Updating windows without a cd
But beginning with Windows XP, PC makers were able to dramatically change the Windows install disc, so much so that, in some cases, those discs weren't even identifiable as valid install media to Windows Setup. In Windows Vista, Microsoft supported in-place upgrades from Windows XP, but if you wanted to use an Upgrade version of the Windows Vista Setup disc to do a clean install, you had to perform a weird double install trick.(I documented this process in How to Clean Install Windows Vista with Upgrade Media.) When it comes to performing a clean install of Windows 7 using Upgrade media, there's no simple answer.We can somewhat understand Microsoft's point of view when they made the product key mandatory for a Windows 8.1 installation. With the Windows 7 30-day trial, one could install Windows and have them for free.Then, once every new moon, they could format and reinstall Windows, and no one would be the wiser.When we download Windows 7 ISOs, we can install Windows without a product key.The installation will go through, and we will get a 30-day trial of the operating system.
However, you can always install VLC to get DVD playback or use one of the more fully featured Windows Media Center alternatives.
The classic method of performing a clean install is still our go-to option with Windows 10.
You just need to download and create installation media, either on a DVD or a flash drive, and install it from there.
With the official Windows 8.1 ISOs, though, we can't skip entering the product key during the installation.
Let's see how to bypass this restriction and install Windows 8.1 without a product key.
