Page 837 - Windows 10 May 2019 Update The Missing Manual: The Book That Should Have Been in the Box

If you press F10 instead of choosing one of those nine options, you’re

offered the chance to return to the Windows Recovery Environment. If you
press Enter, you start the operating system in its usual fashion, exactly as
though you’d never summoned the Startup Settings menu to begin with. It
lets you tell the PC, “Sorry to have interrupted you…go ahead.”

Thanks to these powerful startup tools, there are fewer reasons than ever to
pay $35 for the privilege of talking to some technician following a script.

Two Obscure Speed Boosts

Every PC seems to get slower the longer you own it. Fortunately, in

Windows 10, here and there, nestled among the 50 million lines of code,
you’ll find a couple of free tricks that may give your PC a speed boost:

SuperFetch attempts to keep your most frequently used programs
in RAM (memory), ready to go, all the time, based on your work
patterns.

ReadyBoost lets you use a USB flash drive as an additional cache
(a chunk of superfast memory) for frequently used data.

For details on both features, see the free PDF appendix to this chapter
called “Two Speed Boosts.” It’s on this book’s “Missing CD” at

missingmanuals.com.
