I dual booted Windows 10 with my Windows 8.1 laptop. I had set up Windows 10 as a new PC. But later, due to low space on my hard disk, I removed it. But, in my Internet explorer it still shows tabs from Windows 10, both on my laptop and my Lumia phone. So, now that I don't have 10 installed on my laptop, I want it's data to be removed from cloud. What should I do?
