Do both PC's have a professional version of windows installed? Such as windows 7 professional?
Do they have local group policy? If so continue:
Why not use a homegroup to share things? or do you specifically want to lock the machines both down with group policy? Remember that applying group policy will apply to all user account on the machine by default.
1.) Follow this tutorial so you do not block yourself after applying the settings:

Set up the local group policy settings the way you like. More information and what each function does can be found on the simple explain setting or on the web.
2.) GPO settings can be copied like this:
Open %systemroot%\system32\grouppolicy\
Within this folder, there are two folders – “machine” and “user”. Copy these to folders to the %systemroot%\system32\grouppolicy – folder on the target machine. All it needs now is a reboot or a “gpupdate /force”.
For security settings:
1.) Open MMC (local group policy) and add the Snapin “Security Templates”.
2.) Create your own customized template and save it as an “*inf” file.
3.) Copy the file to the target machine and import it via command line tool “secedit”:
secedit /configure /db %temp%\temp.sdb /cfg <'yourGP'>.inf
3.) Remote registry is disabled by default under windows 7 for security reasons. If you would still like to enable it, follow these directions:
To enable it on the targeted pc, click

rb: then type "services" without quotes and find the remote registry service. Double click it and change the startup type to automatic. Click start then ok and reboot the PC.
