When i woke up the computer this morning, It gave me a warning that my hard drive was full. the back-up files and downloaded files combined to 120 gb!! I had 10 to remove the files getting my space back. I found a update that hadn't downloaded or installed. So i went to download and a screen came up with "needed to troubleshoot windows update". Now it shows another window showing it has found a issue and asked me to have 10 fix it. Under resolving issues it says " Starting Bits Service". Its been at this for a hour. The hard drive light on the front of the tower hasn't blinked for almost all that time. Should I just stop it and try downloading direct from Microsoft?? What is Bits service anyway?? Another thing is the mouse seems to have a hiccup moving around the screen. Keeps freezing for a second then trys to move wherever i was trying to move it too.I was thinking about a restart and going to Microsoft for the download but wondering if that would screw it up more? Any ideas?? Help!
