improve your computer performence

Navigate to HKLM\\System\\CurrentControlSet\\Services\\NTFS\\EFS\\Parameters and set theparameter of EFSKCACHEPERIOD to a value between 2 and 30. default is 5. Value suggest the timein seconds the kernel will cache the session key for a user for a given file. The Kernel will not validatethe user credentials during this cache period. This has the net effect of faster access to encryptedfiles that may be opened several times during a given time period.This is helpful in kernel and user mode of the EFS (encrypting file system) as it provides quicker access to frequently use components.Similarly navigate to HKLM\\Software\\Microsoft\\Windows NT\\CurrentVersion\\EFS and set thevalue of KeyCacheValidationPeriod to a value in units of second from 1 minute to 1 day (60 to86400).Microsoft has an interesting article on this at Registry Keys Used to Tune EFS Caching (Q278256).Read it for complete details

CHKNTFS is the command used to set the AUTOCHK initiation count down time. You can reduce it
from default 9 seconds to a much lower value say 4 seconds. Go to command prompt and typeCHKNTFS/T:4 This command would set the AUTOCHK initiation count time down to 4.

 MFT fragmentation. So what is the cause of fragmentation.common cause is too much use. As with anything excessive use causes fragmentation.Activities of add/update/delete to a section of disk would invariable cause it to fragment. So there isno permanent solution as we can not avoid these acts. As such it is a good idea to use diskdefragmenter regularly. Contiguous data which results from defragmenting disk, improves systemperformance considerably. But what I am suggesting you here would prolong intervals betweendefragmentations resulting in more time for your own productive work. OK! This tip is for those folkswould never be using a DOS based program or don't care for connection from DOS based operatingsystems (example: old games and all things before windows 95). In Windows XP, two file names arecreated for each file one is the actual name and another one is 8.3 version of that file name for compatibility with DOS based programs. Now this work name in the name of compatibility takes quitea lot of system resources specifically CPU time and disk space.But this is not it, it also increases your MFT utilization and fragmentation. So the solution is to disable it. How to do this ? Open Registry bygoing to START-RUN and entering REGEDIT and Navigate toHKEY_LOCAL_MACHINE\\System\\CurrentControlSet\\Control\\FileSystem. In right pane, look for key by the name "NtfsDisable8dot3NameCreation" and sets its value to 1. Thats it. You would seeimprovement in system performance for sure.
