I had a program called StartIsBack installed on my computer, and after deciding that it was not needed, I removed it. Recently, when I log in, I can see that there are updates available to Windows. However, when I try to enter Windows Update in Control Panel it either does not load and crashes, or loads in, shows me that there are 5 important, 4 unimportant updates, and (control panel)freezes when I hit install. Things I've tried I've ran CCleaner, and Malwarebytes, and retried to no avail. Tried booting into safe mode, and then updating it I've tried using a system restore, and got an error code. I can't remember what it was, but when I googled it, I saw that it was related to Windows update somehow, maybe a missing file. I've tried refreshing Windows; it freezes when I do it from within the system, and I got an error message saying the drive was locked when I tried via my OEM disk at startup. Any ideas?
