Windows 7 and 8.1 PC users should now be seeing a countdown clock when they bring up the Get Windows 10 app. It shows exactly how much time is left to get the free upgrade to the OS before Microsoft's offer expires on July 29.

Windows 10 Countdown

The countdown (via Neowin) appears to be based on the local time of the PC. It's yet another reminder for most consumers who still use Windows 7 and 8.1 PCs that they have less than 10 days to download and install Windows 10 for free. After that, Microsoft will make Windows 10 Home available for $119. There will be at least one exception for this deadline. Microsoft has already revealed that PC users that require assistive technology will get an extension for the free Windows 10 deadline.
