Upgrading Windows 7 from BETA to RC1

Having read several times now that you can’t upgrade Windows 7 from BETA to RC1, I decided it would be a good idea to post the “how-to” instructions. Obviously many people are confused here.

To upgrade from beta you need to:

  1. Extract the .iso contents to a storage location you wish to run the upgrade from (a bootable flash drive or a directory on any partition on the machine running the old build).
  2. Browse to the sources directory.
  3. Open the file cversion.ini in a text editor like Notepad.
  4. Modify the MinClient build number to a value lower than the down-level build. For example, change 7100 to 7000.
  5. Save the file in place with the same name.
  6. Run setup.exe like you would normally and the version check will be bypassed.

Running Windows 7 Nativity on a Macbook Pro

Windows 7Ever since Windows 7 Beta was released a few months ago, I’ve been hearing great things. So, I decided to try installing it through VMware Fusion and see what all the huff was about. Much to my surprise, it really looks like Microsoft got this one right.

Me, like most others, had decided against moving to Windows Vista because of speed and usability issues. With Windows 7, however, Microsoft it seems has finally finished what it started.

After the collapse of Windows Vista I was snared by the sexiness and speed of the Apple Macbook Pro. Having had some experience with Apple machines back in the mid-90’s I decided to go for it. For a while, I ran bootcamp so that I could use Windows XP and Leopard at the same time, which eventually turned into just Leopard. But Microsoft’s latest release, and the invariable need to run Windows applications, have corralled me back into the world of Windows.

Deciding it was time to run Windows nativity again, I started looking into Bootcamp. Reading several sites, I became aware that Windows 7 was going to be slowed down a little by the bios emulation required to run it. Relentlessly venting this fact my colleagues, and doing some digging, we found that Microsoft had quietly slipped in support for Apple bios replacement, EFI.

Hallelujah! Windows 7 can run native on a Macbook Pro!

So, if you’re like me and want the most performance out of your high end Apple machine and need to run Windows. Go ahead and throw a Windows 7 disk in and get started. Just like with any Windows install, you can delete the drive partitions, even the OSX partition, and format them as NTFS.

Several days of running this configuration have revealed EXCELLENT results. My Macbook Pro has an experience score of 5.0! Much higher than those running Windows 7 via Bootcamp.

Good luck! Please send me any feedback you have with the process as well.
