Clear Notification Area History List

After a long run with your Windows, you might find a list of redundant history listed in the "Customize Notification Icons" window. These also includes the software icon the you have already removed from your computer. To clean up this list you need to modify your registry a bit.

The process is simple, you only need to clean the values stored in 2 binary value strings in the Windows registry:
1. Open your registry editor by typing 'regedit' in the Run dialog. (without the quotation marks)
2. Browse to the following location:
HCR(HKEY_Classes_Root)\Local Settings\Software\Microsoft\Windows\CurrentVersion\TrayNotify\

You will see the following 2 binary value strings:
- IconStreams
- PastIconsStream

All you need to do is to clean up all the value stored in these 2 value strings. (Quickest way is to delete and create these 2 "binary string" with the same name.)

3. Open "Task Manager" (Press "Ctrl + Alt + Esc")
4. Click on the "Process" tab.
5. Find "explorer.exe" and right click on it.
6. Select "End Process"
7. Click on "File"
8. Select "New Task (Run...)"
9. Type 'explorer' and press enter to reopen the explorer process.
10. Done, the notification icon history list is cleared.
