Microsoft will release nine patches next week to fix high-risk vulnerabilities.

Microsoft will release nine security patches next week, six of which are used to block high-risk vulnerabilities on its Windows, Office, IE, and development tool Visual Basic.

The patches will be released next Tuesday, according to the IDG News Agency. The second Tuesday of each month is the monthly patch release day set by Microsoft.

Other patches are used to fix vulnerabilities with low security threat levels on Windows, Windows Vista, Microsoft Virtual PC, and Virtual Server.

For the system administrator, August seems to be a busy month. Microsoft released only six updates in July. So far this year, Microsoft has released about 7 patches each month on average.
