Issues with latest win 10 auto updates to fix critical bugs on 13/2/16

[Irene Su]

My issues:
1) no sound (check mute is off!)
2) windows & search icons on menu bar were not functioning, including the window key.
3) Had to press 'alt+ctrl+del' keys for options to shutdown - which went to sleep mode!

Solution:
Restored to previous update as recommended in:
http://windows.microsoft.com/en-us/windows-10/windows-10-recovery-options

Restore from a system restore point [Read the instruction carefully.]
=> Once done, a message showed that it was not completely restored, but it SOLVED the above issues

Note:
Press windows + S keys. Clear and type 'system restore' to change the settings as instructed.

Subsequent auto-updates created the same issues as above.
Intermittent Wifi connection problem due to "network adapter is unavailable" after running "Troubleshoot problem".
It solved itself at the end of run.
