Start & windows Settings are not working

Question

i Recently Updated to windows 10 Technical Preview SL, Evaluation Copy. Build 9926
I can't access Start neither by Windows Start Window Icon nor by  the Key Board Windows Button.
I thought that the problem would be solved by the updates, but the windows updates is no longer in the control panel and the PC SETTINGS is not launching and the window opens only having the Settings enlarged icon.
Thank You,

This is a  direct copy from Insider Hub regarding how to check for Windows Updates when Start Menu is not functioning. Hope it also applies to your issue.....
Start menu
When you boot Windows 10 Technical Preview, the Start menu may not appear. Checking for updates may fix this problem. To check for updates without the Start menu, do the following:
Select the Internet Explorer icon.
Type http://update.microsoft.com into the address bar and select
Enter.
If you are prompted to run a control, click
Yes.
This should bring up the Check for updates window. Install updates.
If no update is available, or the available updates don’t fix the issue, restart the device–this should make the Start menu appear. To reboot without using the Start menu:
Hold down the Windows key and select L to lock the device. Swipe up or select
Enter to open the sign in screen. Select the
Power icon on the log in screen to restart the computer.            
OR
Hold down the Windows key and select R to bring up a command prompt. In the prompt, type
shutdown –r to restart
