    Hi is it possible to delete any unnecessary files from win 7 iso so that it can fit on a 4 gb pendrive.
    i am using a preactivated win 7 iso with DVD/USB tool but is saying insufficient memory.

    Unfortunately, you will get an insufficient space error when DISM'ed with hotfixes. Without removing stuff, a bigger USB pendrive is required.

    You can always do a compression of install.wim file with DISM.

    agree, this is what i use to create a newly compressed install.wim

    Code:
    Dism /Export-Image /SourceImageFile:D:\inject7\install.wim /SourceIndex:1 /DestinationImageFile:D:\inject7\install2.wim
    
    Dism /Export-Image /SourceImageFile:D:\inject7\install.wim /SourceIndex:2 /DestinationImageFile:D:\inject7\install2.wim
    
    Dism /Export-Image /SourceImageFile:D:\inject7\install.wim /SourceIndex:3 /DestinationImageFile:D:\inject7\install2.wim
    
    Dism /Export-Image /SourceImageFile:D:\inject7\install.wim /SourceIndex:4 /DestinationImageFile:D:\inject7\install2.wim

    I tested in this section a few months ago and the result is interessting.
    I'm sure you can even cut also all or moste fonts... I usually only cut the foreign language fonts.

    My whole DVD (mixed Win7 and Win8 - I'm using custom Win81 boot.wim with Updated Win7SP1 - (yes higher PE can be used (also the Win8/81 Setup-Wizard) to install Win7 Wims)
    Code:
    \bootmgr| Not needed if you use EFI
    \bootx64.efi| Optional (moved the file as this is easier to select the file from root for boot)
    \setup.exe
    
    \boot\bcd
    \boot\boot.sdi
    \boot\bootfix.bin | can be deleted (is the promt to type some key)
    \boot\bootsect.exe| can be deleted 
    \boot\de-de
    \boot\etfsboot.com| can be deleted 
    \boot\fonts
    \boot\memtest.exe| can be deleted 
    \boot\resources| can be deleted (from Win8/81)
    \boot\de-de\bootsect.exe.mui| can be deleted
    \boot\fonts\malgun_boot.ttf| I guess it can be deleted (all ttfs)
    \boot\fonts\malgunn_boot.ttf
    \boot\fonts\meiryo_boot.ttf
    \boot\fonts\meiryon_boot.ttf
    \boot\fonts\msjh_boot.ttf

    \boot\fonts\segoe_slboot.ttf
    \boot\fonts\segoen_slboot.ttf
    \boot\fonts\wgl4_boot.ttf
    \boot\resources\bootres.dll| can be deleted (from Win8/81)
    
    ######## Whole EFI Folder only neede for EFI
    \efi\boot\bootx64.efi| same file as in root of the drive
    \efi\microsoft\boot
    \efi\microsoft\boot\bcd
    \efi\microsoft\boot\cdboot.efi
    \efi\microsoft\boot\cdboot_noprompt.efi
    \efi\microsoft\boot\efisys.bin

    \efi\microsoft\boot\resources\bootres.dll
    
    ######## Yes those are the only files that are needed to install a fresh image (no migration)
    \sources\boot.wim
    \sources\install.wim

    That is just a template. Place your own file locations in it.

    Code:
    Dism /Export-Image /SourceImageFile:D:\inject7\install.wim /SourceIndex:1 /DestinationImageFile:D:\inject7\install2.wim
    
    could be changed to 
    
    Dism /Export-Image /SourceImageFile:C:\Proiject\install.wim /SourceIndex:1 /DestinationImageFile:C:\Proiject\install2.wim
