HomeGroup thinking old machine is still hosting. How do i reset ?

Basically the way it works in my home, is i get the latest hardware and then i hand down my mobo, cpu, GPU to my kids each of which have their own gaming pc's and their own Microsoft accounts All running Win10... I'd like to have a homegroup running so that we can share video's among machines.

However when i go into HomeGroup on my new build (Win10 Creators Edition 64bit, clean install) its saying xxxx i7 2600k (machine name) is running the homegroup.

Except the i7 2600k isn't even running on the network anymore under that name. Its now associated with my son's Microsoft account.. I did run services.msc and made sure two services, HomeGroup Listener and HomeGroup Provider, on that machine, are both turned off. This machine would have been upgraded to Win10 from 7 a while back, then used my son's credentials on his own microsoft account.

Where is it pulling that xxxx i7 2600k is running the homegroup ? it must be being broadcast from somewhere, as its an old homegroup that's not been in use for a while now. How do i reset it. I do not have an option to delete or leave any homegroup on any machines.. Actually thinking about it, no homegroups have ever been setup on win10, only Win7, so that was a while back... I want to delete any pre-existing homegroup settings and start from scratch, but i can't seem to find an easy way to do it.

Bottom line, i want to delete anything that is preexisting, then create a new homegroup from my new i7 7700k machine.. but going into homegroup, it just tells me that there's an existing homegroup on my home network.

Any advice ?

Always check tutorials. See Leave Homegroup in Windows 10 Windows 10 Network Sharing Tutorials

Unfortunately the tutorials are for basic leaving and joining with limited troubleshooting.

My path only extends to c:\Windows\ServiceProfiles\LocalService\AppData\Roaming There's no PeerNetworking folder, and yes i have 'show hidden files' enabled.

Again it thinks there's a HomeGroup from an old machine. This machine is a clean install of Win10, so i don't know where its getting this info from ?

thedoc46, Give this a try.

1. Make sure all PC's have left the HomeGroup or are NOT joined to a HomeGroup
2. Turn off all PC's
3. Reboot PC that originally had HomeGroup and now has the phantom HomeGroup
4. After reboot, you should be able to create a new HomeGroup on that PC replacing the phantom HomeGroup. Print or write down new HomeGroup password.
5. Boot other PCs and attempt to join HomeGroup with new password.

Note: Make sure you use the ORIGINAL PC that had the HomeGroup ! (step 3)
Note: Once you have fixed the phantom HomeGroup, you should be able to have all the PC's leave the HomeGroup, then create a new HomeGroup on the PC of your choice.

My bad, I thought the machine in question (i7 2600k) was just upgraded from win 7 to win 10 and that procedure would work

I'm not sure we're reading the same tutorial. The one you linked has a small handful of posts, how to join and leave a homegroup, with one small snippet of troubleshooting. Nothing worthwhile on any real troubleshooting. So i don't really get your point? On the other hand Eagle51 has offered some good advice that i look forward trying this evening. Thank you.

No the tutorials are not basic information. They have all that you need to know about what is stated in them, along with many posts that have gone over this exact same subject. Anything that is found that may be updated, will get put into those tutorials. They are there for a reason and that reason is first stop in helping those needing to fix something, instead of asking the same question that has been gone over and the answer is always to go through the tutorial for your problem first.

Also if it is Windows 7, there is the sister site sevenforums.com, which has the same tutorial.
