Internet Explorer Plugins and Vista

So I’ve recently got a new machine that came pre installed with Windows Vista.  And now I’ve got the fun task of trying to make everything work again with my plugin 🙂


There are a number of places where I’ve found some good info on this, which I will enumerate here for your and my benefit. – A Developer’s Survival Guide to IE Protected Mode – Inside Windows Vista User Account Control – Understanding and Working in Protected Mode Internet Explorer – Protected Mode in Vista IE7

A couple of key things if you’re relying on the compatibility shims: (described in a little more detail in the 4th link)
Registry Accesses (to HKCU software) are moved to
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\InternetRegistry\REGISTRY\USER\[User security identifier – SID]\Software\[my key]
File accesses (to acceptable locations) are moved to 
 %userprofile%\AppData\Local\Microsoft\Windows\Temporary Internet Files\Virtualized\{system drive letter}\Users\{username}
I hope to update more this as I dive further into updating my plugin and making it work in both XP and Vista.
