A (new) flaw has been discovered in Windows that Microsoft regards as critical. And they’ve released a patch to fix it. If you’re computer(s) use the following then you need to install the patch now.
- Windows Vista
- Windows XP
- Windows Server 2003
That should cover pretty much everyone using Windows at home and at work, and both servers and PCs.
To apply the patch use Windows Update in Internet Explorer (in the Tools menu), or if your computer is set to automatically download and apply patches then it’ll be applied automatically overnight.
This one’s pretty serious so don’t delay. More information on Microsoft’s web site.
