How to modify group policy using powershell?

Hi,

I am trying to configure hash publication for branchcache and below are the steps.

Click Start, click Run, type mmc, and then press ENTER. The Microsoft Management Console (MMC) opens.

2.    In the MMC, on the File menu, click Add/Remove Snap-in. TheAdd or Remove Snap-ins dialog box opens.

3.    In Add or Remove Snap-ins, in Available snap-ins, double-clickGroup Policy Object Editor. The Group Policy Wizard opens with the Local Computer object selected. ClickFinish, and then click OK.

4.    In the Local Group Policy Editor MMC, expand the following path:Computer Configuration, Administrative Templates, Network, Lanman Server. Click Lanman Server.

5.    In the details pane, double-click Hash Publication for BranchCache. TheHash Publication for BranchCache dialog box opens.

6.    In the Hash Publication for BranchCache dialog box, clickEnabled.

7.    In Options, click Allow hash publication for all shared folder, and then clickAllow hash publication for all shared folder.

8. Click OK.

I think, group policy cmdlet can do this. But I am unabale to find the GUID and Key for the same. Can anyone help in doing above steps using powershell?

Also, please guide me on using powershell for managing/modifying the group policies.
