Annoying Windows 10 Issues

Its been almost 3 months since Windows 10 has launched public. But still there very serious and annoying issues My friends and me are still going through with

1. Right-Click Context menu is extremely slow even on latest build. It still takes 9-12 seconds to open this context menu.
2. Quick Access Menu once crashed, It never starts again. I even contacted Microsoft customer suport, but even they could not fix it.
3. “All Apps” option in start Menu always show ‘New’ even when there are no any new apps added in the system.
4. Wi-Fi automatically restarts.

Under Construction.
