TweakUI allows you to “tweak the UI, the User-Interface“, to fine-tune the display and some
operation, including some networking options (and therefor I include it n my website).
TweakUI has a long history:
First part of the Windows95 PoyerToys available as download from the Microsoft website as
“unsupported” utility, it was included on the Windows98 first edition CD-ROM, but not anymore
on the Windows98 Second Edition CD-ROM or on Windows ME.
Also the download locations on the Microsoft website has changed several times, so the
information below ( valid on Oct 21, 2000 ) may change in future, but today it is:
Tweak UI 1.33http://www.microsoft.com/windowsme/guide/tweakui.exe
