Four blocks bottom left

Using Windows10. When I open the square at the bottom left of the screen, normally I get a (ladder) list of items installed in my computer but all of a sudden, all I get now is a list of squares which show minimal information. I have been unable to find Windows Accessories to make a screen shot as i cannot find where the program is!
Can anyone please explain how I can put the problem to rights please?

Small White Square in Upper Left Corner - Cannot Remove

This is going to be hard to see, but above the left of the recycle bin icon... there is a tiny white square. When I put my mouse cursor over it I get the cursor to change to the activity cursor (spinning blue circle) - I have no idea what application is causing this and have stopped all tasks starting with windows on boot.

Any ones else ever see this?









HP Spectre Laptop with latest BIOS as of this post installed. All windows updates.

 

Gray Square on Desktop - Frozen Cursor

Here's today's update.

Starting with yesterday, uninstalled all of my recent Windows Updates and any other Update from any other application (mostly Adobe) and then I did a clean boot start. Got thru that fairly quickly (remember, I am technically challenged) but I got 'er done
and when the laptop restarted, the issue was there again. The laptop automatically started to download and install the latest Windows Update and I didn't stop it. I uninstalled a few programs and shortened by startup list of apps, still the square and gray
circles were there. I then ran a series of malware and virus scans from various apps all resulting with no issues. I also had a 'Fix Me Stick' which I ran and resulted in nothing to fix. So worked through my day, swiping the square and gray circles away from
my display until I went to bed last night.

This morning, I started up the Dell and began working - but no square and no circles. I worked all day on the laptop using Photoshop, PowerPoint, Word, Outlook, Excel and NO SQUARE AND NO CIRCLES ALL DAY!

I do not know what has happened nor what fixed this issue but it suddenly has stopped. I will watch if the 'crop circles and square' returns and if so, I'll update this question again.

Thanks to all who contributed with possible solutions and corrective action steps for me to follow. All contributions and suggestions were and are gratefully accepted and very much appreciated.

Cheers!
