It is the second Tuesday of the month, and that means patch day over at Microsoft. Windows systems configured to automatically update should pick up the updates on the next start of the system. Users who do not want to wait that long can run a manual check for updates instead. On Windows 7, users need to click on Start, enter Windows Update in the run box and select the first entry with that name in the listing.
The Windows Update control panel applet opens, where a click on Check for updates in the sidebar runs the manual update check. If everything works out, you should see the available updates increase in the main pane of that window.
You can click on the update links to manage the updates before installation, or click on the Install updates button right away to start the downloading and installation of the selected ones on the system. Please note that you need to restart the computer after the updates have been installed to complete the process.
For more information on the process and alternatives, check out our Windows Update guide.
Microsoft has released a total of six security bulletins in April 2012 that fix vulnerabilities in a variety of Microsoft products. Products include Microsoft Office, Microsoft Server Software, SQL Server, Microsoft Windows, Internet Explorer and the Microsoft .Net Framework.
Four of the bulletins have received a maximum severity rating of critical, the highest possible rating, while the remaining two one of important, the second highest rating. The actual severity rating depends on the version of the software and the underlying operating system, and may differ as a result of this.
When you look at the deployment priority, Microsoft suggests to install the bulletins MS12-027 and MS12-023 first, then Ms12-024, MS12-025 and Ms12-08, before installing MS12-026. Why those two critical vulnerabilities first? Because the vulnerability that MS12-07 addresses is actively exploited, while Ms12-023 is covering an industry-wide issue.
The security updates have been uploaded to Microsoft's Download Center from where they can be downloaded.Advertisement
