I recently got a blue screen on a Windows XP machine with the following error code: STOP 0x0000007F (0x0000000D 0x00000000 0x00000000 0x00000000) I wanted to find out what went wrong. This is what Microsoft has to say on the issue: This error message can occur if either of the following conditions exists: * Your computer […]

Vor einiger Zeit habe ich ja bereits über eine einfache Backuplösung für Windows mit RdiffBackup (jetzt HardlinkBackup) geschrieben. Diese funktioniert für mehrere Rechner meiner Familie ganz hervorragend. Das verbleibende Problem war jedoch, dass der Benutzer regelmäßig daran erinnert werden sollte, ein Backup anzufertigen.

Bei Windows XP ist die Situation leider eine andere: Es gibt zwar das Programm ntbackup, das sich auch bei WinXP Home nachinstallieren […]

This software can be used (amongst others) for configuring BIOS and hard disk “passwords” based on smartcard authentication. This is a nice feature, but what if you try to turn this off again after trying it out? […]
