I've had this happen several times on Windows 10 recently: while using CCleaner Pro cleaner, it wants to stop Microsoft Edge, which isn't running, and I say yes. CCleaner says it's taking a long time to close Edge, do I want to force close Edge? I say yes and after the cleaning, while using Edge, I get a BSOD. Are the two connected, forcing Edge to close and the BSOD? The Windows blue screen troubleshooter says the Windows Store cache may be damaged. For now I close Edge with the Task Manager before using CCleaner, but I'm not using Edge again till I know more.
