Windows Recovery Environment explained

This is very confusing to me as I am Technologically Ill . All I know is every "quality upgrade and fix" creates more down time and hours of digging for answers to fix the things that either no longer work or that happened after the update(s). I have currently been researching for over 2 hours on how to do a clean install of windows 10. I save a screenshot of all the directions to be able to follow each step in order and have so far made it to the part that says I'll need the license key . My laptop is new and up to date with all current windows up dates.I have changed nor added anything and after the update(s) now it takes several years to open Firefox and several more for it to visualize or be visible to utilize and then is slower than my dead Grandmother getting there and now file explorer is just as bad. No matter where I go such as downloads or documents the green line of never ending progress never stops progressing and my files take 5-10 or more minutes to show the thumbnail to choose from. I have a 1TB HDD with 397mb's available nothing changed but the updates and all these issues. I realize this is long and drawn out and not even your problem . Your just the unlucky one I found when the straw that broke the camel's back was added to my camel. The thing is that caused all this 4 month message is I typed a simple question in the search box in my Microsoft account"Where is my bitlocker recovery key located and how to access it" and honestly no matter what question anyone asks, I never get a simple answer that my simple mind is capable of computing. I get more rocket science to confuse me further and waste more valuable time and usually some unlucky tech genius gets to read my rant. I'm going to ask one more question and if it cannot be answered in simple terms please call 911 and tell them that a mentally ill man needs help, you have my email address and we all the government knows who and where???  Question: Why does one simple question lead to a link that supposedly will answer the question, lead to no answer and more miles and miles of reading only to find out I still don't know where my key is so I can continue following whatever the next part of the instructions Microsoft tells me to follow to hopefully (I'm praying to God) fix what the "Quality update and fixes" did to cause all this. And now a new pop up  telling me something I haven't got a clue  about"Your content was last saved to auto recover at 02:49PM. Please save your document, using the save button, regularly to avoid data loss." Okay Microsoft has officially driven me insane, what the Hades is this about and I don't have a save button. I give up just have the guys in white suits come get me and give me a padded room and a life time supply of Thorazine

. And to think I made the presidents list my first year of college in 2012 and was invited 3 times to join Phi Theta Kappa honors society at Texas A&M university the following 3 years. Happy Thanksgiving and have a wonderful day I sincerely mean that I'm just fed up with all the hours and hours of wasted time trying to get back to operating condition from Microsoft's errors and time is one thing that cannot be replaced or purchased.
