    Hello FerchogtX,

    Defragging the registry is basically a method to remove wasted space in registry, and is fine to do.

    Cleaning the registry is to remove what is believed to be invalid registry entries. Some software are more aggressive at this than others, and can often remove registry entries that it shouldn't causing issues. Personally, I would strongly recommend to never clean the registry for this reason. Especially since you will not notice any performance difference.
    Hello Shawn now mate does that go for 7 installs as well and I use the CCleaner for checking the reg in 7 and 10 is it a no no??

    Defrag is fine, but never clean the registry.

    Personally, I wouldn't do either one considering how much of a disaster it would be if the registry was messed up, and how very little you would gain from a defrag.

    I was just curious(and a little bored... so), of what the printed & verbose output would be when retrim was done, so here it is to share.
    Command was defrag c: /l /v /u
    "L" being the retrim command for C:

    You can then see how much of your SSD was trimmed.

    Hello,

    my drive's fragmentation status won't go below 20% (C: drive). What gives? Not a SSD.

    Hello,

    It could be your Pagefile, hyberfil, swapfile and system volumn information that are fragmented, and cannot be defragment inside of Windows.

    Here is what I used to do to get a better defrag, when I used HDDs:

    First I installed Defraggler from Piriform: Defraggler - File and Disk Defragmentation - Free Download
    So I could defrag in safe mode(Optimize drives doesn't function in safe mode, so you need a 3rd party defragmenter)
    In Advanced Settings(Control Panel\All Control Panel Items\System)I would shut of system restore temporarily and delete all restore points by turning System Protection off:

Views: 222
Size:  16.7 KB

    Then I would turn off the page file(virtual memory).

    Then boot into safe mode, run Defraggler, and before booting back into Windows, select Defragglers Boot-Time Defrag***\run once, which allows you to defrag files that are normally locked by the Operating System before the operating system is fully loaded.

    Then you can turn Page file, and system restore back on(remember to create a restore point immediately after).
    ***Boot-Time Defrag – defrags the system disk during the boot time, before the whole operating system is loaded. This allows Defraggler to defrag the files which are blocked after the operating system is loaded. At the moment following files are defragmented during the boot time defrag:

    • C:\pagefile.sys
    • C:\WINDOWS\system32\config\AppEvent.Evt
    • C:\WINDOWS\system32\config\default
    • C:\WINDOWS\system32\config\SAM
    • C:\WINDOWS\system32\config\SecEvent.Evt
    • C:\WINDOWS\system32\config\SECURITY
    • C:\WINDOWS\system32\config\software
    • C:\WINDOWS\system32\config\SysEvent.Evt
    • C:\WINDOWS\system32\config\system
    Piriform - Boot Time Defrag

    You can defrag system disk outside of Windows for the best results.

    Boot Windows USB - Repair - Troubleshoot - CMD - type/enter:

    c:
    cd windows
    cd system32
    defrag c: /u

    figured out that it wont defrag large files in windowapps folder.
    had a 4gb game file in windowsapps and it was at the front of drive.
    had to bypass security to gain access to the folder and then use O&O defrag and it moved it to a different spot on the drive.

    actually I dont think windows built in defrag likes defragging large files.

    I been using auslogics defrag to do quick defrags. and it always defrag large files and puts them some where else.

    but for some reason auslogic wont touch the windowapps folder.

    So Shawn do you think I shouldn't check the reg with CCleaner in 7 or 10?? as I always back up the results to merge back if I mess up?? Plus I back up the original install registry whenever I do reinstall??

    As I don't have any spinners to think about much I would do a defrag on my SSD's at all.
