只要用文本编辑器编辑如下一个文本文件：
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE＼SYSTEM＼CurrentControlSet＼Control＼Session Manager＼Memory Management＼PrefetchParameters]
"VideoInitTime"=dword:0000033c
"EnablePrefetcher"=dword:00000001
"AppLaunchMaxNumPages"=dword:00000fa0
"AppLaunchMaxNumSections"=dword:000000aa
"AppLaunchTimerPeriod"=hex:80,69,67,ff,ff,ff,ff,ff
"BootMaxNumPages"=dword:0001f400
"BootMaxNumSections"=dword:00000ff0
"BootTimerPeriod"=hex:00,f2,d8,f8,ff,ff,ff,ff
"MaxNumActiveTraces"=dword:00000008
"MaxNumSavedTraces"=dword:00000008
"RootDirPath"="Prefetch"
"HostingAppList"="DLLHOST.EXE,MMC.EXE,RUNDLL32.EXE"
然后将该文本文件保存为注册表文件再导入到系统中就可减少滚动条的滚动次数(请注意，在上述文本中，第一行Windows Registry Editor Version 5.00下面必须有一空行)。系统重启后即能生效，滚动条将减少到1次稍多一点。
