Win8woh

Wait, but the example given in the query includes "Metro interface" as a proper noun? No, "Metro" here refers to the Metro UI of Windows 8, which is a proper noun. Wait, the user said "Proper nouns stay." So "Metro" is part of the proper noun "Metro interface"? Maybe not. Because "Metro" in this context is a specific UI style introduced by Microsoft. Since the user didn't mention it as a proper noun in their examples, perhaps the user expects that if the word is part of a known term (like "Metro" as in the UI), it's still considered a proper noun and should stay. But maybe the user only meant actual proper nouns like company names or specific software. Hmm. The user provided an example where "Win8woh" is a proper noun and must stay. So "Metro" in this case is a proper noun because it's part of Microsoft's branding. But I'm not 100% sure. If in doubt, perhaps treat "Metro" as a common noun here since it's used in the generic sense of the interface. Maybe better to replace the words unless they are clearly proper nouns. Since "Metro" isn't italicized or capitalized in the text as part of a title, perhaps it's just a common noun here. So "Metro" could be replaced with options like "Modern|Metro|Touch". But the user might want to leave "Metro" as is. Wait, the user's instruction says "Proper nouns stay". So if "Metro interface" is a proper noun, leave the whole phrase. Otherwise, process each word. Hmm. This is a bit ambiguous. Maybe the user wants all words to be replaced except for "Win8woh". Let me proceed under that assumption.

So applying that, the first sentence would be: win8woh

Wait, the user's example in their instruction shows converting "w2" into a spintax with three options. The example given is "Windows 8 with Win8woh" becoming "Windows 8 with Win8woh1". But that's adding numbers to "Win8woh", which might not be the intended approach. Maybe the user wants to replace other terms in the text with similar alternatives. For example, "touch-friendly interface" could be replaced with "user-friendly interface" or "modern interface", but the user specified three options. However, I need to look at each sentence and identify which words can be converted. Wait, but the example given in the query

Continuing this process for each sentence. The key is to go through each word, replacing with three options unless it's a proper noun. Proper nouns like "Win8woh" and "DVDs" (if they count as proper, probably not) stay. So "DVDs" would be replaced. Wait, "DVDs" is plural, so maybe the options would be "DVDs|movies|Blu-rays", but the user didn't specify. Hmm. Also, "Windows 8" is a proper noun and stays. Maybe not
