Controlling block storage devices on USB buses

I haven't seen a lot of talk about this recently but I recall several months or even a year or so ago that this was a hot topic with all of the new USB flash drives hitting the market. I had some conversations with MVPs and members of the product teams about this. At the time, we didn't have any plans to tighten things down and give the ability to block users from writing to these types of devices but with our SP2 security push, lots of plans got changed.

So, the ability to turn USB storage devices in to ReadOnly devices has been implemented in SP2 through a registry setting.

Setting name Location Default value Possible values

WriteProtect

HKEY_LOCAL_MACHINE\System\
CurrentControlSet\Control \StorageDevicePolicies

DWORD=0

0 - Disabled

1 - Enabled

Speaking of SP2...

Many of the new features in SP2 can be easily controlled through Group Policy Settings. The following download is a reference for the Group Policy Settings in SP2. Have a look!

Overview
This spreadsheet lists the full set of Group Policy settings described in Administrative Template (.adm) files that shipped with Windows XP SP2. This includes all policy settings supported on the following operating systems: Microsoft Windows Server™ 2003, Windows XP Professional with SP2 or earlier service packs, and Microsoft Windows 2000 with Service Pack 4 or earlier service packs. The spreadsheet includes separate worksheets for each of the .adm files that shipped in Windows XP SP2 , a consolidated worksheet for easy searching, and an Update History worksheet that lists policy settings that have been added since the Windows Server 2003 operating systems were released. Using column filters, you can easily filter the information in the spreadsheet by operating system, component, or machine/user configuration. You can also search for information by using text or keywords. Note: This page will be updated with the latest .adm files associated with pre-release or beta versions of the Windows operating system.

More time to test Windows XP SP2

As you may or may not know, we have implemented a method that will allow corporations to block their systems from downloading SP2 from either Windows Update or Automatic Update. See the following link for details:

http://www.microsoft.com/technet/prodtechnol/winxppro/maintain/sp2aumng.mspx

Originally this mechanism was only going to be in place for 120 days. This has been extended to 240 days or April 12, 2005 in order to allow customers more time for deployment testing.

The “mechanism” in question is a registry setting that WU/AU looks for. After the 240 period ends, WU/AU will no longer check for that setting.
