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. Ready Boost on 32-bit editions
 now supports up to 256 gigabytes of extra allocation. The default 
setting for User Account Control in Windows 7 has been criticized for 
allowing untrusted
 software to be launched with elevated privileges without a prompt by 
exploiting a trusted application. Microsoft's Windows kernel engineer 
Mark Russinovich acknowledged the problem, but noted that malware can 
also compromise a system when users agree to a prompt. Windows 7 also supports images in RAW image format
 through the addition of Windows Imaging Component-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 Windows Media Center.
