Windows 10: Startmenü öffnet sich nicht, Info-Center ebenfalls nicht…

Microsoft lässt seine Nutzerschaft mal wieder im Regen stehen, wenn das im Titel beschriebene Problem auftaucht. Den PowerShell-Befehl zur Reparatur findet man nur in diversen Foren, etwa hier und hier:

Get-AppxPackage | % { Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppxManifest.xml" -verbose }

Dann sollten Startmenü und Infocenter wieder erscheinen und funktionieren.

"Fun" with Funambol….

Sadly there seem to be no „official“ Funambol add-ons for newer Thunderbird versions. No matter using official or inofficial add-ons (for example those provided by memotoo.com), debugging strange errors isn’t really fun. For example the nice message „Error: code 2054“ when trying to sync a new client:

funamvol error code 2054

The log files don’t offer any more information. Searching the web doesn’t help, either, but the error seems to be caused by an SSL issue. In fact, i tried to access a (custom) Funambol server using https, and the SSL certificate was cacert based. Ok, but i’ve imported cacert’s root and class3 certs into Thunderbird’s cert cache already? Finally, i realized that the Funambol add-on just ignored the certs in the Thunderbird cert store and solely checked the root certificates provided by windows! After importing cacert’s root certificate in the windows cert store (take care to choose the right „department“ – you have to manually select „trusted root certification authority“ – or „Vertrauenswürdige Stammzertifizierungsstellen“ in german…), everything worked like a charm.
