Blinking/Flashing Icons on Desktop PC

Hi:

I am experiencing blinking/flashing of several icons that are located on my Win10-64 Pro desktop PC's screen and icons that are pinned to within the taskbar. The PC is a DELL XPS 8700 desktop. I think my PC has Windows 10 version 1803 installed on 5/19/2018, and am getting updates automatically from Microsoft.

Observations:
When booting the PC, after the login screen, it is taking an unusual amount of time to load the "image" part of the desktop icons; the filenames in text appear first and quickly, and then a delay occurs before the icon images are "painted" onto the monitor's screen. I also noticed that while having file manager opened, the same file names blink in the directory structure pane, at the far left. Just now noticed, as I am writing this, that while using Internet Explorer browser, blinking has stopped, taskbar icons have disappeared and replaced with blank, box outlines, no response when clicking on a desktop icon; this happened once before and I had to reboot PC to get control of taskbar back.

What I have tried thus far and results:

1. I ran the inbuilt DELL diagnostics, and all hardware passed the "thorough" tests.
2. I followed instructions given in this YouTube video: , and used msconfig to locate and uncheck the boxes for (1) WindowsErrorReporting and (2) ProblemsReportandSolutions. I also used this video's instructions to uninstall iCloud. The result of doing that is, possibly, a slow down in the blinking rate of icons within the taskbar and on the desktop, but the flashing continues. This was done during Windows normal mode (while icons were blinking); I have yet to attempt these same steps while in Windows Safe Mode.
3. I then followed instructions given in this YouTube video: , and used regedit to locate (1) ForegroundFlashCount and (2) ForegroundLockTimeout and reset each of those to 0 (zero). The result of doing that is no improvement/change in the flashing icons.
4. I also used Windows Restore to go back to 4 OCT 2018. That has not helped, either.

I think there was an automatic windows update done on my PC, overnight sometime after 5th OCT. I would like to know how to go about identifying and undoing the last Windows update? and how to disallow automatic updates from Microsoft?

I do not know what to do next. Any help would be appreciated.

TNX.

taskbar on multiple screens (XP)

Hi, at work we use three screens, with XP installed, on the PC i was using before it had the taskbar on just the left screen and when i maximised a window it would fill whatever screen the window was currently on. The pc i now use, has a task bar stretched across the three screens and when i maximise something it will automatically fill the left screen. Is there a way to change either of these things as i prefer the taskbar on the left screen and to maximise on the screen the window is in. Thanks
