I've got a tablet that was used for aviation chart info. I couldn't figure out why I couldn't get updates for windows until I noticed that when I turn the tablet on the clock starts at 01/01/2009. This seems to be causing all kinds of problems. I mention here that I am somewhat computer illiterate so be easy with me if anyone has a solution. I've reset the clock using the internet but when I turn the tablet off and then back on a couple of days later the clock has returned to 01/01/2009. I've even put in all the updates that are available while the correct time is showing but the time problem remains with the next startup. Any ideas?
