Windows Update (hereinafter referred to as Wu) always prompts a 80244019 error (for example) when checking for updates, and notices the message "managed by your system administrator" at the bottom of the window ", it is estimated that Wu cannot connect to Microsoft for updates because of the Group Policy deployed by domain control on all computers.
Next, we will see a "check online for updates from Microsoft Update" link. This should be another way to deal with the inability to connect to Microsoft updates. After clicking this, Wu starts searching for updates.
However, it is also very troublesome to do this every time. domain control must modify some registry locations when deploying the Group Policy to make Wu unusable. So you can solve the problem by finding them and modifying them. I found something windowsupdate in the policy.
[HKEY_LOCAL_MACHINE \ SOFTWARE \ Policies \ Microsoft \ Windows \ windowsupdate]
1. Click windowsupdate. If WSUS is deployed in the domain controller, its settings will be shown here: wuserver and wustatusserver, both of which contain the address of the WSUS server in the domain, do not delete it. (It is best to back up the data first. Don't be reckless ...).
2. Let's take a look at what is in Au under windowsupdate. Here, we also store some group policy settings parameters. In particular, we noticed that usewuserver should be used to tell Wu where to find the Windows updated parameters, set the data value to "0.
Restart and check the result. Wu is restored to its original state:
3. In fact, compared with a non-domain computer, if the Group Policy has not been modified, there is no windowsupdate directory in the registry, that is to say, it is also possible to delete all [HKEY_LOCAL_MACHINE \ SOFTWARE \ Policies \ Microsoft \ Windows \ windowsupdate]. It turns out that all deletion is correct. Add a Reg for deletion.
