Plea to developer -- fully portable TLBhost

This toolbar looks like the standard Windows Quick Launch. Generally nothing must be lost after windows update. I guest your TLB have been switched into other toolbar folder (standard Windows Quick Launch).
If this is the portable version, then try to right-click toolbar and select your toolbar from the "Switch Toolbar" submenu. Also, check if the file named "portable" is exist in the same folder as tlbHost.exe, and create empty file if it is not exists (restart TLB after creating.)
