How does one install glass block for windows?

Some notable Windows XP features and components have been replaced or removed in Windows Vista. Perhaps the most significant of these is the removal of Windows Messenger, the network Messenger Service, Hyperterminal, MSN Explorer, and the replacement of NetMeeting with Windows Meeting Space. Windows Vista also does not include the Windows XP "Luna" visual theme, or most of the classic color schemes which have been part of Windows since the Windows 3.x era. The "Hardware profiles" startup feature has been removed as well, along with support for older motherboard technologies like the EISA bus and APM. Also WinHlp32.exe, which was used to display 32-bit .hlp files is no longer included in Windows Vista as Microsoft considers it obsolete. This has resulted in a number of older programs not being able to display Help when running on Vista. In addition Microsoft also prohibits software manufacturers from re-introducing it with their products. However, the program can still be installed manually from Microsoft's Download Center.
