What is the best way to organize a computer for different needs?

Question

Windows

Hello everyone! At home there is a PC running Win 7. I did not install any other OS. On this computer, I have fun (games, movies, the Internet) and work (coding in C #). In connection with the expansion of working tools (Unity 3D, UE, etc.), a question arose. Which is better: put another Win 7 side by side (fortunately, there is no allocated space) or create an additional account in the current Win 7 in which there will be no games or other crap?
In this question, I have sub questions.
Case 1: Now I don't have any custom loaders installed. Will I have problems starting the systems? I have never seen a PC with two Win OSes. The standard bootloader will allow you to choose which OS to run?
Case 2: Is it possible to create an account from scratch? So that programs and services in the main account are not available (and in general there is no trace of them) in the new account?

Answer 1

1. When you install programs, you probably notice sometimes the checkboxes "Make the program available to all users" or something like that? So the second user will not solve the problem, too much "common" good is worth it. Even if the mentioned daws are removed, which practically no one ever does)
2. Parallel OS will create difficulties (great need for space on the HDD, switching time, longer loading due to the choice of OS).
3. A parallel "relatively clean" OS will not improve PC performance much.
As practice shows, improving PC performance is easiest - and most reliable - by assembling a normal PC. The "shit" you mentioned does not slow down the system as much as it seems at first glance (if, of course, not everything is running, in the style of "antivirus on antivirus and agent.mail.ru drives").

Sometimes it's more correct to allocate the same budget, collect something decent with an SSD, 16GB of memory, and a core i5. Then you will get a lot of free time due to the lack of brakes and spending it on thinking (and creating) unnecessary, unnecessary entities that will not give a result worthy of the time spent on this. And you still won’t have enough resources, if not immediately, then in a month or two (in fact, right away).
My experience shows that a good, high-quality, expensive (which does not necessarily mean "expensive") tool is not only more pleasant to work with, but also more efficient. It doesn't matter what area.

Answer 2

I think it will be practical to go from simple to complex:
1. First, create a new account and try to work like this. If you do not like it, then
2. Put the second OS. I've put myself on a laptop 7 and 8 - they work fine. It takes a really long time to switch between them. But in terms of the use of RAM - a good option. If it sucks, then
3. Buy a new computer more powerful.

Answer 3

hmm. don't listen to their dad. This is the age of virtualization. roll hyper-vi and divide roles into virtual machines.
