Questions and answers on a computer theme

Guys, tell me, I want to reinstall the operating system, but I would like to know first when my Windows was installed

Prompt please, through what time it is necessary to reinstall Windows, to me speak, that once a year it is necessary to do full reinstallation, whether so it?

Please tell me how often you need to clean your laptop and change the thermal paste. My neighbor does this every half a year, although I have not even once changed or done anything. Even I have no idea what it is, a laptop almost 2 years already. Is it necessary to do this?

Can you please tell me how to reduce the icons on the desktop in Windows 7. I installed a new OS, and the icons on the desktop are large, and the monitor is small. How can I reduce the size of icons?

Who can share the license key for Windows 10 ?. Can anyone give a key for Windows 10, it is free? The entire search rummaged, but never found a normal license. Activator for Windows 10 is not needed yet, I want to put just a normal license. If that, write in LS, even ready for a small fee (as they say on beer). Thank you in advance!

Please tell me why the computer can be droning. This morning turned on, but from so buzzing, never such a nebylo. Maybe the mind will soon come to an end, is it very critical? Thanks in advance for the answers. By the way, after 5 minutes of work everything disappears, and it works fine, such problems only when turned on.

The problem is, the USB controller driver flies after restarting Windows 7. The problem I'm thinking is in the operating system or drivers. Drivers put family, can that advise, as soon as I put the driver, all usb devices work, but it's worth turning off or rebooting the computer, again flying off, you need to put it again. What can be done and how to solve the problem. Maybe someone else faced such a problem? I did not try to reinstall Windows, but for me this is an extreme case, I want to solve the problem without reinstalling, if it turns out of course.

Tell me please, I click on the "Shut Down" button on the laptop, the laptop hangs and thinks, and the word "Shutdown" comes out but does not turn off, what can it be? Who can face such a problem. I have to turn off the button, but it's bad for the hard drive, what can I do? The driver has already updated everything, cleaned the program, but the problem remained.

Tell me what could be the matter, I bought a new laptop, but I can not install Windows 7, it gives out a blue screen. I was told that the new laptops do not already support Windows 7, in fact it is? I'm just used to Seven, I do not want to put Windows 8, I do not like it. How can this problem be solved? Laptop is new, Asus.

Friends, tell me please how you can connect the HP 1010 printer over the network. The problem with the driver, on the official site there are no drivers for Windows 7 X64. When connecting over the network, it gives an error and requires a driver, and is it possible to even put it on Windows 7 X64?
