I had some old tweaks, and while sorting through them, I found this Code: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem] "NtfsDisableLastAccessUpdate"=dword:80000003 "NtfsDisable8dot3NameCreation"=dword:00000001 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management] "DisablePagingExecutive"=dword:00000001 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management] "LargeSystemCache"=dword:00000001 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00\0cc5b647-c1df-4637-891a-dec35c318583] "ValueMax"=dword:00000000 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\PriorityControl] "IRQ8Priority"=hex(b):01,00,00,00,00,00,00,00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Update] "UpdateMode"=dword:00000000 Is it still relevant or is it useless ? Thanks PS : LargeSystemCache is useless with SSD I think
