It seems like you're facing an issue with setting up a homegroup after upgrading to the RTM version of Windows. The error message you're receiving, "Windows cannot set up homegroup on this computer," indicates that there might be some specific reasons causing this problem. Here are some possible reasons and solutions for why you are unable to create a homegroup: 1. Network Discovery and Homegroup Connections: Ensure that the Network Discovery and Homegroup Connections settings are turned on. To do this: - Go to Control Panel > Network and Sharing Center. - Click on "Change advanced sharing settings" on the left panel. - Make sure that "Turn on network discovery" and "Turn on file and printer sharing" are enabled. 2. Homegroup Provider Service: Check if the Homegroup Provider service is running. To check and start the service: - Press Win + R, type services.msc, and press Enter. - Look for the HomeGroup Provider service in the list. - Right-click on it, select Properties, and ensure that the Startup type is set to Automatic. If it's not running, click Start to initiate the service. 3. Troubleshoot Homegroup: Windows has a built-in troubleshooting tool that can help identify and fix issues with creating a homegroup: - Go to Control Panel > Troubleshooting > View all. - Select HomeGroup from the list and follow the on-screen instructions to run the troubleshooter. 4. IPv6 Protocol: Homegroup heavily relies on IPv6 protocol for sharing. Ensure that IPv6 is enabled on your network adapter: - Go to Control Panel > Network and Sharing Center. - Click on your network connection, then click on Properties. - Make sure that Internet Protocol Version 6 (TCP/IPv6) is checked. 5. Check Firewall Settings: Sometimes, the firewall settings can block Homegroup connections. Try temporarily disabling your firewall and then attempt to create the homegroup again to see if the issue persists. Try these steps to troubleshoot the issue with creating a homegroup on your RTM version of Windows. If the issue persists, let me know, and we can explore further solutions.
