The Program Compatibility troubleshooter can help resolve many application issues . Using the troubleshooter, you can test various compatibility options on various programs to find the setting that allows the programs to run under Windows 7 . To start the Program Compat-

ibility troubleshooter, click Start, Control Panel, Programs, and then Run Programs Made For Previous Versions Of Windows . The Program Compatibility troubleshooter starts as shown in Figure 5-2 . To begin the application compatibility diagnostic process, click Next .

You can use the ACT for anything more than a few one-off, simple mitigations . It helps you create an inventory of the applications in your organization . It also helps identify which applications are compatible with Windows 7 and which applications require further testing . The following are some of the major components of the ACT solution:

Application Compatibility Manager A tool that enables you to collect and analyze your data so that you can identify any issues prior to deploying a new operating system or a Windows update in your organization . You use this program heavily during the initial phases of an application migration project . You should consider this tool as the primary user interface for the ACT . Application Compatibility Toolkit Data Collector The Application Compatibility Toolkit Data Collector is distributed to each computer and scans by using compatibility evaluators . Data is collected and stored in the central compatibility database .

Setup Analysis Tool (SAT) Automates the running of application installations while monitoring the actions taken by each application s installer . Standard User Analyzer (SUA) Determines the possible issues for applications running as a standard user in Windows 7 .

The ACT is indispensable for testing a wide variety of applications across a variety of computers and operating systems within your organization, using solutions based on a common pool of application fixes provided by vendors and users . You can use the ACT tools separately or together, based on your organization s needs . Some tools, such as the SAT and SUA, are intended for developers to enable application remediation and are not necessarily used in the scanning and mitigation process .

In some instances, such as when standard application mitigation strategies fail, virtualization technologies might be appropriate . For example, you can use Windows XP Mode as a safety net for applications that aren t compatible with Windows 7 . The Windows XP Mode environment is available for Windows 7 Enterprise, Professional, and Ultimate Edition operating systems . Using Windows XP Mode, users can run a Windows XP virtual machine on a computer that is running Windows 7 . This way, you can proceed with your Windows 7 deployment rather than delay because of application incompatibility . Your organization can take full advantage of the new features and capabilities in Windows 7 and still provide user access to earlier versions of mission-critical applications . In addition, the organization can realize a return on the investment of upgrading to Windows 7 faster than it would by implementing other shortterm application compatibility solutions . Windows XP Mode requires Windows Virtual PC, which is an update that you apply to Windows 7 Enterprise, Professional, and Ultimate Editions . Windows Virtual PC provides a time-saving and cost-saving solution anywhere users must run multiple operating systems (x86 operating systems only) and is an excellent short-term solution for mitigating application compatibility issues; it allows you to continue with Windows 7 deployment . However, you should consider selecting a longer-term solution . Note that Windows Virtual PC requires a CPU with the Intel Virtualization Technology or AMD-V feature turned on . This feature must be enabled in the system BIOS . Installing Windows XP Mode is easy . You must first install Windows Virtual PC and then install Windows XP Mode . You can perform both tasks from the Windows Virtual PC Web site at http://www.microsoft.com/windows/virtual-pc/download.aspx .
