Windows 10 will undoubtedly be the hottest software release of the year – the upcoming OS is said to feature a number of new features and improvements along with the ability to run on a wide range of digital devices including but not limited to computers, smartphones and tablets. Unfortunately there is still some time until we can get the final release version of Windows 10 and until then we will have to do with the early Windows 10 Technical Preview. It is not the whole thing but it is better than nothing.
The good news is that, according to Microsoft, Windows 10 Technical Preview features a roll-back function. This is valid at least for users of Windows Phone who have switched to Windows 10 Technical Preview. In their case if they happen to need a feature that is only available in Windows Phone 8.1, they can easily get back to the older OS version without losing any information.
As to the technical preview version of Windows 10, it will become available later this week or so rumors on the Internet claim. The preview version will be free and will be available to everyone who meets the software’s system requirements but as you know this is not the final Windows 10 version and some features might be missing or not working.
