I recently purchased a pre-built PC with windows 8 installed from a UK retailer. The PC did not come with a windows 8 installation cd, which I understand is not necessarily needed for preinstalled operating systems, but there is absolutely no sign of a COA sticker on the case or with any of the paperwork included. Are there any issues that could arise by me NOT having a COA? If I load up the PC it asks me to accept terms and conditions of windows and the supplier, which I'm reluctant to do without COA, but if I were to, I'd likely be able to get the product key from the system menu. With that product key and receipt of purchase, is that sufficient info to cover me for any possible 'issues' that may arise where I might need to prove that the license is owned by me?

Or should I insist that the supplier provide me with a COA? Newer laptops - look inside the battery compartment. COAs and/or product keys should never be purchased separately from the product. If you don’t see a Genuine Microsoft Label or COA, it’s likely that Windows isn’t properly licensed on that PC and may even be counterfeit software.

You are right the new pc's which are coming with the windows 8 are not having COA as well as the product key .the only option is to take the operating system backup to CD's (suppose your laptop is sony u can take back up with the help of ASSIT button it will ask for 3 DVD's ,if it is of LENOVO you can use one key recovery option same other brands provide with the help of fuction keys)if you want to reinstall it in future . I think Microsoft took this decision in order to make windows more secure and stopping piracy but the real question is that what if suppose the CD's get damaged . earlier CD's or Key is used to reinstall the os on the same machine if one is lost the other can be used but with windows 8 we have the only one option to get back our original OS that is OS Back up into CD's. Thanks for your feedback, it helps us improve the site. Microsoft introduced product activation with the release of Windows XP. Over the years Microsoft has refined the experience. Windows 8 takes it a step further, in fact, product activation is invisible. When you setup Windows 8 on a new computer, you have to initially enter the product key (unlike Windows 7 which required this during the Out of Box Experience). The minute Windows 8 detects an Internet Connection it activates itself. Windows 8 does not have the old 30 day grace period familiar to Windows Vista and Windows 7 users. You can continue to run Windows 8 including Metro applications without any hindrance, you just won’t be able to access certain customization options such as the ability to change your Start Screen background, start screen and color scheme. A watermark will also become apparent on screen and cannot be hidden, it even appears on your programs, so if you watching a full screen movie, you will see a watermark. Activation still supports tradition phone activation, so if you are nowhere near an Internet activation, you should not have to worry. Managing your genuine status in Windows 8 is also much easier. You can view your partial product key (something that required command line operations in previous versions of Windows), so if you have multiple copies of Windows 8 installed on different PC’s throughout your home, you can match and compare. If you need to purchase an additional license, you can also do some from the new Genuine Center in Windows 8. One of the improvements Microsoft is making to Activation 3.0 for newly built machines that come preloaded with Windows 8, you won’t have a COA (Certificate of Authenticity) sticker attached to the machine anymore. This will avoid product keys from being compromised and OEMs will buy what they need. Thanks for your feedback, it helps us improve the site. Hi Andre Da Costa, That's Great with the New Activation 3.0 technology I too heard that with Activation 3.0 Security concerns are more and Genunity is maintained at higher levels but I have some doubts regarding the Activation 3.0. 1)If customer bought a new laptop with preloaded windows 8 (without COA) and used that for some particular period of time after that suppose his OS gets crashed and he lost his backup CD's also .what is the solution for him ,how he can get back his OS? 2)the customer upgraded to windows 8 after some days unexpectedly his OS got crashed and he wants to reinstall windows 8 directly by running windows 8 setup and entering the product key which he got at the time of upgradation can he get back his windows 8 back by doing so or he need to install windows 7 first then upgrade to windows 8 ? what would be the solution for this kind of problem? 3) how we can see the product key which is embedded in BIOS?

If CD's get damaged, contact the computer manufacturer for replacement cds if they are still available for Windows OS. An OEM can provide media that can restore a computer to its original factory software configuration. Disk Cloning - Scroll down to How It Works section.

Thanks for your feedback, it helps us improve the site. my doubt is earlier with windows 7 either the key or the CD's are used if one lost we can make use of the other but with windows 8 key is not provided and we need to totally depend on CD's ,that is not a good scenario and more over I heard the PC manufacturers will provide only one set of replacement CD's(either in damaged or lost situation) .what if we lose that also??

when going back to windows 7 scenario we can download the setup and enter our key by this the process is easy to get back our OS without waiting for CD's. is there any kind of process with windows 8 also please suggest me regarding this and clarify my second and third point also which I ve mentioned in the above post.

You have a couple options: If you would like to reinstall Windows 8, which means removing apps and personal files and settings, you can use reset and refresh.
