LTSC Versions not recognized in all languages
The LTSC OS checks do not fully cover all cases, e.g. for Chinese computers, the OperatingSystem attribute could be "Windows 10 企业版 2016 长期服务版", which does not contain LTSB/LTSC in the name but still is a valid Long-Term Service OS.
Regrettably, I am not aware of a full list provided by Microsoft or any other source, and I do not know if there are other ways of writing LTSC/LTSB with Chinese letters. Nonetheless, please add at least this check to the code. If my skills with Google Translate are enough, then "长期服务版" should suffice for the check, as this seems to be the equivalent of LTSC/LTSB.
