Here's the text of an email I received from a vendor:
Please take a moment to review this briefing from Microsoft:
Many users of Windows 10 systems are suffering from an activation error that causes their systems to be listed as inactive. In the company's post supporting BBS, user Daniel Randy revealed that Microsoft support had confirmed to him that this was a problem that was common in multiple countries. Microsoft engineers advise users to wait up to two days until the solution is resolved, and contacting support now may not help. Microsoft just released a new issue bulletin on the current activation issues related to the Windows 10 Pro version. This is happening in Japan, South Korea, the United States and many other countries, "a Microsoft support engineer posted on community BBS. "I regret to inform you that Microsoft currently has a temporary problem with the activation server that some customers may encounter, where Windows appears to be inactive. Our engineers are working overtime to solve this problem and it is expected to be corrected within one or two working days. "The number of people reporting problems is growing every minute, which may indicate that this is a serious problem worldwide. Some users also reported that their copy of Windows has been downgraded from Windows 10 Pro to Windows 10 Home. However, this seems to be a relatively rare behavior. Microsoft has yet to provide any other details and expects the number of users to continue to grow in the coming hours.”
Hopefully this issue will be corrected in the next 48 hours, we will keep you updated with any other news.
