Exactly what the titles says. I started to notice a change with the clock every now and then. I finally concluded that the clock does not change during sleep, restart, or shutdown. My computer goes to sleep often, and when it wakes up from sleep, the time is the same as when it was prior to sleeping, not synchronizing to the correct time after waking up. I've done some research and I fell onto the official Windows thread where they explained the use of third-party-utility will cause this problem. The big problem here is that I don't have the single clue which ones. I tried uninstalling some, not sure if I left any utilities out. I'm stumped. The utilities I've used are the general ones for visual styles and themes. So, here I am. Any ideas? I'm running Windows 8.1.
