Solved Single click now too fast

I've uses mouse single click for years. Hovering over an icon or file selects the item, just like a single, click, then a click opens it. Recently, the delay between hovering over something and it being selected has got much shorter. This is a pain because selecting an item in explorer then moving the cursor to the ribbon to delete or cut or paste now frequently selects whatever I am moving the cursor over to get to the ribbon. Is there a way to tweak the delay time before an item gets selected?

I would check MouseHoverTime and MenuShowDelay.
P.S. You need to restart explorer.exe between changes.

Thanks @TairikuOkami editing MouseHoverTime fixed it :) I had to increase it quite a bit but now working as I want it.
