1: Overview of Product Keys for Windows 10 Professional, 64 Bit
2: Legitimate Sources for Obtaining Product Keys 
One of the most legitimate sources when it comes to purchasing valid product keys would be online stores like Amazon or eBay. Here you can buy genuine codes at reasonable prices directly from the manufacturer. In addition, they also offer customer support if there are any issues with your purchase should something go wrong during the process. You might even be able to get discounts if your purchase qualifies as part of a bundle package deal so keep an eye out! Another way of getting product keys is through software developers’ websites who usually have promotional campaigns every now and then offering free trials or discounted rates depending on their marketing strategy at that time – do take advantage of those deals if you can! Finally, Microsoft also offers their own official store where they sell licenses for their products at full prices. However, it is usually a good idea to shop around first as other retailers may offer better deals that are lower than what’s being offered by the manufacturer itself. 3: Pirate Sources and Free Keys
Unfortunately, not everyone has the means to purchase genuine product keys or pay for subscriptions or trials. In this case, some users may resort to acquiring pirate sources with questionable validity such as torrent websites – which should be done at your own risk since these codes might be invalid or already used before by another user when trying to activate Windows 10 on a new device.
In addition there have been reports of hackers creating tools specifically designed in order to generate valid product keys without having any direct access from outside parties – take caution here too when using them since such methods rarely last long due to rapid changes made by Microsoft towards improving security measures against piracy attempts from occurring within its system; one wrong move and you could end up facing an unverified key situation rather than benefiting from it instead!
4: Conclusion
When it comes down finding product keys for Windows 10 Professional 64-bit versions of the OS, the best source would be through legitimate sources such as online stores or software developers. Of course, if you’re running on a bit of luck and happen to stumble upon any promotional offers then do take advantage of those too! However, always remember that pirate sources can never guarantee an easy escape from unverified keys due to the rapid changes made by Microsoft towards improving its security measures against piracy attempts – so use them at your own risk!
