  2. hey guys help me out. my notebook(lenevo y50-70) that was preinstalled with win 10 is flashing a message that my windows copy is not genuine after the december 2017 insider update(build no170633). i have been in the insider programme since 2016 and never faced such an issue. the activation tab is showing error code:0x80080005. plz help

    1. Hellu Satya, If you install the same windows 10 edition (that came preinstalled) windows will automatically get activated using a digital key. Most laptop comes with Single language Windows, so if you install “Professional” or Home edition, you’ll need separate activation key.

      So use the same edition.

      If you want to get involved in Insider preview, test them on a spare computer.

  3. u have no EN- UK language iso, u only got the american version which has conflicts with the native uk keyboard layouts e,c,t

    1. Hey, Danny, Windows 10 Insider Previews uses “Digital Licence” activation meaning you don’t need to input any KEY. Also if you’re updating from an activated Win 10 to Insider Preview you don’t need to do anything it will be activated.

      But I’ve found these keys from reddit as people use them for Insider preview purpose.

      8N67H-M3CY9-QT7C4-2TR7M-TXYCV // 6P99N-YF42M-TPGBG-9VMJP-YKHCF // NKJFK-GPHP7-G8C3J-P6JXR-HQRJR
