Don't uninstall Steam using CCleaner

I was doing some housekeeping for my primary HDD recently when suddenly my Steam client got corrupted and unable to launch games. So I did the same as with many problematic applications that I have; uninstall and reinstall it. As usual, I uninstalled it with CCleaner, as how I uninstalled everything on my PC. Took longer than usual but it uninstalled. Which come to my surprise when I realize that all of the games in my Steam folder was also wiped out. Nooooooooooooooo! Well, too late to regret. Checked on a few forum on the net and they said there were an option of what to uninstall when removing Steam but it didn't prompt when I uninstall it using CCleaner. So there you have it, wiped out around 25GB of games that now needs to be redownloaded. Luckily all of the save game files are stored on different parts of the PC and it is safe and also lucky it was on Steam so it can never actually be lost since I still own the game on Steam. Lost all of my Non-Steam games shortcut though. These are the games that I lost and need to be redownloaded.
