Small shops ... they struggle.
Medium shops re-image your profile after every use. You store your docs on a central server but each time you log in, you got a fresh profile. The user is less productive but they can't screw up. Really, it deletes everything every time you log out.
Big shops push the changes out to you. You can't delete an icon off your desktop if they don't allow it. You can't patch them yourself. You suffer a little productivity loss but again, you can't screw it up.
In the end, if you do what they recommend it works. Back-up your files to external server or jump drive. Really, do that ... costs almost nothing and you can restore your files to almost any point in time. If you don't trust the services, buy a cheap external drive.
Don't click on a link in an email until you've counted to 5 "Bill Gates is a Pedo"'s. Really, no one is sending you something you have to click. Not your bank, not the IRS, not your Mom, or brother. Pause and look at it. Really they aren't. You know who is? People that are trying to screw with you.
If you are smart, you won't run in admin mode. Create a separate profile on your machine to install software. And, run in the one that can't. It's nuisance but ... you can't kill yourself if you don't have that ability. (I'm not smart either but I haven't had a problem.) It takes 3 minutes and you will be glad you did it when you click on a bad link.
Keep your windows discs. If they didn't send you some, order them or make them from the windows installation. With your backup above and the windows discs you can restore your machine. A few hours in and you are back to business. Does your car battery die? Does your phone run out of power? Why wouldn't your computer?
And lastly, if you have a problem, whatever your first thought is ... immediately assume that is wrong. Pause, and look at what you really know and then solve the problem. Jumping to a conclusion is 98% of the time wrong. It's hard to not do that but you will have less stress. This really is the most useful thing I've learned in 45 years on computers. The first thing you think of is, is almost always wrong. If you don't discipline yourself, you'll never move off it.
