You have to make Everyone, not Anyone, appear in the Security Tab, viz. In Computer, go to the drive or folder, right-click it > Properties > Security Tab > Edit > Add then type ‘Everyone’ (not the quotes) and below it select your preferences, e.g. Read or Full Control. Now Apply, OK etc. to finish.
If it’s still not sharing, make sure in Control Panel > Network and Sharing Center you have Password Protected Sharing ticked as ‘off’. Also, make sure Network Discovery and File Sharing are both ‘on’.
