If you are having troubles with your Start button and other windows only items, your windows install may be corrupted. Do a system core file check. Search google for windows 10 scannow or whatever it is in this version. It doesn't take long. The other thing to watch out for is your hard drive. Failing drives can cause problems like this even if the drive is new. Had similar problems with a new SSD drive. It worked, but then corrupted files, then worked, then corrupted until I reinstalled over and over again. Finally, sent back to manufacturer and the new drive never has had the problems. It will make you crazy.
