Hmm, seems you're right.
Was always just a community belief that Snipping tool was registered with the Tablet PC Components since Vista. Even though there doesn't appear to be any hard statement saying so from MS. They do kind of off hand
mention the relation.
Was the same belief for StickyNotes as well, but that doesn't appear correct either. Missing Snipping Tool in Windows 7 - Insufficient data from Andrew Fryer - Site Home - TechNet Blogs Snipping Tool Missing Snipping Tool
If you googled with the keywords - Tablet PC Components snipping tool, and a search here of SF, you could see that belief has been around for years all over.
But it appears if it was tied in with Tablet PC Components in Vista, it doesn't appear that way anymore with Win 7.
News to me. Snipping Tool removed Snipping Tool removed
