If you have a Windows 7 or 8 PC on July 29th, you will be able to upgrade to Windows 10 for free. This free license will only be offered for one year, but what happens if you need to reinstall your OS? The good news is that the license Microsoft is providing will allow you to clean install Windows 10 on the same device at any time.

The news comes from Gabe Aul, the head of the Windows Insider program at Microsoft. For those who do not like upgrading their machines and prefer to clean install Windows every time a new version is released, this is good news for you. Gabe said the following on Twitter:

Once you upgrade W10 w/ the free upgrade offer you will able to clean reinstall Windows 10 on same device any time

Microsoft is moving aggressively with Windows 10 by prompting Windows 7 and 8 users on their desktop with a free upgrade offer. The company is targeting to have one billion installs of the OS in the next 2-3 years, which means that they have to get users to upgrade quickly if they are going to meet this goal.

The flexibility of the upgrade license will likely put to rest concern that some users were having as they were expecting to have to install Windows 7/8 and then upgrade with the free key that Microsoft is providing if they needed to wipe their machine.
