(1) If your vision problem is cataracts, try Ctrl+WinKey+C. It will toggle Color Filters on/off. Mine is set simply to "Inverted" at "START, Settings, Ease of Access, Color Filters". It makes a big difference
to see white type on black instead of vice versa. Unfortunately, pictures & videos are also inverted. But it's easy enough to just toggle it back when necessary.
(2) I heard tales of the deprecation of Windows Backup & Restore from back in Win 8.1. But it is still here a ton of versions later in 20H2. I believe the deprecation came & went with Win 8. My Win 8.1 had it, & everyone got it back with Win 10. I will sorely
miss it, if indeed it will go again.
(3) You can retrieve individual files/folders from a Windows image two ways w/o having to restore the entire image. Here is my write-up...
(a) To backup the entire computer, make a Windows system image backup. It makes a backup of all the Windows partitions required to boot & run Windows: EFI, MSR, Windows (C:), & Recovery.
If you've got additional partition(s), they will also be offered for inclusion. (OK, some very well hidden partitions, like a manufacturer factory reinstall partition, will not be offered to backup). A 2 TB external HDD is large enough to never fill with images.
An 8 GB flash drive should be large enough to hold a Recovery drive (used to restore an image).
I make one after each new OS Build comes in & runs well, & I keep the last three...

I rename the computername folder which is inside the WindowsImageBackup folder (by appending the OS Build to it) in order to keep them separate & distinct. All three will be offered during the restore process.
Make it at "START, Settings, Update & Security, Backup, Go to backup & Restore (Win 7), Create a system image". Afterward, make the Repair Disc or (even better) ask Cortana for Recovery Drive to put it on USB. That
can be used to do a restore. Then see the following to know how to restore one...

How to restore a Windows 10 system image to an existing or larger storage device

Restore a System Image Backup in Windows 7, 8, 8.1 and 10
Note: That is an informative 3rd-party site, but I know nothing (good or bad) about any downloads or links that are there (or anywhere else).
If your external hard drive (or the internal one I guess) is a Seagate or Maxtor, there will be a free version of Acronis True Image at their site. Seagate calls it DiscWizard. Macrium Reflect, AOMEI Backupper & others also offer free versions of their image
makers. These 3rd-party apps are quicker, make more compact images, & are more flexible in use. But the Windows version works in under 15 minutes on my small & uncomplicated system. I must add, DiscWizard's Bootable Media (to restore an image when Windows
won't boot) requires a Mouse to operate. Plug one in, & it is instantly recognized.
(b) The Windows partition (C:) that is in the image can be mounted & individual files copied off it. I did that once to recover just my Downloads folder which I had inadvertently wiped. To do so, double-click the largest .vhdx in
the backup folder in File Explorer...

That will be the image of the C: partition. It will get a letter (say, E:) & open in a 2nd instance of File Explorer. You may put it side by side with the 1st instance. Then browse to your files & copy them from E: to C:. (But I wouldn't try the reverse.)
When done, right-click E:, & select "Eject".
[But I must add, the first time you double-click a .vhdx, it may give an error message. So, just OK the error, & open Disk Management. The mounted image will have the same name C: has, but no letter. Put a letter on it, & it will show up in File Explorer.]
(c) You actually don't even have to mount the image to recover files off it. And the external HDD that holds the image doesn't even need to be plugged in. A shadow copy is made to some secret area on the internal HDD each time an
image is made. They can be accessed in File Explorer. Just right-click C:, & select "Restore previous versions". Then select the image you want by date, & click "Open". A 2nd instance of
File Explorer (the 1st instance is behind it) opens with C: the way it was when the image was made. You may now copy individual files & folders. When done, just close the 2nd instance. (I haven't dared try copying files ontothe image. I just copy
them off.)
