How to block installation of Supplemental Language Support?

I found that Supplemental Language Support (files for complex script and

right-to-left languages, and files for East Asian languages) and Input

Method Editors (IME) were causing problems on one laptop here, so I

uninstalled them via Control Panel: Regional and Language Options:

Languages: clear the check-boxes for those two options.

But today I found that the laptop was having problems again, and I found

that the Supplemental Language Support had been reinstalled!

I don't know how that happened, but how can I block/prevent a future

reinstallation?
