While testing our WEB application using IE10 on Windows 7 operating System, we have found the difference between Windows 7 32 bit and 64 bit operating system because of which we are seeing application behaves differently with respect toexplorer bars.
We are using customized explorer bar.
We have installed our 32 bit application in Windows 7 (64 bit) operating system with IE10.
Problem description
Application installed in Windows 7 64 BIT Operating System.
Multiple users will be created in the machine where application is installed.
We see that whenever a new user(Standard User account) created and logged into the workstation, Explorer bar isNOT loading until weremove the following registry keys.
- Computer->HKEY_CURRENT_USER->Software->Microsoft->Windows->CurrentVersion->Explorer->Discardable->PostSetup->Component Categories->{00021493-0000-0000-C000-000000000046}
- Computer->HKEY_CURRENT_USER->Software->Microsoft->Windows->CurrentVersion->Explorer->Discardable->PostSetup->Component Categories->{00021494-0000-0000-C000-000000000046}
- Computer->HKEY_CURRENT_USER->Software->Microsoft->Windows->CurrentVersion->Explorer->Discardable->PostSetup->Component Categories64->{00021493-0000-0000-C000-000000000046}
- Computer->HKEY_CURRENT_USER->Software->Microsoft->Windows->CurrentVersion->Explorer->Discardable->PostSetup->Component Categories64->{00021494-0000-0000-C000-000000000046}
Application installed in Windows 7 32 BIT Operating System.
We are NOT facing this issue. Application is working as expected. We no need to delete any registry keys.
From the MICROSOFT site, we have understood the reason for this issue is theEnumeration cache.
Following is the reference link

NOTE :
The same setup of our application is working without any issue in Windows 7 32 bit operating system.
Also We observed the same issue in other versions of IE(8 and 9) as well.
Now the question is Enumeration cache happens only in 64 bit version of windows?
Is 32 bit operating system have any different way for the enumeration cache?
