O.K I'm confused . In all other releases of Win there were two basic forms . The 'full' version and the 'upgrade'. There would appear to be only upgrade versions of Win8 . Am I right in believing that when I build a new system it will involve reloading Win 7 first and then loading win 8. I'd much rather do the job once with a full version of win 8.
It seems there will be "Windows 8" and "Windows 8 PRO" with both these being 'upgradeable' to from what is apparantly an "in place" upgrade within Windows 7 (I recall it says that to go to Windows 8 PRO, this needs to be from Window 7 PRO or Wndows 7 Ultimate).
As far as my current perception goes, it may be that only the 'upgrade' packages are being advertised at the moment, preceding the availabilty of more pricing detail of the full instalation packages, so I would suggest probably we will be hearing more about the full version packages soon.
The £50 version is an upgrade version for your windows XP, vista or 7 computer. Disregard the £190 version. Both versions should be the same price but for some reason amazon charges a ridiculous price for the European version without windows media player.
Wikipedia has a good page outlining the licensing for each version of Windows 7, it's surprisingly convoluted.
The main 3 license options that were available to the home user for Windows 7 were:
OEM - to be installed on a new machine, the license is non transferable Upgrade - to upgrade an existing Windows installation/license Full - to install from scratch, the license is transferable to new machines
For Windows 8, it appears that Microsoft are only offering Upgrade and OEM options.
If you were to build a new system you could use the OEM version. It will allow you to install from fresh, but the license will tie it to your hardware and you will not be able to legally transfer it to a another machine in future. OEM is more expensive than the Upgrade version, however you don't need an existing Windows installation/license to upgrade from.
Windows RT- Tablet version made for ARM processors. Will only run preinstalled on certain tablets. Not backwards compatible with existing Windows programs or hardware. Windows 8- Raw version of the OS. Only available preinstalled on certain systems. Windows 8 Pro- The same but with increased networking features. Available on Oct 26 for £50 boxed or £25 download. Can only be used to upgrade from Windows XP/Vista/7. Windows 8 Pro N- The same as Windows 8 Pro but without a media player due to some legal requirement. £190 via Amazon. Windows 8 Pro Standard Edition to Windows 8 Pro- Upgrades Windows 8 (preinstalled version) to Windows 8 Pro.
So, at this time you can only upgrade from post 2000 versions of Windows to Windows 8 and to preorder, it will cost you £50 or if you buy a download on the day, £25. Hope this clears up any confusion.
Currently I have Win 7 Pro 32 bit which I installed out of choice because I only had 4 GB Ram. Now I want to move to Windows 8 Pro and upgrade to 8 GB RAM. Question Will Windows 8 Pro allow upgrade to 64 bit or do I first have to reinstall fresh Win 7 Pro 64 bit before Windows 8 Pro upgrade?
My understanding is you can do this. You'll have to buy the boxed version from Amazon (or another retailer) and use the supplied 64 bit disc on the install. You cannot do this via Microsoft store as I did. I upgraded Win XP Pro to Win 8 Pro but am stuck with 32bit and the associated RAM limitation. Also the cheap "Upgrade" offer expires on 31/1/13
Stu thanks for that clarification. I also tried out the Microsoft Download and found that it checked the suitability of my PC for Win 8 before offering me the download so I suspected that it would only download the 32 bit version to upgrade the existing 32 bit Win 7. It seems I either quickly install Win 7 as 64 bit and upgrade to Win 8 before before Feb 1st or buy the more expensive Disc package with both 32 and 64 bit DVD's.
That's it. Sorry I wasn't really clear. Upgrades via Windows Store will be on an equivalent basis to the already installed OS. 32bit for 32bit, 64bit for 64 bit but you can get round this buy buying packaged version and install the 64bit version over a 32 bit install or using the method you described.
