This neat tip, Jamel provided us, avoids headaches when using the command prompt console. It'll turn on the auto-complete feature so when you type 'cd d' and hit the tab key, the console will display the list of folders that begin with the 'd' letter, and you'll be able to choose the one you're looking for, right from the console instead of typing its path.
Log on as Administrator,
Click Start, and then click Run,
Type Regedit and OK,
Double click HKEY_LOCAL_MACHINE,
Double click SOFTWARE,
Double click Microsoft,
Double click Command Processor,
In the right pane of Regedit, double click the 'CompletionChar' DWORD value,
Type 9 click OK,
Close Regedit,
Click start/programs/accessories/command prompt,
Type 'cd d' and hit the Tab key: the first folder that matches the 'd' letter is displayed (you can switch from folders pushing several times the Tab key).
