So i installed Windows 10 Pro OEM yesterday and everything was going fine, but then cortana kept popping up, and i thought about deleting it. So i used this guide. But after that i couldn't use the search function, so i reset my PC to factory new setting (without cortana), but i still can't use the search option. I have tried this guide (Both methods), but it didn't help me at all. So does anyone know a fix?
