SanDisk microSD memory card is write protected or locked

I got this issue with a brand new 32GB SanDisk Ultra microSD Class 10 when trying to copy data with my laptop:

"The disk is write-protected"

It took me about 20 minutes to find out why.

I could save images to the the microSD when inserting it directly to my smartphone (without the microSD adapter.

The root cause: The lock switch on the adapter is loose, it may slide to Lock position when I insert it to my laptop's SD slot.

Hope this sharing can save you time!

Docker for Windows: Access Denied

Today, I get this error when running Docker for Windows on Windows 10 Build 1803. So, I check my current username (run whoami ) and add that user to docker-users local group, which has only NT AUTHORITY\SYSTEM account in members list. I must log out and log in again to run Docker for Windows.
