So do the following:
Open Network & Sharing Centre
Change Advanced Sharing Settings
Depending on what drop down menu is open for you or what network you selected when you connected the computers via a switch, hub, router or whatever.
Make sure Network Discovery is turned on.
Turn off password protected sharing.
Now do the following.
Share the hard drive or folder using advanced sharing. When you do this limit their permissions. When you go to the Security tab to set up local permissions just add everyone and give them full permission.
This should allow the user from the other computer to access the shared hard drive (now seen as a folder) over the network.
You should be able to Read/Write as this is what you've set in Advanced Sharing.
To make things easy - access your computer on the network, right click on the shared hard drive and create a mapped network drive for easy access via My Computer.
Except that is not what Freelancer852 is asking for as he has already figured that part out. This would allow everyone to have read/write access as long as they are on the same network. OP is trying to give everyone read only access and one specific account to have full control. Limiting file share permissions requires user accounts to an extent but there are ways around it.
OP I'm not sure what you mean by an open home network. There are several ways to do this dependent on your user account setup but a few questions first.
1.) Do all the PCs have specific user accounts with passwords or do you bypass the sign in and go directly to desktop with a generic user account for everyone? Do you have different user accounts but none of them have passwords?
2.) Do you want the user account with full control to access the share from any computer or only allow that user full access from a specific PC?
3.) Have you changed the workgroup settings in any way? Or joined the PCs to a workgroup?

There are other way aside from the ones in that guide.
