Try configuring your serial number of the operating system or Windows license, this must coincide with the region or country to which the license belongs, many times this is the cause of the error and therefore does not allow your device to be found, verifies the date and time of the device as well as the time zone and region.
If it does not work and if you have already performed a restart of your computer, the system may have a corrupted registry file, which I recommend you perform a scan of the operating system.
Open the command prompt by pressing Win + R keys and typing CMD in the search box. Or else, in the Windows 10 search box, search for "Command Prompt" and right-click on the result to run as administrator.
Once you have launched the Command Prompt, type the following text and hit Enter:
[php] sfc / scannow [/ php]
In modern processors the process takes about 10 minutes. After the run completes, you may get results that indicate a corrupted file system.
SFC.EXE repairs most problems. However, when SFC fails, a second instrument called Deployment Image Maintenance and Management (DISM) must be used.
