The Same way you installed it on the First one. Microsoft will let you activate the same key a few times before it blocks it as they really don't want you to use the same Key on multiple boxes. They lose money this way. I don't see a problem doing it to 2 home PC's. just don't go giveing your Key to friends. Or go using it to load XP on 30 company machines. That's a bad thing.
If you already have a version of windows installed, you could try upgrading from the version you already have installed, but that isn't really installing windows freshly. You'd need to reconfigure your BIOS to boot from the CD. Try checking the manual from your bios or motherboard manufacturer on how to do this, or read the documentation that came with your computer.
To function as a server a computer must be running as a WINDOWS based server i.e windows 2000, windows NT, windows 2k3, windows 2k8 editions of server installed on computer the server could be Linux based as well.
You could put the installation file on the external HDD to install it on another computer but then to install it, it would have to be on a local HDD.
those are operating systems, not programs. you could have both installed and have a dual boot set up to run one or the other. or you could install a program such as Virtual PC so that you can run one in virtual memory while the other is loaded.
Answer You can install the same copy of Windows on more than one computer, but the other installations won't be considered legal. Maybe you could use a router so that the information on one computer is automatically sent to a second computer and that way you aren't breaking any laws.
No. Windows XP is an operating system. Microsoft Excel is an application. It must be purchased separately. When you buy a computer you could ask to buy a version of Microsoft Office and have it installed on your computer, but it does not come automatically with your computer.
You don't download MS Paint, so you must have gotten another program. Whatever you installed could not have been installed completely, or it could have put a virus on your computer. Another possible reason is the more programs you install or download, the more slow your computer becomes.
Virtualbox is a program that you can install and will enable you to install another operating system on your computer. It will share the ram and CPU power of your other OS. For example if you are running Linux and install virtualbox you can then install windows (any version) and run it as if it were a windows computer, You could install and run any windows software. This is one example of using a virtual machine. At this link you can download the program and find the documentation and some screenshots, etc. http://www.virtualbox.org
Windows 8 refers to the operating system (OS) on a computer, and if you had, for example, a computer with Windows7 and you wanted it to be 8, you could just purchase a copy of Windows 8, put the installation disk into your computer and follow the instructions to install windows 8.
It depends on what you are trying to do. If you install anything over Windows 7 that is not a windows based system you may lose some application functionality if the other system does not have an equivalent. The same could be said if installing Ubuntu, since it may have functionality that is not present in Windows 7.
You need either to install packet.dll or if it's already installed you have to register it in the windows registry.
You cannot imagine how great it would be if Seven could do that. In order to install you have to burn that image on DVD and boot from that DVD (or start installation Windows if the image which you have supports such mode, not all of them do).
