How many computers can I install Windows Vista with only 1 disc?

I have 2 computers, but I only want to buy one Vista CD. So, can I install it to both of my computers with CD? Is it legal?

Probably won't fly. I know you speak of Windows Vista, but I assume it will work like XP and probably moreso. Let me quote from the WindowsXP Gigabook, by Peter Weverka.

"Windows installer makes you type the unique 25-character code that's printed on the case of your Windows XP CD. Later, the Product Activation programs looks at various serial numbers inside your PC - the processor, network card, and disk drives, etc. -- mixes them together, and produces a second 25-character code that identifies your PC. Those 50 characters, taken together, are called the installation ID.

When you activate Windows XP, you give Microsoft the 50 character installation ID.

I'm going to skip some information here -- to continue -- every time WindowsXP starts, it recalculates the 25-character code that's based on the various serial numbers inside your PC. If the recalculated 25-character code doesn't match your original code, the activation time clock starts over and it continues to remind you relentlessly, etc. etc.

All this and much more is covered in Chapter 2.

I bought this $35 book for $3.50 and shipping at www.amazon.com as a used book.
