ReadyBoot set to start after Windows 8.1 update

My system drive is an SSD. After updating from Windows 8 to 8.1, the registry changed so that ReadyBoot start value is "1" instead of "0". According to OCZ, it should be "0" when your system drive is an SSD.

According to OCZ, running Windows Experience Index sets your ReadyBoot parameter correctly. But WEI has been removed from Windows 8.1. So how can I get this registry key set properly? I don't think it can be manually edited because I tried that in Win 7 and it wouldn't take.

ReadyBoot uses data from 5 previous boots to create a plan for a boot-time memory cache. It will try to preload files into RAM before they are needed. All memory used by ReadyBoot is automatically released 90 seconds after booting up, or immediately if another service needs it, so it doesn't have negative performance consequences.

In other words, on an SSD system, ReadyBoot may not improve boot times by a lot, but it will utilize your fast RAM for what it's good for: serving as a fast cache for the disk. And even the fastest SDDs are still slower than RAM memory - disabling it would still make your booting slightly slower.

SO. You'd better not worry and keep it anyway. And guys in OCZ... OVERcautious.


IF you still want to disable it, here you go:

1) go to Administrative tools -> Performance monitor
2) on the left pane find Data Collector Sets -> Start Up Event Trace Sessions
3) on the right pane find ReadyBoot, double click it
4) go to Trace Sessions tab and there UNCHECK "Enabled"
5) done

That's interesting information. Since I posted this, I learned ReadyBoot is disabled by running "Winsat formal –v" from the command prompt. This is the same as running Windows Experience Index in Windows 8.
