    For those needing a product key for use with the new Windows 8 Release Preview (in case it isn’t obvious) this is what Microsoft says to use:


    For those who wish to verify they downloaded a good English language copy, the hashes for the .iso files are as follows too:

    32-Bit (SHA-1): 8BED436F0959E7120A44BF7C29FF0AA962BDEFC9
    32-Bit (MD5): 7285DA50A07E33BC3B5A20E48AFAF375
    32-Bit (CRC32): 70B0ACEA

    64-Bit (SHA-1): D76AD96773615E8C504F63564AF749469CFCCD57
    64-Bit (MD5): 5901DB43F3B3FA155D65F523F76D5D88
    64-Bit (CRC32): B3FB2EBC

    You may notice that Microsoft publishes these hashes with a “0x” at the beginning and only provides it in the SHA-1 calculation. Just disregard the “0x” and the hashes should be exactly the same. I provided the other calculations (MD5 & CRC32) as reported to me using my own checksum calculator that also provides the correct SHA-1 calculation after downloading.

    Speaking of which, if you want a good checksum calculation tool (for Windows) I suggest trying the Advanced CheckSum Verifier (ACSV) from Irnis:

    @beammeupscotty: Yes you can. I accidentally did it and it worked, then I reformatted the HDD and reinstalled only the W8RP. [:

    @Mark: I didn’t have a single problem since I installed it. [W8RP6Bit]

    Here are some pictures otherwise, for those who didn’t have time to test it yet:

    If you want to try the Windows 8 Release Preview, I noticed that Microsoft says you must minimally have the following hardware (which most virtual environments like Virtual Box and VMWare usually have no problems with, and assuming the host/real PC has the resources to offer too):

    * Processor: 1 gigahertz (GHz) or faster

    * RAM: 1 gigabyte (GB) (32-bit) or 2 GB (64-bit)

    * Hard disk space: 16 GB (32-bit) or 20 GB (64-bit)

    * Graphics card: Microsoft DirectX 9 graphics device with WDDM driver

    If your system doesn’t meet these bare requirements (or you don’t have them available it in a virtual environment) then don’t waste your time.

    i would like to install windows 8 previw but im useing windows 7 media center if i install windows 8 will i beable to install the windows 7 meadia center on it?

  9. wlb

    I just installed the RP in VMware Workstation 8 from within a running instance of the CP. Nothing can be saved (apps, settings, etc.). You can mount the image in a virtual drive and the installation goes very smoothly. You are left with a fresh clean instance of Windows 8.

  10. wlb

    Also, VMware Tools installs in this Release Preview. I also installed the new Win8 Server build 8400, but the installation would not accept VMware Tools

    Does it work wid centrino duo processor 1.66gh please

  12. George

    option to turn off metro?

  13. Jared

    Metro-izing the desktop made it FUGLY.

    @Henman2 It does, the minimum Processor requirement is at least 1GH.

  14. becky

    does windows 8 cost or is it free and how much

  15. TheRacerMaster

    @becky This is the Release Preview of Windows 8, so anyone can download it for free. It will expire when the final version is released to the public. You’ll need to buy a license at that time.

  16. RichardP

    These (4 items below) are not the only requirements for running WIN8-RP, which are different than WIN8-CP, which does not require PAE enabled.

    * Processor: 1 gigahertz (GHz) or faster
    * RAM: 1 gigabyte (GB) (32-bit) or 2 GB (64-bit)
    * Hard disk space: 16 GB (32-bit) or 20 GB (64-bit)
    * Graphics card: Microsoft DirectX 9 graphics device with WDDM driver

    Your BIOS must be able to enable PAE (Physical Address Ext) and many classic vendors do not allow access to this in there version of BIOS, including many Intel i-series processors. One can try an upgraded BIOS, if available for their hardware, but it is not enabled, WIN8-RP will halt and not install !

    Is there any method by which I can upgrade from Developer’s Preview. I need this to keep the dual boot MBR with Ubuntu and the chainloader for Windows 7 and 8.

    At present Grub offers Windows 7 and Ubuntu. When I select Windows, there is another choice menu for Windows 7 and 8 Dev Preview.

    I have a HP Pavilion dv6 Notebook Computer and have been unable to install the Windows 8 Preview at all. The problem that I have is that according to all the help forums, etc, that are out there show the Hard Drive as being a Basic Drive, whereas my Hard Drive in my system is a Dynamic Disk. Everything I read about changing over from a Dynamic Hard Drive to a Basic Drive state that if you do that this will cause you to loose all of your data, etc. and I cannot under any circumstances, afford to loose any of my data, etc. Why is this the case. I have Computer Certifications including A+ Certification and have been able to build systems from scratch, troubleshoot systems, and even re-program them if necessary. I have been a Beta Tester of previous Microsoft Products and have enjoyed being a tester, and when I saw that we could download and install the Windows 8 Preview version, I was thrilled to pieces, but rather disappointed because nowhere did it state that your Hard Drive had to have the basic format instead of the dynamic format. As a retired CPA and member of the Utah State Bar, a very important piece to the puzzle was inadvertently left out of the Download and Installation Instructions. How can I download and install this Windows 8 Preview without damaging my system or else risk loosing a lot of extremely important financial, legal, and miscellaneous data files by changing my hard drive over to a Basic Drive. By the way I am using Windows 7 Ultimate SP1 on my system and I have plenty of room to install this new Version of Windows. I can create the Virtual Disk Drive with no problem, but the installation program will not allow me install the O/S. I have tried both ways of installing the software and get the same results.

    If you go for Windows8-ReleasePreview-64bit-English.iso use TK8TP-9JN6P-7X7WW-RFFTV-B7QPF and remember to point the DVD to the ISO if you use VirtualBox.

    I’m skipping Windows 8 waiting until the release of Windows 9, the dual 64-bit platform.

    Some really bad advice on this thread… throwing caution to the wind and downloading an OS that is not yet ready for prime time just to be the first geek on the block that can brag about the new look. If you are getting baited to download an OS on a system that has confidential files and you did not back up that info on an external drive, or you just got on this website and were bored and figured “what the hey” I have nothing better to do than psych myself out and download an untested OS, I have no pity for you.

    I signed up for the Windows 8 upgrade from Windows XP/VISTA/7 but I want to make sure that my personal data is secure first. Good grief. Some of you may have the IT cert (I do – MCSE/A+) but there are other fine people who get on here thinking that an OS upgrade is just push and shove and voila!, a new OS w/o problems. Where’s the caveat???

    Important: If you decide to go back to your previous operating system, you’ll need to reinstall it from the recovery or installation media that came with your PC, which is typically DVD media. If you don’t have recovery media, you might be able to create it from a recovery partition on your PC using software provided by your PC manufacturer. Check the support section of your PC manufacturer’s website for more information. After you install Windows 8, you won’t be able to use the recovery partition on your PC to go back to your previous version of Windows.
