I always have trouble when I come here getting the right file. I am using Windows 10. Can someone give me the direct link to the tweaking program I need to use to fix Windows 10? I am using an external hard drive. When I tried to save a picture from Facebook to the external hard drive today it said it wasn't responding and eventually timed out. I tried to save a Publisher file today to my external hard drive and it stopped responding and then timed out. One time while trying to save a picture from Facebook I got an I/O error. My external hard drive is fairly new and shouldn't have a problem. When I try to run my anti-virus, it stops at about 80%, both on my C drive and my external hard drive. I don't know if I have a Windows error, a hard drive error, or just what. Any suggestions on top of the correct link would be appreciated. Assume I should run tweaking in case it's a Windows's error????
