I keep getting an error that says the user profile service service failed the logon, user profile cannot be loaded. I can't at all log into windows at all. So I googled it and found a solution. I went into safemode but when I search it regedit doesn't come up? Is there someway to fix this? Or if not is there an easy way to simply wipe it all back to basics without losing the copy of windows on the harddrive?
