These are the tweaks 14 21 next in line to be added, if you want anymore please say... //Mouse Hover Time HKEY_CURRENT_USER\Control Panel\Mouse MouseHoverTime="20",String //Double Mouse Speed HKEY_CURRENT_USER\Control Panel\Mouse MouseSpeed="2",String //Enable Large System Cache HKLM\System\CurrentControlSet\Control\Session Manager\Memory LargeSystemCache=0,DWORD If the Large Cache option is on, the manager marks all the free memory, which isn't being used by the system and/or applications, as freely available for disk caching. On the flip-side (with a small cache), the manager instead only sets aside 4MB of memory for disk caching in an attempt to accelerate the launch of applications. Or in a more technical approach, if enabled the system will favor system-cache working sets over process working sets (with a working set basically being the memory used by components of a process). //Disbale Superfetch HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session Manager\Memory Management\PrefetchParameters EnableSuperfetch=-,DWORD //Disable Prefetch HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session Manager\Memory Management\PrefetchParameters EnablePrefectcher=0,DWORD //Increase Icon Cache HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer Max Cached Icons= 2048,DWORD //Disable Paging of Kernel HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management DisablePagingExecutive=1,dword Disable Paging Executive This will prevent pages sections from RAM going to the hard drive. If you have a large amount of RAM at least 256Mb (I suggest 512) you might want to keep the data in your RAM to improve your performance considerably due to reduced amount of hard drive swappage. //Block Negative DNS Entries HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters MaxNegativeCacheTtlValue=0,Dword To force Windows 7 NOT to cache negative entries //Keep Positive DNS Entries (4 Hours) HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters MaxCacheTtl=14400,dword To force Windows 7 to keep positive entries in DNS Cache for only 4 hours instead of the default 24 hours //Show System Files HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced ShowSuperHidden=1,dword //Always Unload DLL HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer AlwaysUnloadDLL=1,dword Explorer does not unloadDLL files from memory right away. They always remain in the memory for a period of time that is often quite lengthy. To unload DLLs when you are done with them navigate to //Enable Boot Defrag HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOptimizeFunction Enable=Y, string //Disable Last File Access Timestamp HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem NtfsDisableLastAccessUpdate=1,dword //Disable 8.3 Name Creation [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem] "NtfsDisable8dot3NameCreation"=dword:00000001 Short names is something that is needed for DOS compatibility. Most of us will want to turn this off. The only time you'll want to leave this on is if you are supporting DOS or win 3x based clients. //Enabled Avalon Effects HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\explorer "MILDesktop"=dword:00000001 "MILExplorer"=dword:00000001 ; Disable Tool Tips [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced] "ShowInfoTip"=dword:00000000 ;get rid of the Windows Mail splash screen [HKEY_CURRENT_USER\Software\Microsoft\Windows Mail] "NoSplash"=dword:00000001 Disable Windows Media Player AutoUpdates [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\WindowsMediaPlayer] "DisableAutoUpdate"=dword:00000001 ;faster browsing with IE [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AFD\Parameters] "BufferMultiplier"=dword:00000400 ;Disable automatic restart in the event of a blue screen [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CrashControl] "AutoReboot"=dword:00000000 ;Enable DVD in Media Player Value: Yes or No [HKEY_CURRENT_USER\Software\Microsoft\MediaPlayer\Player\Settings] "EnableDVDUI"="Yes"
