You'll need Resource Hacker to modify these files.

So here is a list of various system files in Windows 7 which can be easily hacked using Resource Hacker:

Approx. all Windows 7 system icons

-> %windir%\System32\imageres.dll

Login Screen Background

-> %windir%\System32\imageres.dll

Login Screen image resources

-> %windir%\System32\authui.dll

Startup Sound

-> %windir%\System32\imageres.dll

Start ORB images

-> %windir%\Explorer.exe -> Bitmap -> 6801 - 6812

Windows Version Image in "About Windows" dialog box

-> %windir%\Branding\Basebrd\basebrd.dll

Windows Version Image in bottom of Login Screen

-> %windir%\Branding\Basebrd\basebrd.dll

Control Panel Left Sidebar Image

-> %windir%\System32\Shell32.dll -> Bitmap -> 632 & 633

Getting Started (aka Welcome Center) Images

-> %windir%\System32\oobefldr.dll

Laptop Battery Meter image resources

-> %windir%\System32\batmeter.dll

Internet Explorer 8 (IE8) Resources

-> %windir%\System32\ieframe.dll

Windows Media Player 12 (WMP12) Resources

-> %windir%\System32\wmploc.dll

Above mentioned system files/locations are new to Windows 7 and were not present in earlier Windows versions, like XP. If you want to change look of other menus, dialog boxes like RUN, Progress, System Properties, Start menu, Taskbar Properties, etc, you'll have to edit some other system files which you needed to edit in Windows XP But there is a little difference, now those files don't contain the resources but their .MUI files do.

For example in Windows XP, RUN dialog box resources were present in "%windir%\System32\Shell32.dll" file but in Windows 7, the resources are present in "%windir%\System32\en-US\Shell32.dll.mui" file.

All these .MUI files are present in any of following 2 locations:

%windir%\en-US\

%windir%\System32\en-US\
