Windows Update Broke LocalHost This Time

THEY CAN'T KEEP GETTING AWAY WITH IT 😩 Yet another Windows 11 update has caused issues, this time fortunately it was identified and patched very quickly via a rollback. The problem it caused seemed to be with apps that used the HTTP/2 protocol, which isn't quite as common as regular old HTTP, but still common enough. And apparently it especially affected apps that used "localhost" to connect within the same computer, but I think it affected other apps too. Here's the command with the shortcut in the bonus tip I mention at the end: powershell.exe -command "& {Update-MpSignature -Verbose; pause}" Time Stamps: 0:00 - Intro 0:24 - Details About The Bug 1:24 - The Fix 2:01 - Other Possible Fixes People Mentioned 2:32 - What The Fix Actually Does 3:23 - Bonus Tip: Security Definitions Update Shorcut
