Start, Shutdown, and Resume
Windows 7 is ready when you are. It’s designed to start, hibernate, and shut down faster than Windows
Vista. We also focused on ways to resume from sleep more quickly and reliably. And because resuming
from sleep is much faster than rebooting your PC, you can use sleep when you really need your PC to
come to life quickly.
Search and Indexing
When looking for information, you want answers, not delays. Search and indexing are both much faster
now, because Windows 7 includes all the performance improvements from Windows Search 4.0, a
Windows technology that indexes all the les on your PC, as well as several other signi cant new perfor-
mance optimizations. Sorting and grouping of search results are signi cantly faster too. (See pages 34–37
for a more detailed discussion of improvements to Windows Search.)
ReadyBoost
PCs that are low on memory frequently swap data to disk, which can make performance lag. With
Microsoft ReadyBoost™ technology, which we introduced in Windows Vista, you can use a ash memory
device to cache frequently used data, which in turn makes your PC more responsive. With ReadyBoost in
Windows 7, you can use multiple ash devices—such as USB keys, Secure Digital cards, and internal ash
devices—at the same time.
Improved Memory Utilization
We’ve worked hard to reduce overall memory requirements in Windows 7. For example, hundreds of
runtime components now use less memory, while the core memory needs are smaller when the computer
is idle. Windows 7 can reduce the memory requirements for each open window by up to 50 percent. In
addition, we’ve introduced trigger start services, an innovative feature that launches system services only
when they’re needed and reduces the number of programs competing for system memory.
Solid State Drives
Solid-state drives (SSDs), an alternative to traditional hard disk drives, are becoming more popular. This
popularity is partially due to the fact that SSDs are typically faster than conventional hard disk drives. We
designed Windows 7 to work well with SSDs so you’ll have a chance to experience improved PC perfor-
mance, more consistent responsiveness, increased battery life, superior ruggedness, quicker startup
times, and reductions in noise and vibrations. Features such as disk defragmentation, Microsoft Super-
Fetch™ memory management technology, and ReadyBoost (described above) are designed to improve
system responsiveness and performance when data is being retrieved from traditional hard disk drives. In
Windows 7, these features respond to a computer’s con guration and automatically turn themselves off
for the newer, faster SSDs, where they are not necessary, which helps free up system memory.
