Scripting

Extending the use of your grey matter would provide you with the clues you need to progress this.

- Download and start a registry monitoring program. If you don't already have a process/file/registry monitoring tool, get one. This job (or indeed any kind of support role) will be immeasurably harder without one. ProcMon is my personal favourite.
- Turn the 'Hide files' option on and off in Explorer
- Note down the registry value which Windows changes as you turn it on and off.
Note:
Because Windows is particularly stupid, it will re-write ALL the Explorer options, even the ones you didn't change. However, your monitor will show you the registry key beneath which these values are stored. And yes, I know what that value is, but I'll leave you to find it yourself.
- Find a registry-changing script using this new fangled search thing called 'Google'. In fact, seek out cRegistry.cls, a class file which you can include with your scripts for use here and in the future. You'll thank me. Eventually.
- Edit the script to suit

Indeed, or capture the changes with a tool (like wise) then a RegWrite will do the work
