Every time I put my laptop to sleep and have a Windows Explorer window open, the CPU goes to 100% for several minutes after waking up the computer. If I wait for a long time, it will eventually go back to normal, but most often I close all the Windows explorer
windows, manually or using Task Manager, and reopen them again to get to a normal CPU working load. I have not been able to identify clearly with process explorer what is causing this, although SHCORE.DLL is one of the suspects. Searching on Internet I have
surprisingly not found many similar cases, so I do not know how to proceed.
Running sfc gives a few errors, which do not seem to be possible to repair, but I doubt it has anything to do with this problem.

I have checked the files at virustotal.com, and no virus has been detected.
As far as I remember this laptop has always behaved like this, so I cannot relate it to any specific update or installation. Moreover I almost only use portable apps, which normally should not mess with system settings.
Any ideas of how to proceed to find what is causing this very annoying error is very appreciated!
The computer is an Acer Aspire E13, still running Windows 8.1. (I upgraded temporarily to Windows 10, but the error as described above was still there.)
