Microsoft will issue three serious Win8.1 security patches on November 12

Computer Store News: Microsoft announced today that it will release some new security bulletins on the next Tuesday patch day, three of which are marked as "serious".

Microsoft said that in addition to these three serious upgrades, it also includes more than five "important" upgrades. As usual, today's announcement did not disclose any details of these upgrades.

Microsoft said these three serious upgrades and two or more of the major upgrades also apply to Windows XP. They will appear in the list of the last upgrades that Microsoft released for Windows XP.

But these upgrades released on Tuesday will not fix the vulnerabilities found in several Microsoft software earlier this week.
