When I hit Clean Now, it advised me which files on the list I ought to keep, which I was able to do by selecting to Ignore each of them. It exposed programs I thought I had completely uninstalled (like iTunes, uTorrent – which gave me a few headaches with persistent Conduit PUPs) and others that I didn’t know took so much space.
Altogether, +5GB of stubborn crap was sent flying out the window.

What a joy to find one program that does what it says on the tin: FREE JUNK CLEANUP.
Not “free-download-but-cough-up-the-cash-if-you-want-to go-the-next-step.”
Not just your Temp or Bog-Standard Junk Files that I can remove with most cleanup tools, but the really stubborn Junk Files that CCleaner could not sort out, nor the inbuilt Disk Cleanup Windows Tool, nor Free Disk Space (even using the 30-something Passes Option, which takes days to go through and never got me any closer to ridding me of those pests) or anything else that I found for free.

I need to clean my laptop, not my phone.

Of course it does, Android is the majority of os for phones out there
