I am writing this to ask you to add a necessary feature into the upcoming release of CCleaner 4.0. You should add a feature that kills the process of a file you are trying to alter/delete but says you cannot because it is open by another program or process.
I think this is an interesting request. Something similar is already implemented with Browsers, but I think that it may be difficult to implement systemically, or may attempt to end system-crucial processes.
Interesting. But for CCleaner to combat a longtime Windows issue, I don't know because even file process ending tools can have issues trying to unlock files that Windows has a a vice grip on.
