    I bought Windows 10 Pro OEM key and the as soon as I completed the payment a new tab opened in my mobile Chrome browser containing all the payment details and the windows key with a guidance link. I headed over to my desktop to put the key and voila!! It worked like a charm….no complaints anywhere. The whole activation process took less than 3 minutes. After 5 minutes or so I got a mail from delta keys containing all my payment details and the key which I flagged for future reference. So surely all the skeptical people out there, you can go for it.

    My experience –
    I was also very skeptical about these websites(which sell cheap windows keys) at first. I researched a lot before making any payment in quora, reddit, superuser etc…and everywhere I found a green signal for delta keys. Then i visited the website both in mobile and pc…to look for any suspicious activity. But found none. As they have dedicated customer chat support, mail support and instant key delivery system. When I found these details to be satisfactory then i contacted their chat support in WhatsApp and cleared all my queries first like what key to buy, what OS is the right one, does OS version make any compatibility issue etc. The support person was very polite, calm and friendly. After clearing all my doubts and queries I made the payment.

    So 5star for them. Will buy from this website in future again.

    I was skeptical about purchasing software from an online store I had never heard of, but the reviews for Delta Keys were great so I decided to give it a try. I’m happy to say that the process was easy and straightforward, and the software I purchased is working perfectly.

    I needed Windows 10 Pro to rebuild a 9-year-old laptop with a damaged copy of Windows 7 that wouldn’t boot. Getting the license key from was quick and painless, and getting an ISO file of installable Windows 10 for DVD was only slightly harder, i had to download the setup file from microsoft website. I was installing Win 10 Pro on the laptop less than an hour after purchasing the license key.
