7.
Physical memory, as with all computer resources, is managed by the system. Applications access virtual memory exclusively, no exceptions, ever. Physical memory (RAM), the pagefile, and many other files on the hardisk make up the virtual memory system. This system has been extensively researched and tested and it usually performs very well. Virtual memory is VERY complex, and the designers understand it better than you do.
You hit the Windows start button, click computer, and then it should say your memory size under the (C:) drive.
Yes and no. Linux will not run Windows applications by itself, however, there are ample tools written for Linux that permit you to run Windows applications on Linux. The open-source WINE software will run a majority of Windows software on Linux. You can even configure Linux to automatically recognize Windows applications and use WINE to run them. Alternatively, there's a wide variety of virtual machine products that permit you to run the Windows operating system as an application under Linux, and, in turn, any Windows applications inside the Windows virtual environment. Finally, some "Windows applications" are written in .Net or Java and can be run directly under Linux using mono and java respectively (albeit, some .Net applications will not yet run under mono).
Install program
you would select Add or Remove programs in the control panel to install applications and software.
Virtual memory is determined by 2 factors. First, the amount of free hard drive space available on your hard drive. Secondly, it is determined by your virtual memory settings under Windows properties. Assuming you have not changed your Windows default settings, then every ounce of free harddrive space IS virtual memory.
If you have windows xp it should do an autoplay and then after you select what to do with it, it will list it under my computer- devices with removable storage.
