The download ISO files for Windows 10 build 10147 from the Microsoft’s partners channel recently leaked onto the web unveiling a number of changes and improvements over the last official build. The new unofficial preview shows purely tweaks around the user interface and performance improvements. In addition, the company finally renames its web browser to “Microsoft Edge” and we can see many other small changes.

As always, this is not an official build, as such it’s not recommended to download the ISO files and install the operating system on your main computer, as it’s not supported by Microsoft. However, if you’re still curious to see all the new changes in Windows 10 build 10147, you can watch the new video tour I have published on YouTube highlighting all the improvements and changes:

Even though, Microsoft has said to no to expect any more big changes and surprises on the preview builds of Windows 10, as the operating system is almost complete, build 10147 includes a number of good changes that can be considered a very significant preview. This particular version of the operating system is more stable, snappier, and overall the performance is great.

Microsoft plans to release Windows 10 on July 29th, users are already being offered to reserve their copy for free on Windows 7 and Windows 8 devices, and we expect Windows 10 to roll out in 111 languages and 190 countries.
