shops putting os on systems

[scrappydooo]

how can a shop format your hdd and put on a new os? do they put on new ones and you pay for the whole thing or do they have copies with special product codes?

Okay, you know what? This is your third ridiculous post. You want to go into the computer repair business but you barely know how to turn on a computer. You need to buy a book.

Yes, get a book. Read it.
How to Start and Run Your Own Computer Repair Business

is that not what the forums for?

Yes, and from time to time we give homework assignments.

It's for helping people fix their computers and ask questions.

The questions you ask bear the mark of Did not do the research (tm).

There are two kinds of Repair shops:

The shady ones that just throw pirated copies of windows on every machine.

The legit ones that actually have a system builders license and will install a legit copy of windows on the machine using the product key on it. There is also a third type, which basically just installs whatever Linux distro they think is cool, gives the person a link to a help forum and let's them deal with it. Because the best way to get people to switch from windows is to force them, I guess.

The link I gave him is for a real book sold in real book stores for under $20. He should buy it and read it. That is much, much faster than sating online and asking question with no structure. Most people can not type much more that 40 words per min. An average reader can read 300 words per min. And with good comprehension from a well-prepare textbook.
This is not to discourage the OP, rather to encourage him to make the best use of his resources. A computer is spoor resource if you do not have any idea of what you  are looking for. Some independent research and study away from then keyboard is needed to get the big picture of things. The OP may find thee is a better future in writing books instead of repairing computers.
Of he can not afford a book, he can go to the library.
