Facepalm: Microsoft is once again advising its customers to disable Windows print spooler, after a new vulnerability that allows hackers to execute malicious code on machines has emerged. While a patch fixing the flaw will be released in due course, the most effective workaround currently on the table is to stop and disable the print spooler service entirely.

This is the third print spooler vulnerability to emerge in just five weeks. While a critical flaw was originally identified and patched in June, a similar flaw – dubbed PrintNightmare – came to light shortly after and was subsequently patched (with mixed success).

The emergence of this new vulnerability is frustrating news for Microsoft and its users.
