Here’s a quick overview of how I upgraded my custom MS4W binded with ColdFusion..

1. Extract the new ms4w_new.zip to E:\ms4w_new

2. diff E:\ms4w_new\Apache\conf\httpd.conf E:\ms4w\Apache\conf\httpd.conf

If the changes is minimal, then proceed.

3. Uninstall ColdFusion connector from Apache.

4. Uninstall Apache from services.msc. Run

E:\ms4w\apache-uninstall.bat

5. Move

mv E:\ms4w E:\ms4w_old
mv E:\ms4w_new E:\ms4w

6. Install Apache as a windows services to services.msc

E:\ms4w\apache-install.bat

7. Bind ColdFusion again to Apache
