    Help needed Defrag Dual Boot System


    I have a dual boot system Windows 8.1 that came preinstalled and Windows 7 where I do all my work.
    Lately my computer started to slow down slightly especially at start. I checked System Configuration startup and found only five applications that is needed like sound...... I thought I would buy a HD defrag application and use it from now on. I am not a computer expert like most of the people here so I thought I should seek an expert advice on whether is it safe to use these application or the chance is there that they could ruin my system, especially if I run boot time defrag.

    I will appreciate any advice in this.

    Windows 8.1 own Optimize Drives and windows 7 Defragmenter are enough. The can be set to a certain time or manually activated. A lot of the 3rd party defragmenters do not use Windows APIs and are not VSS aware and can mess up restore points and copies of files, The 3rd party software developers say theirs defrags even more because windows own performs a partial defragmentation by consolidating only file fragments that are less than 64MB in size, but there isn't any proof any where that defragging beyond this gives any performance increase, if anything it wears out the disk faster. So I recommend sticking with windows own, and saving your money and disk.

    Some Command Line(Admin.) commands to get the best out of Windows defragmenter:

    Windows Boot Optimization
    Code:
    defrag c: /b /v /u
    Windows Space Consolidation
    Code:
    defrag c: /x /v /u
    1. c: is the system drive(you can change it to any drive/partition letter you need/want.
    2. /b is for boot defrag and arranges you files need for booting windows.
    3. /x is for empty space consolidation so reducing further fragmentation of files and programs by giving them more free space to grow/write
    4. /u lets you see the progress in the command prompt
    5. /v is for the statistics

    This: Disk SpeedUp - Free Defragmenter to Defrag Disk for Best Performance | Glarysoft never made me any problems, it's even SSD friendly. I would not advise doing it too often, any defragmenting puts a lot of stress on disks.

    Thank you for your advise, I will also try your suggested programs, if Cliff's solution did not improve the performance because I really need to speedup my boot time and program access time.

    Appreciate your taking the time to help me.

    @ dabour,
    I made you a zip file containing a batch file that uses the commands I wrote about above, but they do it one after the when you double click the shortcut(Note: it can take awhile).
    Just extract it to Documents, move the shortcut to desktop if you wish. The instructions shows you how to add drives and/or partitions. After adding them just save the batch file again.

    Cliff S,

    Once more Thank you for your time, I appreciate that very much. I used the two commands you wrote earlier and the change that I can comfortably say it happened is the access time for the applications. Booting the computer still needs around five minutes to reach the desktop only. I will try the batch file you kindly sent and let you know.

    Cliff S,

    Hope you will excuse me for being absent this time, we had some unplanned work to deal with that prevented me from trying the file you kindly gave me. Now I run the file and the result was good, from previous experience with defrag application I could say it gave better results, while accessing my applications and files, on the other hand running the .bat file gives error (0x8900001A) which is explained as "boot optimization must be run on the boot volume", and I do not know how to do this, because I do not have a special boot volume, or at least I can not find it in Windows Disk Management.
