Tweak Allows Installing Any Win7 Version from One DVD
Now, why do you need a little technical expertise? You need to remove a file from the DVD or from the .ISO image. As Windows Secrets notes, all you have to do is delete the ei.cfg file.
To make things easier for you, the ei.cfg file is in the sources subdirectory (WS didn't indicate its location).
It's simple enough: if you have an .ISO file use an appropriate .ISO imaging program to delete the file from it, then save the image and burn it. If you have the DVD you can use the same program to rip the DVD to an .ISO image, then delete the file, and reburn it.
Once deleted, you'll get a menu of choices, as shown above. You can select any version of Windows 7 to install, and thus try out any version, to see if you really, really want to buy that version.
Also, while the standard trial period is 30 days, just as with Windows Vista, you can extend that through the use of Microsoft's Software License Manager (slmgr), which ships with the OS.
If you install Windows 7 sans activation key, you have 30 days to try the software. Using slmgr, you can "rearm" and restart the clock. If you right-click on the Computer icon, and choose Properties, under Windows Activation, you'll see the number of days left in your trial period.
To restart the clock,
- Click Start, All Programs, Accessories. Right-click Command Prompt and choose Run As Administrator. If necessary, enter your administrator password.
- Type "slmgr -rearm" and press the Enter key.
- Restart Windows 7.
