SD card reader does not work under Windows 10

The problem happens with a Thinkpad R500 running 32-bit Windows 10.

The R500 has a built-in card reader, however, that reader no longer works properly.
Several times I've installed drivers for the card reader. Each time, the reader briefly works, then fails to operate the next time the R500 is used.
Checking the knowledge base and Levovo online support turns up no cause, explanation, or solution.
The card reader has been activated in the R500's BIOS.
SFC/scannow shows no problems.

Event viewer shows this:
Device SD\DISK&Generic&SD02G&8.0\6&1777445a&0&50324e24&0 could not be migrated.

I've card reader problems with my Dell laptop. The SD card disappears at random but reappears after a restart. I suspect its a driver problem but I've tried the latest Dell and Realtek drivers.

Hi, you reported this here:
Realtek Card Reader Keeps Disappearing - Page 2 - Windows 10 Forums

Maybe your driver has changed after you upgraded to the anniversary build? Maybe driver updates are no longer blocked?

Just after the AU, I noted the Realtek card reader driver installed was 10.0.14393.0 dated 15/7/16. I just looked after your post and it shows version 10.0.10240.21281 dated 2/10/15 which is the latest Dell version for my laptop. I've just run search for a better driver from Device Manager and it installed version 10.0.10125.21277 dated 10/8/15 which is the version W10 clean installed back in January. Go figure!

I would like to have version 10.0.14393.0 dated 15/7/16 which the AU installed recently but it doesn't want to update to this version.

The built in card reader is temperamental reagardless of driver. Maybe it's a hardware issue? I now use a Kingston USB SD card reader which is very reliable and fast.
