'Show Desktop' icon gone?

One of my all time favourite things is my quick launch tray at the bottom of my screen. I don't understand people who don't use it. I mean, why waste time having to hunt for programmes you use frequently? Yes, you can use the 'Desktop' toolbar, and save shortcuts on your desktop, but I have SO many there already, that to find the one I'm looking for can be a bit like looking for a needle in a haystack. Instead, I keep the top 10 apps I use in my quick launch toolbar/ tray.

Of those, the most frequently used one is the 'Show Desktop' one. Again, I know visually where my different shortcuts are, so it's quicker for me to find something by looking at my desktop, than looking in a LOOOOONG list of apps using the 'Desktop' toolbar.

Needless to say, I was therefore VERY frustrated to find that one of the teachers using my room accidentally deleted it. Yes, if you right click on the bottom toolbar you have an option to 'show desktop', but that's a WHOLE EXTRA click, and it's hard to break the habit of a life-time.

Today I eventually decided enough was enough, and Googled a way to fix it. I found a really easy way to do it. YAY! I love Google and I love it when technology works so simply. So, for those of you in a similar boat, who have accidentally deleted it, or have had someone else do it for you, here's the solution:

·         Click Start -> Run and type regsvr32 /n /i:U shell32.dll and enter
