Windows 10: White homescreen, no taskbar, hourglass cursor, unresponsive keyboard, redundant warning

Hello, I am using my ThinkPad laptop with Windows 10 installed. I am currently facing an issue where the entirety of windows has become unresponsive. I am looking at my homescreen which shows all of the apps present on my desktop. Behind it is a white background which is normally not like so. My bottom taskbar is gone and my cursor is an hourglass everywhere I move it. With every click or keyboard press I get the same pop-up windows with the subject title "Microsoft Windows" reading "The application is not responding. The program may respond again if you wait. [Space] do you wish to end this p

:)

 

Hourglass on cursor

Hi Black,

An hourglass on your cursor, generally means your PC is busy - is your PC sluggish when the hourglass is on your cursor?

If so

Open Task Manager (Ctrl + Shift + Esc)

Are any of your devices (CPU, RAM, DISC . . . etc.) very busy or up to 100%

 

Hourglass on cursor

I've read and tried the various ways to get rid of the hourglass on my cursor. Its not there all the time but it annoys me. I've tried the Settings way through but that doesn't work and I've also tried the Lenovo Settings to ensure that both are in line
with each other. but still it persists. I've also tried the troubleshooters but they don't deal with it. Anyone got any ideas please?

 

hourglass cursor will not stop flashing

I just installed windows 10 on my Windows 8.1 PC and it was fine for a while, but when I logged in the next day, the cursor began flashing the hourglass to its right and it has not stopped. It interferes with drop down menus which only remain open for
a millisecond before vanishing. It stops videos as though they're buffering and the taskbar flashes on the screen when I'm playing them fullscreen. I've tried rebooting my PC numerous times and I've tried everything suggested in previous help threads on here
(and elsewhere), but they've all been either unsuccessful or irrelevant as each one is specific to Win8, 8.1, or 7. I've done numerous antivirus scans with Sophos, which I thought had been uninstalled due to being incompatible with Win10, but they've found
nothing. I've tried ending all the possible tasks that could be responsible. This is driving me nuts and I had no problem on Windows 8/8.1.
