I never had a problem with logging into Windows 10 rather quickly...up until just a few days ago...since the 10525 version came out. Now it takes about 5 minutes of me starting at a completely black screen to get logged into Windows 10 after entering my password. And Windows 10 is installed on a 250GB Samsung SSD. LOL. My Windows 7 machine blows my Windows 10 machine all to hell and back now. Glad I got 2 computers still. ** EDIT **: Come to think of it, this may actually be my fault. I was setting up permissions on my hard disk so that I could share some videos with people on my home network...it turns out Microsoft had some crazy default settings that "literally" let people browse the administrators "My Documents" folder when they are logged in remotely. Unbelievable. So I had to restrict that ability and in doing so think I have somehow locked myself out of a folder or file that Windows 10 tries to access during login. It takes about 5 minutes before giving up on that and showing the desktop. Oh, also, I can no longer access the "crappy" new rainbow colored start menu. It sucks yes but I still want to be able to use Windows 10 like it was intended. Now I gotta figure out how to get all this back to normal.
