BIT LOCKER RECOVERY

Greetings everyone,

Recently Microsoft Windows forced into entering an update upon closing my laptop. After that I could not boot up without being asked to enter a Bit Locker Recovery key.I eventually found the correct key and entered it this morning successfully.Laptop was up and running ok or so I thought.Switched the laptop on just now and low and behold I have to put the Recovery key in again.!!I gather the problem arrived during the last update.I s there a fix for this or am I now having to put the key in every single time I switch the laptop on!! Is it possible to remove the faulty update? 

Many thanks for any help received
