I've dealt with error code 0x80072efe on a Windows 7 system before, and it can definitely be a bit frustrating. This error often stems from connectivity problems, usually related to network settings or interference from security software.
Here are a few steps you might try that have worked for me in the past:
Ensure Your Network Is Stable: Make sure your internet connection is active and stable. Sometimes, a simple reset of the router can help resolve intermittent connection issues.
Adjust Proxy Settings: Go to Control Panel > Internet Options > Connections tab > LAN settings, and ensure that the "Use a proxy server for your LAN" option is unchecked. This can resolve issues if incorrect proxy settings are blocking the connection.
Flush DNS and Reset Network Settings: Open the Command Prompt as an administrator, and execute the following commands one by one:
Temporarily Disable Security Software: Sometimes antivirus or firewall settings can block the necessary connections. Try disabling them temporarily to see if it clears up the issue.
Manual Update: If nothing else works, you can download specific updates from the Microsoft Update Catalog. Simply search for the update you need by its KB number and install it manually.
Considering that Windows 7 is no longer supported, you might also contemplate updating to a newer version of Windows to ensure smoother functionality and better security. For immediate issues, however, these steps should help you out. Let us know if any of these suggestions work or if you find another solution!
