After 9 months of public beta testing, Microsoft is set to unlock and activate the Windows 10 install at midnight, allowing some windows 7 * 8 users to upgrade.

Microsoft is rolling the upgrade out gradually to compatible systems, and the company in a blog post says it’s creating a queue to distribute the update in waves.

One can now upgrade to Windows 10 free of charge if one has Windows 7 or Windows 8.1 on one’s existing PC.

While not every single machine will get the upgrade instantly, Microsoft is rolling out the install to millions of devices. All one has to do is register for the upgrade from the taskbar, and Microsoft will send an alert once it’s ready to be installed.
