Windows 10 is ready and on its way to PC manufacturers so they can start installing it on their operating systems ahead of the 29 July release date.
The Windows 10 RTM (Release To Manufacturers) build 10240, is the final build of the OS. This build is what we all will receive come July 29 when Windows 10 officially releases. Windows 10, being the last version of Windows means that there will never be another release roll out like this unless a substantial update is released, marking this a historic event in OS history.
Current Windows 7 and 8/8.1 users will have one year to upgrade their version of Windows to Windows 10 for free. You can reserve your copy now and let it start installing as soon as Microsoft starts the rollout close to the 29th.
Microsoft have commented on the state of the rollout saying that it might take a while for manufactures world-wide to receive their RTM copies of Windows 10, but with most Windows users running the versions that will receive the free upgrade, I don’t see why this delay would be an issue.
