I have been running windows 10 technical preview on my Dell laptop just fine for quite a while now, but when this morning many things went wrong.
I was restarting by pc as i was having some problems with the start menu not displaying by pinned tiles correctly.
I restarted my pc and the start menu refused to open and the taskbar was dead (see-attached screen shot). The notifications area was also dead; with only the clock popping up if, I pressed an icon that was not there.
Because of this, I have not been able to use explorer.exe, so I have been stuck to using CMD and 7-zip for file management, and multitasking without a taskbar has been a horrible mess.
I installed a copy of windows 10 on a virtual machine, and the same problem occurred...?
I have tried replacing explorer.exe with the explorer.exe from that VM, but with no luck, I reverted to the original one.
I have tried using this guide:
https://www.techmesto.com/fix-start-menu-broken-windows-10-technical-preview/
However, it did not provide any solution that worked for me.
I have also noticed that explorer.exe is hogging about 50% of my CPU.
General specs of the laptop:
Dell Vostro 1510
Intel Core 2 Duo T5670
4GB DDR2 RAM
320 WD Scorpio black HDD
Integrated Intel GMA X3100
Any help would be highly appreciated, as this laptop is my main workhorse at school.
