I am using windows 10 and recently I changed the PC name from its default from the system settings. After this, my desktop wallpaper gets dotted everytime after few seconds when i switch on my PC. Another problem now is that after I changed my PC name, every time when I restart/switchOn my PC, the recently setted brightness changes and the power saver mode always become disabled. Im totally disturbed by all these..Can you please suggest any remedy for this.? Can I set the PC name to its default..? hope you will reply asap...
