I found many error in Evenvwr log, i.e:
message "Windows Defender Real-Time Protection agent has detected changes. Microsoft recommends you analyze the software that made these changes for potential risks. You can use information about how these programs operate to choose whether to allow them to run or remove them from your computer. Allow changes only if you trust the program or the software publisher. Windows Defender can't undo changes that you allow"
2) Service Control Manager Event Log provider.
"The Parallel port driver service failed to start due to the following error: The service cannot be started, either because it is disabled or because it has no enabled devices associated with it."
3) Http Event "Unable to initialize the security package Kerberos for server side authentication. The data field contains the error number".
