windows 7 includes a number of new features, such as advances in touch and
handwriting recognition, support for virtual hard disks, improved
performance on multi-core processors,[36][37][38][39] improved boot
performance, DirectAccess, and kernel improvements. Windows 7 adds support
for systems using multiple heterogeneous graphics cards from different
vendors (Heterogeneous Multi-adapter), a new version of Windows Media
Center,[40] a Gadget for Windows Media Center, improved media features, the
XPS Essentials Pack and Windows PowerShell being included, and a redesigned
Calculator with multiline capabilities including Programmer and Statistics
modes along with unit conversion. Many new items have been added to the
Control Panel, including ClearType Text Tuner, Display Color Calibration
Wizard, Gadgets, Recovery, Troubleshooting, Workspaces Center, Location and
Other Sensors, Credential Manager, Biometric Devices, System Icons, and
Display. Windows Security Center has been renamed to Windows Action Center
(Windows Health Center and Windows Solution Center in earlier builds), which
encompasses both security and maintenance of the computer. The default
setting for User Account Control in Windows 7 has been criticized for
allowing untrusted software to be launched with elevated privileges by
exploiting a trusted application. Microsoft's Windows kernel engineer Mark
Russinovich acknowledged the problem, but noted that there are other
vulnerabilities that do not rely on the new setting. Windows 7 also supports
Mac-like RAW image viewing through the addition of WIC-enabled image
decoders, which enables raw image thumbnails, previewing and metadata
display in Windows Explorer, plus full-size viewing and slideshows in
Windows Photo Viewer and Window Media Center.
