Windows 7: windows cant remove your computer from the homegroup

I have been trying all day to remove my computer from the home group. The error reads "windows cant remove your computer from the home group" I have spent hours reading blogs and trying what other people have done to fix the same problem but I have not had any luck. I have gone into services and activated the peer networking but still I am not able to disconnect. I am running out of patience can someone please help. I have gone as far as calling HP but they want to charge me $200.00 and I dont have that money right now to spend....

This is all I see for fixing this problem though I'm sure you have seen this before.

The fix for this problem seems to be Deleting the file idstore.sst under C:\windows\serviceProfiles\LocalService\AppData\Roaming\PeerNetworking

And there is a good chance you will need to delete the entire folder, so everything including this entire file On all machines in the network >C:\windows\serviceProfiles\LocalService\AppData\Roaming\PeerNetworking Needs to be deleted. After that you will want to leave the Homegroup on all machines and create a new one.


Start the Task Manager
Click on the service Tab
Find the "HomeGroupProvider"
and then stop the service.


You may need to go back into services and enable Peernetworking again after the fix. Don't forget to restart all machines making the adjustments.

You are right I have done that and when I go and start peer networking and restart its not running. For some reason it wont stay running. I have been looking at other posts something about window firewall do yu thing that might have something to do with it because i am receiving an error on that too. "windows firewall can;t change some of your settings error code 0x80070424. I am very frustrated and want to thank you for replying

It seems that in many cases the entire roaming folder needs to be deleted and you may also need to do the same thing on all network machines.

Here is another thread that shows success by being very tenacious about removing that entire file on all machines.
Cannot leave Homegroup

so i should go and delete the whole roaming folder? just want to verify before I do this lol

As you can see in the link I posted, that seems to be what it takes to fix this problem, not to mention deleting the file from the other Homegroup machines.

deleting from the other computer even though it was able to leave the home group

Yes the file is recreated as soon as you create a new Homegroup.

ok i deleted the roaming file and restarted... then started peer networking and restarted and tried leaving still don't leave I looked in services and peer network doesn't seen to stay running after i restart...

also i looked into home group listener and that wont start there is an error does that have anything to do with this?
