You would be unable to boot or use your computer until you reinstalled an operating system. You would lose any personal data you had saved on your computer.
Yes. When my sister plays it, my computer thinks im always holding the "ctrl" key. so pressing "P" alone would open the print window and "T" would open a new tab etc.
I think so!
I have uninstalled/reinstalled in around 4 times. I have had no complications due to Warcraft 3, so I would say "No".
No it does not have a virus.I have an account and it is completely safe.If it did my computer would have crashed by now
If you don't have an up-to date computer, your account will still be valid, but you can not play on that computer. All you have to do is get a new computer and re-download Minecraft, then sign in as you usually would.
With out one, the computer would not know what to do. You would not be able to interact with the hardware that makes up a computer. Picture it this way... Without an operating system the computer would be as lost as a someone who is stuck on island that crashed there via plane and has no recollection of how they even got on a plane or how long ago they crashed, with no GPS, phone, or contact with anyone or anything outside his little bubble of existence.
No you can't, there would be a lot of compatability problems.
I would suggest making your own computer. It can be a little expensive but its definitely worth the time and the money. If you don't know how to build a computer there are many great tutorials online that can show you.
Minecraft works on almost any computer from the last 10 years or so, unless the computer doesn't have enough memory space left.
it would work but it would be very VERY slow for the other computer
You could try running minecraft through a torrent, and getting an aggressive internet security system. However, your best bet would be to do the legal thing, and pay for your minecraft.
