In the "Why Do I Need?" part, maybe "reason," "require," "benefit" could be synonyms.
I also need to check for any words that might be part of proper nouns. For instance, "Windows 7, Windows 8, Windows 10" should stay as is. Words like "Intel" and "AMD" are proper nouns too.
Given the ambiguity, I'll proceed by identifying each key term in the original text and providing three synonyms for each in the opt3 format, leaving the original names as they are. I'll compile these as a list.
In the "What is Siemens PLM License Server?" section, terms like "manages licenses," "central repository," "access," "utilize," "concurrent users," "allocated licenses" need synonyms.
