So does windows XP Pro have to be activated like windows home, and how many computers can u install windows home vs. windows pro on?

and is there a limit to how much ram a 64bit operating system can use besides what your motherboard can handle. my mother board has a maximum of 16gigs.

Whats OEM? such as a windows OEM cd

Thanks
 
yes they all have to be activated except for OEM edition.
Theoretically one computer per software purchase, but if ya want to know a secret, **************, and you can install it in two computers.
Currently a 64 bit can use 6 GB, a 32bit can use 3GB, and if your board handles 16, there's no software in XP that can run it.
OEM is original equipment manufacturer
 


Full retail, upgrade, and OEM require activation. Volume license versions did not require activation.

The license terms for pro is the same as home.

There is a limit to how much ram a 64 bit OS can support. 16 terabytes I think. But no motherboard today comes close to it, nor will they for 10-15 years or so. Just as 4gb was way out of reach in 1990, so too is 16 terabytes today.

OEM is Original Equipment Manufacturer. As this pertains to windows, it is a license type intended for system builders.

 


Way off.

OEM DOES have to be activated. 64 bit is not limited to 6 GB. 32 bit use 4 GB, minus any hardware reserved memory.

Ok thanks guys. So if I wanted to upgrade windows xp 32bit to windows xp 64 bit would I have to buy another copy full retail or can I get a second licence. And if I installed windows on another computer would Microsoft know or do they not even keep track?

I have a lot of questions to be answered in the computer world xD

Thanks again for the quick responses :D

well if you reinstall windows OEM i'm pretty sure you will have to activate it. But if you just bought a computer with windows oem then it was pre activated in the factorie
 


You don't know what your talking about soundguruman. If it doesn't require activation than it has a hack, or isn't an OEM. ALL OEM copies require activation.

However, if you have a Royalty OEM machine like Dell or HP along with the factory disk, it would activate using SLP. This would appear transparent to the end user.

so what's the diference between a royalty oem and a normal oem? And what's SLP?
 


Depends on what is available these days for Windows XP 64 bit. Vista and 7 keys are interchangeable between 32 and 64 bit, but that was not the case with XP 32/64. So you would need a new license.

Better to buy Windows 7 if your buying new, unless you find a great deal on XP 64.
 


ALL OEM SOUNDGURUMAN!

Either its activating using SLP (which would appear to not need activation), it has a hack which is bypassing activation, or its a VLK that you THINK is OEM. It IS one of those 3.
 


^ -1 to all of this.

Additionally, unless you have a volume license, the end user isn't legally allowed to have the license on more than 1 PC at a time. Advocating this is tantamount to piracy.
 


Royalty OEM's are just the big OEMs like Acer, HP, and Dell among others.

SLP is system locked preinstallation. Its a combination of a bios table, an OS certificate, and a special OEM key that activates windows offline. This is why a big OEM windows disks or restore partitions do not appear to require activation. The SLP key and certificate is installed automatically. As long as the bios table is there, it will auto activate.

OEM disks you buy yourself have regular OEM keys that are subject to activation just like any retail edition of windows.
