Pros: Very fast system, data transfer is faster than 32 bit, OEM but you can still upgrade any part and that includes motherboard just need to call microsoft to the number they give you and tell them and they wil reactivate it for you, alot of eye candy that actually works, Makes XP look bad and works ALOT better

Cons: Cant make a system image for hard drive failure but thats why you get pro or ulitimate.

Overall Review: To the person that keeps saying you cant upgrade motherboards he needs to learn that you can. call the 1-800 number they give you and they will reactivate it for you. I am on my second mb now using this as i went from am2+ to an am3 mb took a whole 5 minutes to call and get a new number wasnt even on hold.

Pros: THIS is what Vista should have been. I am running W7x64 and loving it. This is the first time I've gone to a 64-Bit OS, have been too hesitant previously. The OS is very slick & very fast on moderate hardware. I am running an Intel i3-530 on 4GB RAM an using the on-cpu video at the moment. This scores me a 4.9 on the rating, due to on-board CPU video. I have not installed any games yet, waiting until I get my new video card, but all of my other pre-existing software is working & fully functional: Adobe Photoshop Elements 7 Boilsoft Graboid Office 2003 anyDVD cloneDVD Videora Even older hardware that I could not find W7 drivers for (let alone x64 versions) is also working fine, most notably my tiny Sony DPP-FP30 photo printer.

Cons: um... maybe they should give an extra discount to people with a valid Vista license?

Overall Review: I have been building my own systems for 15 years now, and have always purchased the OEM version of Windows & have this time as well. You can change any of the hardware you want to, it does not matter. If too much hardware changes or you need to swap out the Mobo, it will require you to re-activate the license. This is no big deal as long as you call the number and TELL THEM THE OLD HARDWARE DIED. Do NOT say you upgraded, as this will then leave the decision up to that particular rep as to whether or not to re-activate you. A hardware failure & replacement REQUIRES them to renew your license & activate it for you.

Pros: Great OS.

Cons: N/A

Overall Review: This review is just to clarify for people who are uncertain. You can buy this OEM version of Win7 and install it on your new build with no problems or hassle. There is a lot of MS legalese written all over this product which is meant to discourage casual users from buying it. The primary difference between this OEM version and your retail version is that you cannot easily transfer this OS from one computer to another. If you buy this version, it will install, activate and run just like the retail version. The OPK kit which is mentioned by MS is NOT required; this is only needed if you intend to resell the computer as brand new after you have installed and configured Windows. There really is no reason for the average builder to pay for the retail version.

Pros: Windows 7 is a highly stable, high performance operating system. IMHO, Windows 7 Home Premium (x64) is the best option for the home user or gamer. This version of Windows is what I use on all customer builds that do not require the added functionality you get with Windows 7 Professional or Ultimate. There is no performance difference between versions, only different enabled functionality.

Cons: Windows 7 Home Premium x64 gets the job done, however there are drawbacks for anybody that has a large heavily-used home/business network. You cannot host Remote Desktop sessions with Home Premium. If you require Remote Desktop, one must use Windows 7 Professional Edition. You do not get EFS (Encrypted File System) functionality with Home Premium. No XP mode (which 99% of users will never need/use anyhow). Cannot join a domain (not really a requirement for most situations, but for businesses or people using the computer in a networked environment, domain join may be a requirement that Home Premium will not meet. Use Windows 7 Professional Edition if you need Domain Join functionality.)

Overall Review: Many will argue about the best, most stable, most functional version of Windows. Many die-hards will argue Windows XP vs Windows 7, claiming Windows XP is the best there is. In my opinion, Windows 7 far surpasses the end-user quality of use, functionality, ergonomics, and performance that of Windows XP. I do not believe Vista is even worth mentioning. Windows 7 has the same basic interface and GUI as Windows Vista, but is far superior by design. It is WELL worth the money upgrading from Windows Vista to Windows 7. The same applies for Windows XP. Many will argue that Windows 7 is a memory hog. That is true, and that is a good thing - RAM is faster than a hard drive, and by todays standards, your computer should have plenty of RAM. 2GB of RAM is plenty to run Windows 7. The more the merrier, but whatever amount of RAM you have - Windows 7 will utilize it in the best ways possible to give you the best performance from your system. IMHO, Windows 7 is the best Windows versi

Pros: Windows 7 works great. Make sure you buy the 64 bit version if you ever want to see more than 4G of RAM. $99 is not cheap, but better than $179.99 for the retail version. Buy OEM, not the retail version. Unless you feel you have too much money.

Cons: I wish it was less expensive.

Overall Review: I wish it allowed you to backup to another hard-drive on your network and allowed for remote desktop, but those are not features of Home Premium.

Pros: Beats the socks off Vista. Duh! Slick interface. FAST install. Took me 24 minutes from the moment I threw the DVD into the DVD drive to final user account login - and only two auto-reboots. Not too shabby. Found all hardware, setup the local network, etc. Idiot-proof.

Cons: Before...the 'con' could be that its a Microsoft product, ergo we had no choice. But not anymore...heh. Takes some getting used too since MS...in their infinite wisdom...decided to move and/or rename certain functions. Oh well...keeps one entertained...

Overall Review: Should have gotten it sooner...

Pros: works great right out of the box. no instalation problems. Great price. Runs faster than vista, and doesn't seem to bog down my system like vista did. Love the fact that it is 64 bit and I can use more than 3 gig of ram. Hopefully with this release Microsoft finally got it right.

Cons: it doesn't make sausage egg and cheese burritios

Overall Review: If you have older hardware make sure you check with your manufacturer to see if they have windows 7 drivers, especially if you have older hardware

Pros: $104 for the newest windows OS W7 is ba for sure

Cons: It costs $104 It's OEM My CD was a little scratched from rubbing against the w7 booklet inside. It took a full 7 days to get here (ordered on monday, got here next monday, the day w7 beta "expired")

Overall Review: The W7 disc comes in a clear dvd case with the product key right on the outside and the case is safely tucked away in a cardboard protector thing.
