If rumours are to trust, looks like Microsoft has finished its upcoming operating system. The Windows 10 will be officially announced on July 29, while the first PCs with the pre-installed operating system won't arrive until a few weeks after the release.

The source close to the matter says that the final release build is 10240, which should be sent out to OEM partners. Microsoft is signing off on the build today, and there is a chance we could see the RTM version by the end of the week. If that doesn't happen, we won't have to wait long for the official version.
