Can't open file 'django-admin.py': [Errno 2] No such file or directory

I'm using Python 2.7, Django 1.2.5 and on Windows 7.

I am not sure what I've done. I used to be able to create Django projects like

python django-admin.py startproject test

Now however I get this error.

Can't open file 'django-admin.py':
[Errno 2] No such file or directory

I can type the following which works.

python C:\Python27\Scripts\django-admin.py startproject test

How can I have it the way it used to be? Not having the type the full path to the django-admin.py file.

Things I've already tried:

I uninstalled Python and manually removed the values from the PATH variable in Windows. Reinstalled Python. Deleted Django and reinstalled it too.

I've added C:\Python27\Scripts to my PATH and PYTHONPATH variable under Environmental Variables in Windows.

Any suggestions?

My PATH variable contains

C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;C:\Program Files (x86)\ActiveState Komodo Edit 6\;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\django-apps;F:\My_Projects;C:\Program Files (x86)\QuickTime\QTSystem\;C:\Program Files\TortoiseSVN\bin;C:\Program Files\Mercurial\bin;C:\Python27;C:\Python27\Scripts

PYTHONPATH has

C:\Python27;C:\Python27\Lib;C:\Python27\DLLs;C:\Python27\Lib\lib-tk;C:\Python27\Scripts;C:\django-apps;f:\my_projects
