power-on Reduce progress bar wait time

On the boot, the system to run several laps in the progress bar, making the boot time lengthened, the following two strokes can be resolved.
Method 1:
Open Registry Editor, navigate to Hkey_local_machinesystemcurrentcontrolsetcontrolsessionmanagermemorymanagementprefetchparameters " The key value of the Enableprefetcher under the branch is modified to "1" to achieve. This can reduce the number of pre-read files, reduce the progress bar wait time, the effect is the progress bar run a lap into the login screen.
The key value of the Enableprefetcher key in the registry can be set to the following values. The meanings are:
"0"--Cancel the pre-read function;
"1"--the system will only read the application in advance;
"2"--the system will only read the Windows system files in advance;
"3"-the system will read the Windows system files and applications (the default values for Windows XP).
Method 2:
First, open Device Manager, double-click to expand IDE Ata/atapi Controller, and then double-click Primary IDE Channel (primary IDE channel) to change the device type for device 1 at the advanced setting from automatic detection to none. The secondary IDE Channel (Secondary IDE channel) is also handled in the same way. Of course, this is only suitable for users who have only one hard drive and one optical drive, and are connected to the two IDE interface Master disk locations respectively. If you have more than two hard drives (or other devices), make different settings according to the corresponding primary and secondary connection. Device types that are automatically detected can be set to none. Note that if it is set to no more than the next hard drive to be changed back, it may be recognized as the method. Since WinXP automatically detects devices on all IDE channels at startup, it takes longer to search for IDE channels that do not have a device, setting the unused IDE channel to "none" to shorten the detection time and naturally speeds up the startup speed. If your IDE hardware device stays the same for a long time, try it.
