Activation Error code: 0x800705B4 on Windows Technical Preview build 9879

Hi dai49.,

Thanks for your quick response.;  

 But I disagree to your reply,"i seem to recall reading,that the preview does not require activation ".

Its appear that you didn't care the given screen shot also. by the way forget it; Solution that I have

applied is very simple but require some intelligence................. 

Thank you once again.

Here are the installation instructions:

• Plan ahead. Back up your files and settings before installing this preview. 
• While Windows 10 Technical Preview for Enterprise is only available in English, Chinese, and Brazilian Portuguese, the English version can be installed in all markets where Windows is available. 
• Upon installation, Windows will prompt you to activate. A product key is not required for this software. For recovery scenarios, the following key may be used: PBHCJ-Q2NYD-2PX34-T2TD6-233PK
• In order to use Windows 10 Technical Preview for Enterprise, you must sign in to your PC with a Microsoft account. The option to create a local account will be made available at the time of the final release.

Hi dai49.,

Thanks for your quick response.;  

The installation instructions which you have had from"http://www.winbeta.org/news/download-windows-10-technical-preview-enterprise-build-9879-iso" is differs from my experience on this installation and activation process of my own.

1. Upon installation no prompt was made from Windows for activation but only the error (shown in screen-shot that I had attached).

2. Regarding the,"In order to use Windows 10 Technical Preview for Enterprise, you must sign in to your PC with a Microsoft account."  I have installed Windows 10 Technical Preview for Enterprise, without a Microsoft account (but only create a local account). Here I also beg to differ with the Instructions that you refer.

I thin everything is clear to you . 

Thank you very much.

Enjoy your computing with Microsoft Windows.
