To get back the “show desktop” icon do the following:
- Make sure “Quick Launch” is enabled
- Right click on the taskbar and then click on “Properties”, and a box will pop up.
- Under the taskbar tab, check the option that says “Show Quick Launch” and then click on “Apply”.
- After you are done with this, click on “Start” and then click on “Run”. A small box will pop up on the right hand corner. If any text is present, delete it and type the command “regsvr32 /n /i:U shell32” in the open box without the quotes. Wait for a couple of seconds and you will see a small window, which says “DllInstall in shell32 succeeded”.Now, you will be able to see the “Show desktop” icon again.
