Start menu in Windows 10 does not work anymore

Posted by Ed on December 8, 2015

Today I’ve finally received the notification for downloading Windows 10 as an upgrade from Windows 7. I had reserved it earlier a few months ago and was already worried that something was broken because it took so long. The installation was ¬†smooth and went without any problems.

One thing I don’t like in Windows 10 is how the font looks like. The letters are suddenly so thin and it appears as if the antialiasing is too high compared to how they looked in Windows 7. I will have to look into this deeper later.

The next day I encountered something annoying. The start menu would not show up anymore, symbols in the task bar on the bottom right were not being displayed, and in the center of the task bar the icons for the browsers were missing. As a result, I couldn’t reopen a browser window after having minimized it.

Turns out that the culprit was Windows’s hibernating mode. When I shut down¬†my computer I also turn off the power completely with a switch on the power strip. However, the computer needs some power in hibernating mode, otherwise data will get lost and this is probably what lead to the problems mentioned above.

Disabling the hibernating mode shuts down the computer completely and also allows turning the power off completely. To do so press the Windows Key + X and open a command prompt with administrator rights. Enter the command

powercfg -h off

This has resolved all the problems.
