While I had nothing to do at work this afternoon, I took it upon myself to figure out how to clean up the system. In truth, I really wanted to find a way to delete history on the PC that I use in case the boss decided to check what it was that I was doing during the day.I certainly did not want him to know I play games and use social media. He has never sacked anyone for it, although he has got a bit angry at other employees when he caught them.
