"Start without add-ons" vs disabling add-ons

Discussion in 'Internet Explorer' started by Code-Curious Mom, Nov 14, 2009.

  1. What is the difference between starting IE8 without add-ons, and disabling
    all of them through 'Manage Add-ons'? Is there something else that "Start
    without add-ons" disables? Add-ons that 'Manage add-ons' does not detect? I
    encountered a webmail app that behaves differently when IE is started
    without add-ons vs disabling them all. (I found a simple acceptable
    workaround for the original issue, so I am more interested in the questions
    as asked rather than solving the issue that prompted this.)

    BTW, I really disabled *all* of them, those in 'Run without permission', and
    'Downloaded controls' in addition to those listed as 'All add-ons', which
    curiously does not seem to actually include some of those in the other

    Thanks. (IE8 on WinXP SP3)

  2. Troubleshooting and Internet Explorer's (No Add-ons) Mode:

    If you really wanna disable all Add-ons in one swell foop (...), do a Reset:

    When you use Internet Explorer 8, you cannot access your Webmail:

    switch back to Yahoo Classic Mail.

    OT: Your headers (Microsoft Windows Live Mail 14.0.8064.206) tell us that
    you're running an outdated version of Windows Live Mail and any other
    Windows Live apps. Current build of Windows Live Mail is v14.0.8089.0726.

  3. Well that's basically what I already tried. Works properly in No Add-ons
    Mode; improperly with all add-ons individually disabled.
    RIES is what I'm trying to avoid. Was hoping to find the individual item
    that was a problem. So far I've determined that it's DEP-related. If it
    ever becomes enough of an issue to justify it, I'll try RIES or other
    suggestions from your links. Thanks for the effort.

  4. Try running ProcMon twice and find out? ; )

    While you're at it tell us what difference just unchecking
    Enable third-party extensions (requires restart)
    i.e., the old IE5 way of doing ostensibly the same thing does?
    And if you still have BHODemon (for example) you could check
    how using it compares with using Manage Add-ons, again comparing
    the old tools with the new.

    Good luck

  5. To keep track of things, it helps immensely if you quote all of the previous
    message(s) in your replies to the newsgroup. Thank you.

    PS: Always state your full Windows version (e.g., WinXP SP3; Vista 64-bit
    SP2; Win7 RC; Win7) as well as your IE version when posting in an
    IE-specific forum or newsgroup. Please do so in your next reply.

    PPS: At least you got Windows Live Mail upgraded.

  6. I finally got this sorted. The difference between 'start without add-ons'
    and individually disabling them all was that 'start without add-ons' was
    also disabling the information bar from prompting for ActiveX downloads.
    (Seems sensible enough, but haven't seen that documented anywhere.) I
    discovered that even with add-ons enabled, if I changed 'Download signed
    ActiveX controls' from Prompt to Disable, no problem occurred. But of
    course that totally prevents ActiveX downloads on all sites in that zone.

    What actually fixed the issue was uninstalling the MS Java VM according to
    the instructions at: http://support.microsoft.com/kb/555107. MS Java is
    ancient; good riddance! I've had Sun Java for ages.

    For the possible benefit of others, the error I was getting was "the
    instruction at <hex address> referenced memory at <same hex address>. The
    memory could not be written." While troubleshooting, I found that in
    addition to webmail (in a particular configuration), the error also occurred
    at http://www.adobe.com/shockwave/welcome/, and when attempting to download
    adobe flash player.

    Ok, sure.
    I did post my Windows & IE version in my first post, as you can see if you
    scroll down.
    Actually, no, I'm not currently posting from the machine that had the

  7. ProcMon is fantastic, thanks for reminding me of this. I am not very
    experienced at using it and was not really quite sure what to look for and
    what to filter out, but I did get some ideas and combining those with
    googling and experimenting finally led to success in fixing the error and
    some insight into the difference ('start without add-ons' was also disabling
    prompting for ActiveX downloads - there may be other differences I've not
    found). BTW, unchecking 'enable third-party extensions' did *not* disable
    the info bar ActiveX prompt (and I would guess third-party extensions would
    not include MS ones).

  8. Really? I would have sworn that used to disable embedded Java applets
    when Java was only MS Java.

    Glad to see you found a resolution. Thanks for the feedback.
