How to: Fix Missing System Tray Icons at Windows XP Startup
The above reference allowed me to fix an irritating problem with icons not always appearing in the system tray even though the tasks they represented were actually running.
I applied the recommended fix in Control Panel>Administrative Tools>Services and finally locked the toolbar.
After several days of use the system tray icons always appear correctly.
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
