Hi all,
  1. Windows 10 File Explorer Slow To Open Windows 10

I've been running the same PC now for 6+ years, have never reformatted and never had a problem. I've been noticing over the last few week however that file operations (opening folders, renaming, copying, etc.) have a very noticeable lag in Windows Explorer. First I thought it was a HD that was about to pooch, but it's a system-wide problem, even happening on my SSD.Message
Only thing I've changed recently was RAM. Upgraded from 8GB DDR3 Kingston to 16GB DDR3 Kingston - bought a brand new 8GB kit and removed the previous 4GB kit.
What I've tried (all reported no problems):

  • Western Digital Data Lifeguard scans
    SFC Scan
    DISM Scan
I was thinking about finally doing a fresh Windows install, but since the scans found nothing, I'm wondering if may to problem isn't software-related? Is there anything else I can try before going down the reinstall road?
Is my RAM/CPU combo ok? I've seen a few posts relating to certain RAM sizes and the I7 chipset, but it's a little too technical for me to understand.
