So I have done something really foolish and need help ASAP. I have a tablet with 8.1. Last night I decided to use the "add more features to 8.1" link and so then I had entered a product. My tablet told me it was adding features, restarting etc. However something was wrong. When it restarted it wasn't added with features. I got a windows 8.1 build number at the bottom of the screen, and my pc info told me it was NOT activated. I panicked almost. thank god this was my new tablet and not my mainstream gaming laptop. I tried to refresh the pc and didn't work. The only thing I can think of now is backing up whatever I have and restoring to factory settings. But I need to know if that will really work out or not. If not what other options do I have?
