I have to enter 48-digit Bit Locker recovery key every time I boot

Using Windows 10 on a Dell laptop for about a year.  All of a sudden, every time I boot up, it asks for a Bit Locker recovery key, and I have to enter 48 f'n digits!  I had never heard of Bit Locker, and to my knowledge I have never turned it on or off.  Per a You Tube video, I have disabled Bit Locker, but I still get the prompt and have to enter all 48 digits again.

I'm a single user and have little need for sophisticated security.  How can I get rid of this stupid prompt?

Where did you get the key?
Did someone give you a secure thumbdrive maybe?
Bitlocker is baked into Win10pro/enterprise. It can't b e"uninstalled". Open the control panel and double click bitlocker then look for the  the drive that shows bitlocker is on and turn it off.

If you have the 48-digit key, you can decrypt the machine anytime you like and you'll never be asked again.Right click c:, select manage bitlocker and select "turn off bitlocker".

It seems you did something else in order to turn it off.

Thanks!  McKnife's, and maybe others did the trick.

I had previously tried:

Control panel
Admin tools
BL drive encryption

Not sure what that accomplished.

That did the trick - Thanks!

I had previously gone to:  Control panel; category; admin tools; services; BL drive encryption; properties; Start-up; disable.

So I'm not sure what that was to accomplish.

Thanks again!
Fine. Without BL, anyone with physical access to your machine is able to manipulate it (and access all data) - I hope you are Aware of that.
