Missing text after reboot in Win 10 Pro 64bit CU

Norton NIS did its normal update the other day and, as sometimes requested, it asked for a reboot. Now, I've been using Norton NIS for 17 years and there's been no problem with it and Windows so this cause for a reboot shouldn't be an issue but.........

after I rebooted, the desktop, all folders, all menus, etc., came up missing descriptive text, just icons. I'd include a screenshot of this using Paint but using 'Print screen' or 'alt print screen' and trying to 'paste' it into Paint produces a blank picture. Beside, all the selections in Paint are icon only and even if you hover over the icon, no description comes up.

Anyway, I rebooted again to the same issue. I finally had to use Macrim to restore an image from a few days ago as the Win 10 CU rescue disk could not 'repair' the problems.

I'm sure this is a CU problem, not Norton. Has anyone heard of this happening to a Win OS?

Also, how do you boot to Safe Mode in Win 10? I know that sometimes you have to use the rescue disk for this but the rescue disk for CU did not have the Startup Settings under Advanced options.

Thanks.

Thanks. But those options depend on having text available or a 'repair' disk that has Safe Mode in the Advanced selection (which my CU repair disk, unfortunately, does not have). And using the Command Prompt when you don't have text doesn't work because you don't have any (eg. C:\) visible and you can't see what you type).

Too bad there isn't a 'F' key option on boot, like XP used to have.

As an aside, I tried your 'Add Safe Mode to Boot Options' using MSCONFIG. Will let you know if this works when I reboot later this afternoon.

Thanks.

Thanks.

F8 might work on my system because my mobo has a 15 second 'go to bios' screen before actually starting Windows. I'll give it a try.

Thanks again.
