    Hello

    I am going to reinstall Windows soon and I am wondering if I can 'keep' my
    updates, esp as I may not have a Broadband connection immediately.

    I have found the folder C:\WINDOWS\$hf_mig$ which seems to have the
    correctives.

    I've noticed an 'update.exe with each corrective and I am wondering if this
    can be clicked on.

    Finally, I assume that the correctives are still valid whatever the changes
    made to the computer (new motherboard and processor in this case).

    Can sm please confirm or put me straight?

    Thanks

    software update packages

    From the above article:-

    When a security update, critical update, update, update rollup, driver, or feature
    pack installs GDR version files, the hotfix files are also copied to the
    %windir%\$hf_mig$ folder. This supports migration to the appropriate files if you
    later install a hotfix or service pack that includes earlier versions of these files.
    For example, consider the following scenario:

    1. You apply a security update that installs a GDR version of File.dll with a
    version number of 5.2.3790.1000 and copies a hotfix version of File.dll with a
    version number of 5.2.3790.1000 to the %windir%\$hf_mig$ folder.

    2. You apply a hotfix that includes a hotfix version of File.dll with a version
    number of 5.2.3790.0000.

    In this scenario the hotfix installation in step 2 installs the hotfix version of
    File.dll (version number 5.2.3790.1000) from the %windir%\$hf_mig$ folder instead of
    the hotfix version of File.dll (version number 5.2.3790.0000) from the hotfix
    package.

    Hi

    I guess it is when for instance you get a CD with a magazine or product and
    you click on an update or even an .exe

    Sometimes, the CD supplied with a peripheral can be over two years old in my
    experience.

    Regards

    Hello

    I think I've understood why the updates etc are there (in case the files are
    needed again when applying another update etc)

    But does this mean that once I have my computer up and running, I will have
    to go on line to get install all the fixes again.

    This seems weird as some of the fixes are security issues.

    More importantly, as the computer will have the same 'name', will Microsoft
    (the system) know that the updates I had downloaded in the past are no
    longer installed on the computer and send them again???

    Maybe I should buy a CD with crtical updates to get them without being on
    line and vunerable???

    Please advise

  5. Download the updates you need from a friend's computer.

    You can download them from the Catalog and save to be installed later.
    http://v4.windowsupdate.microsoft.com/catalog/en/default.asp

    Click Add button for each update you want to download. Once you have what you want,
    Click the "Go To Download Basket" link. Type in or browse to the location where you
    want the updates saved to and then Click the "Download Now" button.
    Once downloaded, you can then burn them to CD.

    If you're wiping the HD, then you will need to reinstall the updates. WU should
    detect that the updates are not on your computer.
    If you are reinstalling over the previous installation, then that's different.

    You can get a printout of what updates you have installed prior to wiping the
    computer.
