Thread: Windows 7 upgrade

To introduce the retail edition of Windows 7, Microsoft has for students with a particular upgrade give at hand owners can buy a edition of Windows XP or Windows Vista to upgrade to a retail edition of Windows 7 Home Premium or Professional, present in 32 - or 64-bit edition. The fact that this is a download edition, should not interfere with most users, especially since the order also has a DVD can be added.


When the download is - to the chagrin of many unsuspicious buyers - but not an ISO image that can be burned to DVD. Rather, the client will obtain a download manager that will download three document in total, one of them an EXE. This unzipped the three documents into a directory named expandedSetup, basically entire the documents in a Windows 7 disc and contains the running system is to be started upgrade routine. Problems can now give.


If you want to switch from an existing 32-bit Windows to a 64-bit version: the upgrade process will not start. Even a fresh install without an installed operating system is the first upgrade package is not possible. But with the right software and an appropriate instruction, on the side of the Windows Seven Forums is described in English, can be created from the downloaded files in a few minutes a bootable DVD.




After purchasing the upgrade version you get the link to a download manager. In the case of Windows 7 Professional 64-bit version is called the DLMWin7Pro64DE.exe, differs from other versions of the name accordingly. If you run the file, the three files are setup1.box, downloadedsetup2.box and Win7-P-Retail-de-de-x64.exe with the name of the last file in turn depends on the version purchased.


The next step leads you from the just downloaded EXE file, and then the installation files are unpacked in the folder expandedSetup. Adjust operating system upgrade and together will now automatically start the upgrade routine that we stop, however, eventually we want to create a bootable medium. An appropriate error message appears at the end of extraction can be safely ignored, the files are still all there.


Now we need the Microsoft-supplied command-line utility Oscdimg, officially unfortunately only in the Windows Automated Installation Kit is (AIK) include, may be, however, after passing the WGA check downloaded for free as a DVD image. This may for example with the free download area available CDBurnerXP to burn to a disk. Previously, we must have the extension of the DVD image but of. Change img to. Iso, as our program can only deal with the latter. For other burning programs to change the file extension is not given if necessary.
