How to fix printing PrintNightmare print issue
PrintNightmare is a critical vulnerability that affects the Print Spooler service, which is pre-enabled on all machines. As you probably know, this service is required for printing, and it is also enabled on devices that are not connected to printers. According to reports, the Print Nightmare vulnerability is actively used by attackers to obtain local privileges and remotely execute code on the affected machines. This vulnerability was discovered last week after security researchers accidentally published the exploit code on GitHub. In this regard, Microsoft has started to release an emergency update of Windows 10 KB5004945 to fix the security error PrintNightmare, affecting all supported versions of Windows 10. Since the Print Spooler service is enabled in Windows by default, Microsoft has released a patch for Windows Server 2019, Windows Server 2012 R2, Windows Server 2008, Windows 7, Windows 8.1, Windows RT 8.1 and supported versions of Windows 10.
