The most effective method to fix Windows Explorer not responding is to clear file explorer history. You can open on Control Panel, set view by large icons and click File Explorer Options from the interface. Then click Clear button and OK to clear Windows Explorer history. Then try opening Windows Explorer again.
If the issue has been occurring for a month or more, it may be better to perform an In-Place Upgrade and restore Windows to the original installation. Performing an In-Place Upgrade will not damage files and applications that are currently installed on your computer.
