How to bring back the old resizable Start Menu running Windows 10 build 9926

With the recent arrival of the new Windows 10 January Preview, a number of new features and changes came included. One new change is the Start Menu, which for some has become a pain to use with the new Continuum mode. Luckily, the code for the old-style 9879 Start Menu is still present, meaning it can be re-enabled with one simple registry tweak.

Just follow the steps below:

1. ​Right click on the Start Button and select “Run”
2. Type “regedit”
3. Navigate to HKEY_CURRENT_USER>Software>Microsoft>Windows>CurrentVersion>Explorer>Advance
4. Create a new DWORD (32-bit) value, call it “EnableXamlStartMenu”
5. Restart Explorer​

Thanks for the tip, BAV0
