How To Legally Reinstall Windows 7 Without Product Key

 

The problem with this traditional procedure is that you need to enter the product key. This becomes a bit more complicated if you have lost your Windows 7 DVD box on which license key is printed or if you have deleted the mail containing your product key for Windows 7.

While there are plenty of applications out there to recover Windows 7 product key, including a free tool to recover Windows 7 product without booting into Windows 7, wouldn’t it be good if it was possible to legally re-install Windows 7 without entering the product key?

 

The beauty of Windows 7 and one of the hidden features of Windows 7 is that this version of Windows can be re-installed on the same PC without having to enter the product key, legally. In other words, if your Windows 7 PC is working and bootable, you can re-install Windows 7 without a product key without the help of third-party tools provided that you have a Windows 7 installation DVD.

Note that you must use Windows 7 installation DVD as a bootable media as a bootable Windows 7 USBdoesn’t help in this method.

Things you need to know before beginning to reinstall Windows 7 using this method

# This guide is helpful for those who have a Windows 7 DVD but not the product key.

# Your Windows 7 PC must be bootable and your PC must have an optical drive (DVD drive).

# Your PC must have at least 16 GB (for 32-bit) and 20 GB (for 64-bit) of free space on your Windows 7 drive (the drive where Windows 7 is currently installed). If there is no sufficient space, you need to free up some space by disabling hibernation, uninstalling programs, emptying Recycle Bin, or running disk clean up utility.

# After performing reinstallation, you’ll need to manually install all applications all over again, meaning you will lose all installed applications during the reinstallation.

For those who’re curious, in this method, Windows installer simply moves all files and folders located currently in the Windows drive to a folder named Windows.old on the same drive. And once reinstallation is done, it even allows you recover those files and folders but not applications from the Windows.old folder.

Step 7: Finally, insert your Windows 7 DVD into the drive before clicking the Restart button.
