Today when I executed ‘Check for available updates’ with server selection set to ‘Windows Update’ I received the following error on my Windows 10 v1607 machine:
-102: Failed to execute the search. HRESULT: -2145107921
This error is equivalent to:
0x8024402F -2145107921WU_E_PT_ECP_SUCCEEDED_WITH_ERRORS
I have never seen this error before today, and things were working fine two days ago with the exact same settings. The only thing that I did between two days ago and today was install the ‘Meltdown’ patch that Microsoft published on Jan 3 2018 KB4056890.
My computer is opted-in to ‘Microsoft Update’ and if I switch the server selection radio button to ‘Microsoft Update’ the check for updates works fine, but as soon as I switch back to ‘Windows Update’ the check fails again with the error above.
