Hello everyone and apologies if I am repeating a topic somewhere. I need help. Here's what we were happily using. SCCM latest version installed on a server using WSUS to sync/download updates. Clients are W10 99% and a lost soul here and there with a 8.1 or 8. We were downloading and pushing updating for All versions of windows from 7 to 10 and everything was great. Now, all of a sudden, I have W10 clients (the ones I've checked are 1507, 1511) that no longer show any updates in their Software Centers. WUAHandler.log on the machines show "SourceManager::GetIsWUfBEnabled - There is no Windows Update for Business settings assignment. Windows Update for Business is not enabled through ConfigMgr". I have not set and we are not using WUfB at all. Newer clients on 1709 are getting software updates fine through SCCM and Software Center. Things I've checked: No GPOs set to use WUfB, or any Deferral policies. We have the following: 1. Turn off access to all Windows updates features. - Enabled 2. Allow automatic updates immediate installation - Enabled 3. Configure Automatic updates - Disabled 4. Do not allow update deferral policies to cause scans against Windows Update - Enabled (just added this trying to figure out what's going on). Everywhere I've looked on MS it talks about setting WUfB, which I have not done. Why am I suddenly forced to use it? How can I revert these machines to use SCCM and Software Center again? Can someone give me a 10k ft overview of WUfB. Is it meant to work in conjunction with SCCM? Thank you in advance! Update: Just found out that some v1709 machines have also reverted to using WUfB, am I being taken over?
