64-bit for Internet Explorer 10

On Windows 7 I’ve always chosen to open Internet Explorer (64-bit) rather than the standard 32-bit version. This is in the hope that because the former is both older and more popular it might be more subject to vulnerabilities. Whether that it true or not I don’t know, but it’s worth it right…

Note that there is some downsides 64-bit. For example in SkyDrive trying to open an office (Word/Excel) file for edit locally fails (maybe because the target apps are 32-bit).

Anyway, a while back, don’t know quite when…maybe with the upgrade to MSIE 10 that ability was lost. I still use the Internet Explorer (64-bit) shortcut but the MSIE copy that opens is 32-bit. How do I know? Well I use Aaron Margolis’s PrivBar which shows that amongst other things. The screenshot below shows it reporting “32-bit” along with “Low IL”, and my userid.

MSIE PrivBar shows 32-bit

I’ve never got around to investigating that until now. But after some googling I think I’ve found the answer…

In short set “Enable Enhanced Protected Mode“, reboot and then you’ll find 64-bit mode is back.

MSIE10 Opts Advanced e.g. EnhancedPM   MSIE PrivBar shows 64-bit after EPM

I’ve only been running in this mode for a little while but it seems good.

For more details see the following articles. The search returned the first article and based on that I found the Microsoft articles; the first is general, the second’s more about the internals, and the last is aimed at the developer of plugins.

BlueZ sdptool usage notes

I’ve been doing work on Bluetooth support on BlueZ on Linux.  For instance I’ve added support for that platform to the 32feet.NET library, see on Linux  I’ve also been reading Hacking Exposed: Wireless by Cache et al (Amazon UK Kindle edition) which discusses the use of the sdptool utility.  Finally I was also also playing with BlueZ’s XML format for SDP records.

In using sdptool it was not clear to me what the various commands did; what is “search” versus “browse” for instance.  The man page for the tool is fairly basic and says itself: “Documentation needs improving.”

So here’s my notes on usage:


  • search
    • Usage: search [–bdaddr <bdaddr>] { –tree | –raw | –xml } <service_class_id>
    • “Queries for records with the specified Service Class.  Either on one specified device, or on all devices in range if no device address is specified.”
    • “The Service Class Id can be specified by name, or as a number (UUID16/32 e.g. 0x1101 for SPP).  See below [in the manpage] for the known names.”
  • browse
    • Usage: browse {–tree | –raw | –xml } { –uuid <service_class_id_number> |-l2cap} [<bdaddr>]
    • “Queries for records that are member of the Public Browse Group, or by specified service class id.”
    • “A device address can be specified as the last parameter, otherwise the query is done on all devices in range,”
    •  “Or, with ‘–l2cap’ queries all records containing the L2CAP Service Class Id.  Connectable services all generally use the L2CAP protocol so will be returned by this query.”
    • “Or, with ‘–uuid <service_class_id_number>’ queries all records containing the specified UUID16, which may be in hex or decimal format, e.g. 0x0100 for L2CAP, 0x1101 for SPP, or 3 for RFCOMM.”
    •  “(This command is largely equivalent to calling “search” with the specified UUID in the three cases being respectively: PUBLIC_BROWSE_GROUP (0x1002), <NUM>, L2CAP (0x0100).  And passing the optional address as the –bdaddr parameter there).
  • records
    • Usage: records { –tree | –raw | –xml } <bdaddr>
    • “Tries to find all record by querying by Service Record Handle number.”
    • “Various ranges of handle numbers are searched to match the ranges used by known device types.”
    • “The device address is not optional.”
  • get
    • Usage: get [–bdaddr <bdaddr>] { –tree | –raw | –xml } <record_handle>
    • Queries for the service with the specified Service Record Handle number.
    • Either on the local device, or on all devices in range if no device address is specified.
  • del
    • Usage: del <record_handle>
    • Deletes the service on the local device with the specified Service Record Handle number.
    • BTW the handle for each record is displayed in each output e.g. “Service RecHandle: 0x1000b”.

There are also three more commands for adding a new record or elements to an existing local record (add, setattr, setseq).  I have not used those commands.  Maybe at a later date…

Bluetooth device address format: XX:XX:XX:XX:XX:XX.  So that’s six hexadecimal digit-pairs colon separated (i.e. length 17).  If a different format is entered odd things happen.  Something for further investigation…

Record output format: Four types ‘normal’, tree, raw and xml.  Normal displays only the known attributes and in a simple format, tree displays all the attributes with names given to known sub-elements, raw also displays the whole tree but with all element types given, and xml encodes the tree as XML.

I am happy for this documentation to be added to the man page etc.  Just add attribution please (“Alan J. McFarlane“).
