Windows 10: Windows 10 Pro: what does this cryptic pop-up message mean?

I've been using Windows 10 Home since it was first released. I've just recently purchased my first Windows 10 Pro PC and set it up using bitlocker for the internal drive. In general the new PC works fine but from time to time it suddenly pops up a strange looking warning which seems to relate to some issue on the internal or external, if one is connected disk see image below. I have never seen anything like it on my Windows 10 Home PCs. I have no idea what the strange message means and what I need to do to resolve the issue. The pop-up will cover the screen and prevents me continuing with what I am doing until I make it disappear by pressingConfirm. Then, at some time later, a similar pop up will appear and the pantomime is repeated. I haven't a clue how it expects me to deal with the matter so as to avoid similar popup messages appearing at random times in the future.

Is there a way to see a history of the messages that pop up in the bottom right of Windows 10?

I'm trying to overclock at the moment and twice now while in the middle of a Prime 95 test, a message popped up in the bottom right but was only there for half a second or so. It was gone so fast that I couldn't even read any of the message, but I saw it was red with the X meaning bad mojo.

I thought to check event viewer but I don't see anything there. What could the message be? For what it's worth the overclock seems stable. This is a fresh installation of Windows 10 64-bit.

 

Windows 10 Backup Cryptic Message

"Windows 10 Inside Out 2nd Edition" book says that you can only use an external hard drive or network for backing up files. My HP support page says that I can use a flash drive. I'm using a USB flash drive but I keep getting the cryptic message: "Select
a Different File History Drive: File History can't save copies of all of your files because of limitations with your file history drive's file system. We recommend you select a different drive."

What does that message mean exactly and how can I determine what files were actually backed up on my USB flash drive?

 

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK
