Tray icon disappears

I've been experiencing since the installation of Windows XP SP2 on multiple machines with the ATITool Tray Icon disappearing upon load at system startup. Sometimes it's there, sometimes it's not. Enabling or Disabling the "Hide Inactive (tray) Icons" WinXP menu option doesn't have any effect. The only way to open ATITool after it has loaded is to go through the start menu to open it again. I have "minimize on close" selected in ATITool. When closing ATITool, you see it make the motions of minimizing to the tray area but no icon is displayed. Any ideas?

 

Icons disappeared and theme changed.

Hi Roland,

Corrupted system files may be one of the possible causes why the icons on your desktop disappeared. To assist you better, kindly answer the following questions:

• Have you made any recent changes prior to this issue?
• Which build and version of Windows 10 are you using?
• Have you tried creating a new user profile and check if the problem is in the current profile or also with the new profile?

Meanwhile, I suggest that you follow the steps shared by Meliton Dec on this
thread.
The given troubleshooting steps will help repair or reset not only missing apps but also lost icon.

Additionally, You can reset the Icon Cache. Kindly follow the steps provided below:

• Open File Explorer and navigate to the following folder:
  
  C:\Users\%username%\AppData\Local\Microsoft\Windows\Explorer
• In the Explorer folder, you will see a lot of files with the
  iconcache name. Delete all of them.

Once you have deleted all the iconcache files, a folder names IconCacheToDelete
will appear. Simply restart your PC and this folder will disappear.

In the event that you are unable to delete some of the files, see the steps below:

• Open elevated Command Prompt. (Win+X > Command Prompt (Admin))
• Type the following command, and then press Enter:
  
  cd /d %userprofile%\AppData\Local\Microsoft\Windows\Explorer attrib –h iconcache_*.db del iconcache_*.db start explorer
