Whew..what a busy day for me...
First, I performed troubleshooting in some computers with problems in desktop icons' links. It seemed there was registry errors which I suspected was caused by a virus. Good thing there is a post in Microsoft website on how to solve this registry problem and I was able to bring the icons back to their respective links.
Second, I formatted a laptop and re-install OS and some programs which took me couple of hours because of system specifications. The laptop is old which only means slow processing like a snail, haha.
Overall, my time was spent productively and I am very much happy.
