Windows 10 users around the world have been experiencing an activation problem since last night. Some parts of Windows 10 shift Windows 7 to Windows 10.
Some of our stakeholders spoke at our forum. On Twitter, you can find different messages and have been in Reddit for a long time (through WindowsUnited). Reported that the victim was talking to Microsoft and communicating with Microsoft. Probably worked on the solution.
You can now offer the best advice: just do not do anything and wait. The problem is self-destructive and self-destructive. The affected computers will not burn immediately.
update: Most users reported that their systems were "re – activated" again. The problem is already resolved, but may only be visible in the next few hours.
