Windows

Since I always use some GUIs, I don't really remember anymore how to connect to a Windows machine via the command line. smbclient -L windowshost shows you the shares that are available. Often, you you cannot browse them without a login/password for that windows machine, therefore you need to type smbclient -L windowshost -U username And occasionally the netbios name doesn't work either and you need to replace it by the IP address.

Press the PrtSc button (somewhere near PageUp/Down) to capture the whole screen and Alt PrtSc to capture the active window only. Then Open Paint (from Programs, Accessories), paste and save.

I was fighting for several days to delete a file in Windows XP that started with dot underscore (._). The message was always: "The system cannot find the path specified". Nothing worked. No safe mode, no command line, no special syntax. The Microsoft Knowledge Base addresses the problem, but instead of pointing to an easy solution it gives lots of useless and even wrong information, e.g the Windows XP Resource Kit didn't contain the RM.EXE program, that was supposed to be able to delete those files with "weird" file names.
