We know that Microsoft is working on the upcoming operating system Windows 10 and currently a free Technical Preview build is available for download to public so that we all can test its new features and can provide feedback and suggestions to Microsoft.
Since Windows 10 is under development and testing, there are many new experimental features which are put into the OS but are not activated because these features might not be complete and can cause problems to users. On the other hand, some new features are enabled to replace old features but Microsoft also keeps the old features in the OS hidden from users.
Most of the times these new and old features can be enabled or disabled using various Registry tweaks which are applied using our favorite Registry Editor tool.
We have received many emails and comments from our readers who shared various Registry tweaks to enable new hidden secret experimental features in Windows 10 as well as to disable new features and to bring back old features in Windows 10.
Instead of creating separate articles for all of them, we decided to put them together in this exclusive topic for your reading convenience. Special thanks to our readers Ashfaq, Matthew, Johan and Keshav for sharing these tweaks.
