Change the value of Win32PrioritySeparation to 26 hexadecimal, which is 38 decimal
(This tweak is impossible to explain without getting into the technical ins and outs of binary values, bit pairs and bit masks. Suffice it to say, it forces short, variable length processor timeslices to be allocated to foreground processes three times more often than those timeslices given to background processes.
As with the cache tuning tweak (#2), this particular tweak should not be applied to a system that is running either SQL Server or Internet Information Server (IIS) unless you are certain that you want to slow down those background processes.)

Set the value of MenuShowDelay to 0

NtfsMftZoneReservation = 2 (if there are many files on a partition, the master file table (MFT) can get fragmented, with this tweak there will be no more fragmenting of the file master file table (default value = 1, range 1-4).
