when i try to change the password of my homegroup i get the error: "windows cannot set up a homegroup on this computer". why is this?

I don’t know the answer to the password problem, but you could try leaving, creating and joining: LEAVE/DELETE Go to Control Panel > All Control Panel Items > Homegroup > Leave the Homegroup and click Leave the Homegroup. If all the computers leave the Homegroup, it will no longer exist, so it‘s effectively deleted and can be setup again. CREATE Go to Control Panel > All Control Panel Items > Homegroup > Create a homegroup > Select the folders you want > Next and make a note of the password that will be used by other computers to join the Homegroup. JOIN Go to Control Panel > All Control Panel Items > Homegroup > Join now and type in the password.

Hi, If the error message persists or the machine cannot leave HomeGroup, please try the following steps. Leave HomeGroup completely a. Click the Start Button, type "cmd" (without quotation marks), in the search result list, right click on Cmd.exe and select Run as administrator. Note: If you are prompted for an administrator password or confirmation, type your password, or click Continue. b. In the popup window, type the following commands and press Enter one by one: Net stop p2pimsvc 2. Access t he following folder and clear all files inside: C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\PeerNetworking 3. Click the Start Button, type "cmd" (without quotation marks), in the search result list, right click on Cmd.exe and select Run as administrator. Net start p2pimsvc Then, please recreate HomeGroup and change password again. Thanks, Novak
