How to Fix “Cookies must be allowed” on Windows 10?

Issue: Hello guys! I’ve upgraded my PC to Windows 10 a long time ago and enjoyed its smooth run, thanks to Microsoft. However, recently I’ve switched to 1607 build and started experiencing cookies issue in OneDrive. After the upgrade, setting up OneDrive ends up with a message saying “Cookies must be allowed.” I’ve checked each web browser on the system and found out that most of them, except Firefox, have cookies enables. I’ve enabled cookies on Firefox as well, but that did not help. Is there any fix for this?
