Right now there are 3 Windows 7 tags, plus a synonym:

 - Windows7 (synonym for Windows-7)
 - Windows-7 (1265 tags)
 - Windows-7-64 (43 tags)
 - Windows7-32 (6 tags)

Should we merge the 32bit and 64bit tags into the Windows-7 tag? If not, at least cleaning up the formatting discrepancy would be helpful.
