Hashing .exe names is way too much work. Since Vista Microsoft has provided an opt-in way for a game installer to optionally flag &quot;Hey, I&#x27;m a game&quot;. This was used for the mostly useless &quot;Games Explorer&quot;, but also little bits of other functionality.<p>Also, the Microsoft Store has an entire category called &quot;Game&quot; and can just use that.<p>Worst case though, by &quot;game&quot; it might just use the Window&#x27;s Xbox app&#x27;s determinant for shortcuts like Win+G which is essentially, from what I gather, &quot;Does it use DirectX? y&#x2F;n&quot;.
