Microsoft on Wednesday told users to immediately install an emergency Windows update after it identified a security flaw in the operating system.
The vulnerability, called PrintNightmare, allows attackers to infiltrate users’ systems through the Print Spooler service, which enables multiple users to access a printer. Attackers could exploit the flaw relatively easily to install programs; view, edit, or delete data; or create new user accounts, Microsoft said Tuesday.
The security issue affects all supported versions of Windows, and Microsoft has labeled the emergency update as critical.

“We recommend that you install these updates immediately,” the tech giant said.
Microsoft on July 1 said it was aware of the vulnerability and was investigating it. The fix comes amid a new wave of large-scale cyber attacks.
Microsoft’s own systems were breached – along with those of software juggernauts Intel and Cisco – during the massive SolarWinds hack, discovered in late 2020. Colonial Pipeline, which operates a critical US fuel pipeline, paid out nearly $5 million in bitcoin to hacker group DarkSide after a devastating ransomware attack in May.
