What the #### is going on with Windows 10???

First, a problem appeared whereby at random times my dialogue boxes would be rendered unreadable by black lines. This situation suddenly appeared, and despite much help from Dalchina and the lovely people on this forum, persisted through many resets/reinstalls etc. until, just as miraculously, it stopped and (touching lots of wood) hasn't returned for a week or two.

This problem was swiftly replaced by an equally randomly occuring event where File Explorer would take ages to open anything ("working on it") at all, and, after eventually finding the drive/file requested, would crash when asked to open/move/save/save as that item.

That seems to have worked its way out to be replaced by the latest problem.

Again, really randomly, File Explorer will suddenly crash, give a "white screen" for a couple of seconds, then close down altogether. Looking at Event Viewer I can see an Admin Error that says:

The program explorer.exe version 10.0.14393.0 stopped interacting with Windows and was closed. To see if more information about the problem is available, check the problem history in the Security and Maintenance control panel.

I don't understand what I am looking at in this log (or where to look next) but if anyone can explain/help I would be most grateful.

The cynic in me is wondering if there is a group of "experts" at Microsoft who have created a menu of problems that they are releasing, one at a time, to see how upset and angry we, their customers, get!!!
