Do not buy this software, it does not work. I purchased the software on line for $ 90 plus dollars because I wanted to be able to monitor and set time limits on my computer. The installation process took most of a day and by the next day my computer started to act up; I could not use the computer as the I could not even log in or shut down the computer w/o great difficulty. I spent about 4 hours on line with the support staff and tech at web watcher and the problem was apparently fixed. By the next morning, the same thing was happening again and no data was recorded apart from a little on the first day. I have submitted 3 tickets asking for a refund and have not gotten a response. I can not even uninstall as the hot key sequence no longer works. I don't know how I am going to get it removed. I am down $90 and will have to pay to repair or replace the computer AND buy new monitoring software. DO NOT BUY THIS, IT IS A RIP OFF AND APPARENTLY THE MONEY BACK GUARANTEE IS JUST HYPE. Waste of money.
