Buy A Computer with Windows Pre-installed

The easiest way to get Windows 7 is by buying a computer with Windows pre-installed. This is the easiest way because there is no purchasing of serial key includes, no Windows setup includes, no hassles, no bassles. In this case, your system has a Windows version pre-installed so that it can perform nicely. The only drawback is that, if you already have a computer you will have to get another one. And they will offer the Windows 7 Professional, not any other Windows version if you buy a Windows 7 computer.

Can a Windows DVD/CD get me a product key?

If you have an installation media, that does not mean you can get a Windows 7 product key from there for free. The product key is not pasted in a Windows retail card does not matter what version is it. Nonetheless, some users have a Windows disk restored where you can find the Windows 7 Ultimate product key saved in a file. But that can also be used by another user so you cannot re-use it again. And that won’t help you activate your Windows.

Can the same key be used twice in a different machine?

If you have already used a key on a computer, you cannot use it twice on a different computer. Usually, Microsoft does not allow that for users but under a few situations, this might be possible. You might have various copies of Windows installed on multiple computers but one product key can let you activate it on one machine only. But you can install the version on different computers and use it without activating it. Use the trial version for 30 days and when it asks for activating the product after the trial period is over, simply ignore.

These methods will help you activate your Windows 7 without a serial number. For further queries, drop us a comment below.
