Add-Remove Programs Editor* ~ Forum Topic Updated: 10/3/07: Ever wondered how the Add-Remove Programs control panel applet gets its information? It seems like the sizes, frequency of use, and even the icons are often wrong. This article explains how the info is calculated; and this Add-Remove Programs Editor will let you alter the fields, including Name, Icon, Size, and Frequency of Use.
Dual Display Toggle* ~ Forum Topic Updated: 10/25/07: This little tool replicates the functions available on the Settings tab in the Display Properties Control Panel. It can extend the Windows desktop onto a second monitor, plus alter screen resolution, color quality, and refresh rate. A similar script with oodles more features can also be found here.
MRU* ~ Forum Topic Updated: 12/29/07: In response to a help request, I wrote this short script to display Windows' most recently used documents in a list view. It isn't particularly robust as-is, but is rather a framework for a script to display more comprehensive info about recent documents and potentially perform actions on them.
IP Toggle ~ Forum Topic: When I'm at home I use a static IP address on my laptop, but when I'm on the road I often need to switch to DHCP (Obtain an IP address automatically). I run this script to toggle back and forth between the two settings. It saves time versus manually entering the data. So far the script is tailored specifically to my needs, but it could easily be adapted to other environments.
