Microsoft: Don't press F1 key in Windows XP

Microsoft told Windows XP users today not to press the F1 key when prompted by a Web site, as part of its reaction to an unpatched vulnerability that hackers could exploit to hijack PCs running Internet Explorer (IE).

Windows 2000, Windows XP and Windows Server 2003 are impacted by the bug, said Microsoft, and any supported versions of Internet Explorer (IE) on those operating systems.

Until a patch is ready, users can protect themselves by not pressing the F1 key if a Web site tells them to, said Microsoft.
