In August 2021, we purchased Windows 10 Enterprise LTSB 2016 65 bit. Sofrwarekeep had the best price we could find on the web. We downloaded the product and successfully installed it but but the provided product key would not associate with program we tried to register. After considerable on and off communications, repeated clean installations and online troubleshooting with the company representatives, SofwareKeep provided me with a different product key. This too would not associate with the program. SofwareKeep then refunded me the purchase price. Overall, I lost considerable time during the repeated installations and troubleshooting and was delayed in my work. We turned to a different vendor, trustedtechteam.com Their product was marginally more expensive but it installed cleanly and the correct product key became associated with the version I installed.
