I have a Windows 10 (went through all of the Insider builds) and have a dozen languages that ended up in Optional Features (without my knowledge) that cannot be removed. Those languages (Chinese, Swedish, etc.) have only "Manage" button which does nothing. In Control Panel -> Languages I have only English and Bulgarian.
I see that there are two places for language packs to install - System32 and SysWOW64. The contents of SysWOW64 is what corresponds to the list in Settins -> System -> Apps & Features -> Optional Features.
I've read on other forums that there was a bug around builds 1004x that could lead to large install times and the addition of many LPK (language packs). And indeed, my RTM install took a good whole night to complete.
So far I have:
- used Lpksetup /u and uninstalled everything there but English. This removed only the languages from System32 but had no effect on SysWOW64 and what is listed in Optional Features.
- have added the languages listed in Optional Features in Control Panel -> Languages so that I can uninstall the language packs from there, but the option available is to Download and install the pack and not to uninstall it
- With #2 in mind, I have downloaded the corresponding language pack in Control Panel -> Languages and have then uninstalled it - Optional Features still list it
How can I remove those languages?
