Microsoft
warned consumers Wednesday about four critical new flaws in its popular
Windows software as the company shifted to monthly alerts for serious
problems that could let hackers break into computers. In particularly
embarrassing disclosures,

Microsoft acknowledged problems in its technology to authenticate software
publishers over the Web and in its Windows help and support system.

The company said it did not believe hackers were yet exploiting any of
the vulnerabilities it announced.
