Microsoft will start upgrading Windows 7 and Windows 8 machines to Windows 10

In less than 24 hours, Microsoft will start upgrading Windows 7 and Windows 8 machines to Windows 10. The software giant is preparing for this big release, at 12AM ET on July 29th (9PM PST on July 28th), by pre-loading the final version of Windows 10 on PCs eligible for the upgrade. A number of Windows 7 and Windows 8 users who have registered for the upgrade have started noticing that the full installer files for Windows 10 have been downloaded to C:\$windows.~BT as Microsoft gets ready for release.

In my case Windows 10 have been downloaded to C:\$windows.~WS ... Now I'm creating Windows 10 ISO 32 and 64 bit via media creation tool... Notice the Product Key config is Xrml (Digital License)..

Microsoft will unlock and activate the Windows 10 install at midnight tonight, allowing some Windows 7 and Windows 8 users to upgrade. Not everyone will get access to the Windows 10 upgrade initially, though. Microsoft is rolling the upgrade out gradually to compatible systems, and the company is creating a queue to distribute the update in waves.

Windows 10 testers (like me) have already been testing the final bits and they will be the first to receive a Day One patch that Microsoft is developing. The software maker has also been rolling out daily hotfixes to existing testers.
