Installing Windows 7 RC
Thank you for helping us test the Windows 7 RC. To help make sure you have a great experience, please read this section before you install the software.

What you need to know before you begin:
If you’ve installed Windows 7 Beta on your PC, you’ll need to back up your data, and do a clean installation of the RC. Then you’ll need to reinstall your programs and restore the files, settings, and other information you want to use for testing.

While we consider this a stable and high-quality pre-release version of Windows, the RC is not the finished product. It could crash your computer or cause you to lose important files or information.

You’re pretty much on your own as you test the software. You need to be comfortable setting up and troubleshooting a PC. If you have a problem, you can find a lot of help from other testers online, but we’re not providing formal tech support. Before installing the software please read these two documents for important information: Things to Know and Release Notes.

IMPORTANT: The RC will expire on June 1, 2010. Starting on March 1, 2010, your PC will begin shutting down every two hours. Windows will notify you two weeks before the bi-hourly shutdowns start. To avoid interruption, you'll need to rebuild your test machine using a valid version of Windows before the software expires. You'll need to rebuild your test PC to replace the OS and reinstall all your programs and data. (To learn more, see Frequently asked questions.)

Things you need to have before you start:
Dedicated test PC: Please don’t test the RC on your primary home or business PC.

Data backup: The information on your PC will not be saved during installation. Back up your PC before you start, and frequently during testing. You can back up files to an external hard disk, a DVD or CD, or a network folder. (See How to back up a PC.) If you're running Windows 7 Beta on the PC you'll use for test, you can use Windows Easy Transfer to create a backup on an external drive. To find and launch Windows Easy Transfer, just type "easy" in the Start search box.

Recovery disc: A recovery disc restores your computer to its out-of-the-box state. Most computers come with one. If yours didn't, contact your PC maker.

Antivirus program: Make sure your antivirus program is up-to-date, run it, then disable it before installing Windows 7 RC. When you finish the installation, remember to re-enable the antivirus program.

Internet connection: Be sure to connect to the Internet after you finish the installation. Being connected helps make sure you get useful security and hardware updates. We recommend you keep your PC set to automatically check for updates through Windows Update.

Getting ready to install the Release Candidate
What you'll need:
A blank DVD

A PC with a DVD burner

A PC for testing with these system requirements:

1 GHz or faster 32-bit (x86) or 64-bit (x64) processor

1 GB RAM (32-bit) / 2 GB RAM (64-bit)

16 GB available disk space (32-bit) / 20 GB (64-bit)

DirectX 9 graphics processor with WDDM 1.0 or higher driver

Removing the RC
The Windows 7 RC will stop working on June 1, 2010. To continue using your PC, please be prepared to reinstall a prior version of Windows or the final released version of Windows 7 before the expiration date. We recommend doing a custom (clean) installation.

Information about Windows 7 is preliminary and subject to change. Some product features of Windows 7, such as the ability to watch and record live TV or navigation through the use of "touch," may require advanced or additional hardware. The features and functionality you find in the pre-release product may not appear in the final version of Windows 7. If we change the software before it's released, we'll change this information accordingly. We're not making express or implied warranties with this information.
