What You Get With Windows 7 Professional:
Windows 7 Professional gives you everything from the Home Premium Edition, and adds a number of important upgrades. They include Windows XP Mode, so that your computer can run all your legacy Windows XP programs -- no Vista-like worries about whether they'll run in Windows 7. Windows 7 Professional computers can also join a domain, making them an excellent choice for use in a business setting.
What Windows 7 Professional Does Not Have:
Windows 7 Professional Edition lacks BitLocker technology, which lets you encrypt hard drives for increased security. This can be especially valuable when you have sensitive information stored on portable hard drives like a thumb or USB drive.
Why Choose Windows 7 Professional Edition:
Power users, who have greater needs than the average user, can make good use of Windows 7 Professional. Also, those who don't want to buy a third-party backup solution may want to opt for this version, since it has network backup built in. If you have many old programs that you rely on, this is also a good choice, since Windows XP Mode will make running those programs possible. This is the minimum required version for most businesses, since it can join a domain, unlike Windows 7 Home Premium.
