What if I already have beta and want to upgrade to RC ? It’s not natively supported so you’ll have to do a small workaround to get it to work..

These instructions will be brief. Since everyone reading is a well-versed and experienced beta tester you know ALWAYS BACK UP YOUR MACHINE before running any OS installation and NEVER TEST AN OS ON YOUR ONLY COPY OF ANY DATA. Testing
a pre-release product means just that—it is testing and it is
pre-release. Even though this is a Release Candidate, we are still
testing the product. We have very high confidence but even if an error
happens once in 1,000,000 we want to make sure everyone is taking the
precautions normal for a pre-release product.

It will always be tempting to get the build with the “mod” already done
but you really never know what else has been done to the build. There’s
a thrill in getting the latest, we know, but that also comes with risks
that can’t even be quantified. For the RC we will work to release a
hash or some other way to validate the build, but the best way is to
always download directly from Microsoft.

Here’s what you can do to bypass the check for pre-release upgrade IF YOU REALLY REALLY NEED TO:

  1. Download the ISO as you did previously and burn the ISO to a DVD.
  2. Copy the whole image 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 pre-release build).
  3. Browse to the sources directory.
  4. Open the file cversion.ini in a text editor like Notepad.
  5. Modify the MinClient build number to a value lower than the down-level build. For example, change 7100 to 7000 (pictured below).
  6. Save the file in place with the same name.
  7. Run setup like you would normally from this modified copy of the image and the version check will be bypassed.


These same steps will be required as we transition from the RC milestone to the RTM milestone.
