Here's a slightly convoluted way of doing it.
1 - Open Notepad.
2 - Write: "explorer.exe c:temp" (without the quotes), but change the "c:temp" part to whatever you want to be the startup folder
3 - Save the file, but on the save file dialog, change the file type from "text file" to "all files". The file name should end in ".bat", I called it
4 - Create a shortcut on your desktop or in your start menu, pointing to that "whatever.bat" file you just created.
5 - Right-click on the shortcut and choose "properties". In the "shortcut key" field, choose a key combination (like ctrl + alt + e, for example) and
Now, if everything is as it should be, if you press the key combination you just defined, the explorer will open in the desired folder.
This method, instead of the "whatever.bat" file could use a simple shortcut to that folder, as Skada
said. You can also add a shortcut key
combination to that shortcut. The only advantage of the method I mentioned has is that you can use it to open two or more folders, you just have to
add another line with a command to open the second folder. This is useful if you usually copy files from a folder to the other.
PS: as I don't have an English version of Windows the names may be different.
