delete localization from windows

I'm writing a post in order to see whether there is some interest in a little script I am writing...
I saw that in Linux there is the nice localepurge script, and the good BleachBit program. The aim of these two programs is to delete useless localization files... if you don't plan to ever use man pages, help pages, program localizations from some foreign language you're pretty sure you won't ever learn, why should you keep them?
The matter is, not only these localizations occupy space, but they also waste time when performing backups, when checking the disk for errors (at least, with NTFS) and so on... so I want to see whether it is possibile to write something similar for windows, but being prudent in order to avoid serious damages.
If someone is interested in this, please tell me... I'll write this script at least for my personal purposes, as this is very risky it won't ever be directed to the general public, it's better to be well aware of its possible problems.
