windows xp pro requirements The minimum hardware requirements for Windows XP Professional include: .Pentium 233-megahertz (MHz) processor or faster (300 MHz is recommended) .At least 64 megabytes (MB) of RAM (128 MB is recommended) .At least 1.5 gigabytes (GB) of available space on the hard disk .CD-ROM or DVD-ROM drive .Keyboard and a Microsoft Mouse or some other compatible pointing device .Video adapter and monitor with Super VGA (800 x 600) or higher resolution .Sound card .Speakers or headphones

windows 7 requirements .1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor

.1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)

.16 GB available hard disk space (32-bit) or 20 GB (64-bit)

.DirectX 9 graphics device with WDDM 1.0 or higher driver from microsoft a very big difference and the size is really big,hard to fit in a flash drive for small robot designs to use as a hard drive

then why would very big companies buy a software that you cant buy any more and put in thier systems and had to get support for it too they are still selling windows xp too,just cant buy from microsoft i never asked for support for windows xp or never will need it and same with my windows 7 i dont need any support too also someone bought up of a power drain issue ,my windows 7 i did the test has all the lastest patches as windows xp

looking at not to make any more comments on this thread sorry but that how i feel i need to start building robots more

@Robotmaker

I have already answered your question about why some companies will buy Windows 7 licenses and exercise their downgrade rights to XP. That is currently only available to OEMs and corporate customers, not individuals anymore.

You can buy ANYTHING, or even find most OS or software for free somewhere. Those licenses are not legal. Microsoft owns the software and licenses its use. No one is legally allowed to sell it without a reseller agreement, and if they are selling it now (other than as an OEM or embedded system as mentioned above), they are violating that agreement. Doesn't mean you can't find it, but I am not going to recommend stealing software or buying from thieves on a hardware/software company's support forum.

The support that everyone needs from Microsoft is security patches. Unless you are a corporate customer or OEM, you can't get them for XP, and even then, you need to pay for them since 2009. Without those patches, your XP install is vulnerable to malware. Again, I would never recommend someone use an operating system that can't receive security patches. If you never connect your XP powered robot to the internet or a network with other computers, then security patching may not be an issue for you, but many of us want to be able to remotely access our robot's via the internet, so it is an issue for us.

ones i buy does have a license,i dont buy bootleg copies of anything on malware you dont need a patch,norton and others can get rid of it iits been a over a year since i need a patch and they send me some and i do not install them i never found that i ever needed a patch on my systems and i use remote access alot since i travel alot and want to see whats going on at my house,with my camera's and alarm system design and i can control any lights or anything else from any country in the world also so far i never got a virus after i made a changes to my computer and router and if i did get one i found a super fast fast to get rid of it i make a backup hard drive thats clean,any files i save goes straight to a flash drive and remove it after the download if left on the computer ia virus might get on it

second i remove the drive and put in new drive,and i dont have to open my computer so i really dont need a virus protection it does slow the computer down

also same reason i never need security patches,may be others do

It's obvious from what I've just read that @Robotmaker thinks he knows more than he actually does or has been told a lot of poor ways to carry out tasks that just should not be done that way. That's not meant in a bad way by any means. It's just some of the things you have said are untrue or not good practice... In fact it's very bad practice... If you don't have virus protection how do you know the backup of the hard drive is clean?

@thetechguru I resell Microsoft licences, as far as I know authorisation is not required but perhaps that is just in the UK or maybe I missed that bit... I will have to check that out.

RICH you are wrong ,why you dont know me at all ,so please dont say i was told a poor ways to carry out tasks,you have you ways that work and i have mine the does work for me on the backup it started as a clean drive a long time ago and when you copy a drive it doesnt get any virus i have one computer with no internet at all,so no virus can get on it ,that why YOU DONT KNOW ME mad mad starting to get nmad and i have never ever done it

also there in windows xp a program that checks to see if you have a license for it or installed in another computer and wont work after a awhile also OEM i think doesnt have it and most will only work on certain cumputers ,like a OEM FOR DELL will only work on dell machines

@Robotmaker

Rich was not insulting you. He is informing you that if you are not taking Microsoft patches, and just relying on anti-virus, and worse, if you aren't even running Anti-virus and also not taking patches, you are not following the most basic computer security best practices. You are very lucky if you have never had a virus. Maybe the poor performance on your Windows 7 was because you got a virus you don't even know about. Certainly, if you don't take patches, then you could have the poor battery performance bug. Patches aren't just for vulnerabilities, just 90% of them are....

If you don't follow the most basic practices of protecting your software, you may want to stick to hardware advice (of which much of yours is very good) and leave operating system advice to experts like Rich.
