Unlike windows XP, you cannot replace a Windows system file in vista or Windows 7, unless you have administrative privileges. Microsoft has introduced this to prevent accidental overwriting of windows system files, which may lead to unpredictable system performance ranging from application errors to operating system crashes. System instability caused by non-standard replacement of system files was a common problem faced with earlier versions of windows.
However, there may be instances where you would want to replace Windows system files. For example, to install custom themes in Windows 7, Vista and Windows XP, you need to patch Uxtheme.dll (theme manager dll), themeui.dll and themeservice.dll. All these files are located in the system folder – C:/windows/system32. Patching these windows system DLLs would require you to replace the Windows system files with the patched (modified) files.Once you patch up the three DLLs, you may be able to install any custom theme.
