Windows 7: How do I undo Homegroup to start a new?

Two computers linked by ethernet cable. Both OSs Windows 7 HP 64-bit. Want to do network sharing. As I followed directions I found that I already appeared to have setup networks. My desktop was Network 5 and the laptop was Network. I was able to find each ones password, but nowheres was I able to find a screen that asked me to "Join Now" (the button, that is). So, I'd like to start over (if I need to), and would like to know how to undo my netork status and start over. BTW, if the two computers were together on a network, how does one get to see the shared files? Just go into Iexplorer??? I'm so new at this.

Hello Flycaster,

You should be able to leave the HomeGroup to be able to start over, then create a Homegroup and join the other computer to it.

Hope this helps,
Shawn

Hate to say this, Shawn, but I've been going around the block with this and keep coming to the same end. Let me explain:

1. I get out of homegroups in both computers as directed in tutorial.
2. On both computers I get as far as writing down the new passwords for each computer.
3. However, I can't find where to enter the passwords. I'm assuming that the desktop's pw goes somewheres into the laptop, and the laptop's pw goes somewheres into the desktop...utter confusion.
4. Some more info. And when I now go to the Network Sharing Center for the desktop I get the following for "View your active networks": Network 5, Access Type - Internet, HomeGroup - Joined, Connections - "some kind of icon and Local Area Connection. And for the laptop the only difference is instead of Network 5, it simply says Network...everything else being the same for both computers.
5. So this is where I'm at: Have passwords for both computers; I'm told that I'be joined even though I know that I didn't see anything that asked me to join; and even if I were properly connected. I'm not sure how one goes about viewing files from the other computer.

Ok Flycaster,

Here are the steps to double check with:
NOTE: Be sure to click on the links below for full details on how to fully do each step.

1. First, make sure that you have removed both computers from the Homegroup.

Homegroup - Leave

2. On computer A, create a Homegroup and write down this Homegroup's password.

Homegroup - Create

3. On computer B, join it to the Homegroup using the password from step 2.

Homegroup - Add Computer or Join

After both computers A & B are joined in the Homegroup. You will be able to access the other computer's library files, that you have selected to share, in Windows Explorer by selecting that computer under Homegroup in the navigation pane.

All goes well (Homegroup established with password on computer A (desktop)) until I get to Step 7 (Homegroup - Add Computer or Join) for computer B (the laptop). At this point there is no button to join, only a button to Create a HomeGroup. Why is this continually happening even though I do have a HomeGroup established on A? See my point 4 above, Network 5 is the network on A. Once again, I have never seen a join button.

Flycaster,

Double check to make sure that you have a "Home network" location (step 4) set for both Computer A & B. Could you post a screenshot of your Network and Sharing Center from both computers? Maybe I may be able to spot something.

Have you also tried creating the Homegroup on Computer B and joining Computer A?

Flycaster, I have the exact problem. NO button to Join now, only to Create a homegroup. This is on my wireless laptop. I have created a homegroup and have the password on the desktop. I have done this in reverse also. Then on desktop I can not get a Join Now button, only to create.

Laptop has joined the homegroup. It was BitDefender Firewall blocking access. I uninstalled BitDefender and downloaded and installed MS Security Essentials.

How did you find out where the problem was? My defenses arer: Spywareblaster, Windows Defender, Norton 360.

Flycaster,

As a test, you can temporarily uninstall Norton 360 completely, then try setting up the Homegroup again to see if that may be the issue.
