Windows 7 RC (build 7100) expires March 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."

I didn’t realize I still had the RC Build running on my primary workstation.  I have also been very busy and am *not* keen on spending a day doing an entire system rebuild.

Although Microsoft (and most IT Pros) recommend a clean install with the production code (Build 7600), there is a way around the problem.

If you attempt a standard upgrade by running setup.exe using the latest build, the upgrade fails, and you receive the message below:

The way around this issue is to copy the contents of the DVD (3.01 GB for Ultimate x64) to a folder on your drive. 

Next, edit the source\cversion.ini file using a text editor like Notepad.

Edit so the MinServer and MinClient values match the example below and save the file.

[HostBuild]
MinClient=7000.0
MinServer=7100.0

Run setup.exe, and proceed.  You will need a valid license key for Windows 7 and your system will be upgraded.  You can confirm the new version by typing the command “ver” from the command prompt.

Microsoft Windows [Version 6.1.7600]
