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

Post by Code-Curio » Sun, 15 Nov 2009 23:13:48

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)

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:

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.

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

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.

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
problem <grin>. I was aware of the update and there was a reason for
waiting, but let's not get OT.

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).

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.
