catilley1092 - Welcome to the Windows 7 Forum! I am sure you'll find it a rewarding experience as much as I have.
You won't have to many issues getting used to Windows 7. It's extremely user friendly and there are many good guides available out on the web to help you.
Go to Paul Thurrott's website here:

for good info and tips. In addition, there are several good guides and articles here at Windows 7 Forums.
Windows 7 x64 is a good OS, you'll like it! If you ever decide to add another 2GB of RAM it will really help out.
Have fun, enjoy the best version of Windows ever! I am serious because I used Windows XP Pro for years, skipped Vista entirely and have had no problems migrating to 7.
