Microsoft is set to tackle a huge number of vulnerabilities on next week's Patch Tuesday.
The company revealed today it would address 34 security flaws through 10 separate bulletins, three of which are marked "critical." The other seven are flagged up as "important."
The critical vulnerabilities are known to affect all versions of Windows, as well as Internet Explorer, while the latter seven cover Windows and Office.
Although Microsoft has warned on its Security Response Centre blog that administrators need to be prepared as always for the patches, the wider security industry is warning users to be extra vigilant.
"The June release is a large update and will keep system administrators busy, even if they have migrated to Windows 7 already," said Wolfgang Kandek, chief technology officer at Qualys, in a statement.
Alan Bentley, international vice president at Lumension, added in a statement: "The impact will be felt enterprise-wide with bulletins covering a large portion of Microsoft's range of operating systems and Windows and Office products."
He added: "It is strongly suggested that IT administrators plan ahead and prioritise this patch load as soon as possible."
Last month's Patch Tuesday only saw two bulletins released, but both were critical updates.
