1. WCL312: Standard User Desktops with Windows Vista User Account Control (UAC) (WCL312) Alex Heaton Sr. Product Manager Chris Corio Program Manager

2. Agenda Why be a Standard User How Windows Vista Makes it Easy Standard users can do more Application Compatibility Application and Driver Deployment Q&A

3. Microsoft Confidential User Account Control Challenges Windows Vista Solution Easier to Run as Standard User Users can do more on their own Change time zone, power settings, VPN, and more Install approved devices Admin commands clearly marked Higher application compatibility File and registry virtualization Greater Protection for Admins Software runs with lower privileges by default Administrator provides consent before elevation Most users run with full administrator privileges all the time At risk from malware Can’t manage desktops or enforce policy Expensive to support Difficult to run a standard user User can’t perform many tasks Many applications don’t run

4. Elevation Model Administrator Privileges Standard User Privileges (Default) Administrator Account Standard User Account Ways to Request Elevation Application marking Setup detection Compatibility fix (shim) Compatibility assistant Run as administrator

5. Total Cost Of Ownership Gartner found: Use Best Practices to Reduce Desktop PC TCO, 2005-2006 Update 8 December 2005, Gartner, Inc. “…a locked and well-managed PC can save 40%.” “Fewer PCs will need a dispatched technician to try to remove a worm or recover or re-image a damaged system.” “All of that also means less end-user downtime and higher user productivity.” “The ‘locked and well managed’ profile assumes liberal use of tools, technology and processes for managing PCs...”

8. Standard Users Can Do More View system clock and calendar Change time zone Configure secure wireless (WEP/WPA) connection Change power management settings Create and configure a Virtual Private Network connection Add printers and other devices that have the required drivers installed or allowed by IT policy Install approved ActiveX controls Disk defragmentation is a scheduled background process Shield icon consistently marks what actions a standard user can and cannot do

10. Application Compatibility Initiatives Technologies added to Windows Vista to help applications run as a Standard User Application Compatibility Toolkit provided to help inventory and fix applications within environments. ACT 5.0 Release Candidate currently available Application Compatibility Factory available for outsourcing application compatibility and mitigation.

11. Helping Legacy Applications Run as Standard User Many applications would run fine as standard user, but they needlessly store data in HKLM\Software or %ProgramFiles% They use these locations for per-user data, not global data These locations are system-global and so only writeable by administrators It’s always worked because Windows users have always been administrators The solution: help them through virtualization Modifications of most system-global locations go to per-user areas Reads generally go to the per-user location and fall back to the global location

12. Virtualized Files Redirected file system locations: %ProgramFiles% (\Program Files) %AllUsersProfile% (\ProgramData – what was \Documents and Settings\All Users) %SystemRoot% (\Windows) %SystemRoot%\System32 (\Windows\System32) Exceptions: Files that have executable extensions (.exe,.bat,.vbs,.scr, etc) Prevents masking of system executables for servicing and security Exceptions can be added in HKLM\System\CurrentControlSet\Services\Luafv\Parameters \ExcludedExtensionsAdd Per-user virtual root: %UserProfile%\AppData\Local\VirtualStore Note: Virtual files do not roam with Roaming Profiles

13. File Virtualization Implementation File system virtualization is implemented in a file system filter driver, luafv.sys Luafv.sys Ntfs.sys Legacy Application User Mode Kernel Mode \Windows\App.ini \Users\ \AppData\Local\ VirtualStore\Windows\App.ini Vista Application \Windows\App.ini Access Denied

14. Registry Virtualization Redirected locations: HKLM\Software Exceptions: HKLM\Software\Microsoft\Windows HMLM\Software\Microsoft\Windows NT Other subkeys under Microsoft Per-user virtual root: HKEY_CURRENT_USER\Software\Classes\VirtualStore

15. Solving Application-Specific Issues Some applications have to be helped in other ways to run as Standard User If an application is broken ask the vendor for a fix!! Isolate to standard user compatibility issue Common application issues include: Unnecessary Administrator checks Registering a COM object to HKLM Writing to file or registry locations that are not virtualized Aaron Margosis highlights how to fix these problems in his blog: http://blogs.msdn.com/aaron_margosis/

16. Application Compatibility Toolkit Customer Target Medium/Large Businesses and Large Enterprises Mission A lifecycle management tool that assists in identifying and managing your overall application/device/computer portfolio, reducing the cost and time involved in resolving application compatibility issues, and helping you quickly deploy Windows Vista and Windows Updates.

21. Application and Driver Deployment Problem: Deploying protected machine-wide binaries requires Administrator privileges. Windows Vista Technologies for facilitating deployment: Group Policy Software Installation Device Management Infrastructure ActiveX Installer Service

22. Group Policy Software Installation Method for deploying MSIs within an enterprise MSIs can be assigned to users or groups using Group Policy On Demand installation through advertisement. Policy consists of product information being published in both AD and GP. Enterprises must create an inventory of their applications packaged as MSIs.

23. Managing Device Driver Installation Problem: In enterprises, Standard Users cannot install device drivers but need network printers. Device Management Infrastructure introduced in Windows Vista Configurable by Group Policy Allows Standard Users to install drivers Hardware-first install initiates automatic search for drivers

24. Device Driver Installation Policy Device Management Infrastructure policy is based on the driver location, signature, and device class guid. The Driver Store is a trusted cache of drivers on client machines Dynamic and updatable Windows Vista installs these trusted drivers as needed Device Drivers must be signed by a certificate in the Enterprise Trusted Publishers store. Device class must be enabled for Standard User installation using Group Policy in Driver Installation ADM.

25. ActiveX Installer Service Service built into Windows Vista because of extensive customer feedback. ActiveX controls are designed to install per-machine This requires administrator privileges. Packaging ActiveX controls into MSIs is expensive. Many enterprises do not have a full inventory of the controls that are used in their environment. No good pull-based solution for MSI deployment

26. ActiveX Installer Service is an optional Windows Component included in Ultimate, Enterprise(N), and Business SKUs. Manually enabling the service Control Panel ->Programs->Turn Windows Features on or off. Check the ActiveX Installer Service Service can be enabled within image Policy is configured using an Administrative Template in Group Policy. Enabling the ActiveX Installer Service

27. ActiveX Installer Service: Policy Installation Policy based on Host URL and signature of content Host defined by URL http or https (recommended) Cab file signature can be checked against enterprise Trusted Publishers store. ActiveX Controls can be deployed from a central server using CodeBaseSearch path. Attempt to install ActiveX control is audited.
