Compatibility windows 7 test

In general, download , install, and launch PC Health Check software on your computer. Then, in its main interface, click the Check now button on the upper part. Within a few seconds, it will give you the result of the compatibility checking and tell you whether the current condition of your machine is able to run Windows 11 or not.

The following are some examples and corresponding solutions for incompatible PC hardware health check. While this PC doesn't meet the system requirements to run Windows 11, you'll keep getting Windows 10 updates. According to the minimum system requirements in below part, you need a bit processor running at 1 GHz or faster with 2 or more cores to run Windows Windows 7 is about to launch. For new Wndows 7 users it might be interesting to find out if your hardware will be supported by Windows 7.

As a rule of thumb, you can say that everything that worked on Vista will also work on Windows 7. This site allows you to quickly find out what will run on your system and what not. OpenDirectoryAcl The problem is indicated by an error message that states that you do not have the appropriate permissions to access the application. The fix reduces the security privilege levels on a specified set of files and folders. The performance issues are visible in certain low-end cards at certain resolutions where the x buffer is scaled to fit the display resolution.

PreInstallDriver The fix preinstalls drivers for applications that would otherwise try to install or start drivers during the initial start process. ProcessPerfData The problem is indicated by an Unhandled Exception error message because the application tried to read the process performance data registry value to determine if another instance of the application is running.

The fix handles the failure case by passing a fake process performance data registry key, so that the application perceives that it is the only instance running. Note: This issue seems to occur most frequently with. NET applications. PromoteDAM The fix registers an application for power state change notifications. PropagateProcessHistory The problem occurs when an application incorrectly fails to apply an application fix.

ProtectedAdminCheck The problem occurs when an application fails to run because of incorrect Protected Administrator permissions. The fix addresses the issues that occur when applications use non-standard Administrator checks, thereby generating false positives for user accounts that are being run as Protected Administrators.

In this case, the associated SID exists, but it is set as deny-only. RedirectCRTTempFile The fix intercepts failing CRT calls that try to create a temporary file at the root of the volume, thereby redirecting the calls to a temporary file in the user's temporary directory.

The fix intercepts the CoCreateInstance call for the missing filter and then redirects it to a supported version. RedirectShortcut The problem occurs when an application cannot be accessed by its shortcut, or application shortcuts are not removed during the application uninstallation process. The fix redirects all of the shortcuts created during the application setup to appear according to a specified path. Desktop or Quick Launch shortcuts: You must manually place the shortcuts on the individual user's desktop or Quick Launch bar.

This issue occurs because of UAC restrictions: specifically, when an application setup runs by using elevated privileges and stores the shortcuts according to the elevated user's context. In this situation, a restricted user cannot access the shortcuts.

You cannot apply this fix to an. RelaunchElevated The problem occurs when installers, uninstallers, or updaters fail when they are started from a host application. The fix enables a child. The fix retries the OpenService API call and verifies that the user has Administrator rights, is not a Protected Administrator, and by using read-only access.

Applications can test for the existence of a service by calling the OpenService API but some applications ask for all access when making this check. This fix retries the call but only asking for read-only access. The fix enables the application to run by using elevated privileges.

The fix is the equivalent of specifying requireAdministrator in an application manifest. The fix enables the application to run by using the highest available permissions. This is the equivalent of specifying highestAvailable in an application manifest. RunAsInvoker The problem occurs when an application is not detected as requiring elevation. The fix enables the application to run by using the privileges that are associated with the creation process, without requiring elevation.

This is the equivalent of specifying asInvoker in an application manifest. SessionShim The fix intercepts API calls from applications that are trying to interact with services that are running in another session, by using the terminal service name prefix Global or Local as the parameter. At the command prompt, you can supply a list of objects to modify, separating the values by a double backslash.

Or, you can choose not to include any parameters, so that all of the objects are modified. Therefore, applications that require access to Session 0 automatically fail. SetProtocolHandler The fix registers an application as a protocol handler. You can control this fix further by typing the following command at the command prompt: Client;Protocol;App Where the Client is the name of the email protocol, Protocol is mailto, and App is the name of the application.

Note: Only the mail client and the mailto protocol are supported. You can separate multiple clients by using a backslash. SetupCommitFileQueueIgnoreWow The problem occurs when a bit setup program fails to install because it requires bit drivers. The fixdisables the Wow64 file system that is used by the bit editions of Windows, to prevent bit applications from accessing bit file systems during the application setup.

ShimViaEAT The problem occurs when an application fails, even after applying acompatibility fix that is known to fix an issue. Applications that use unicows. The fixapplies the specified compatibility fixes by modifying the export table and by nullifying the use of module inclusion and exclusion.

ShowWindowIE The problem occurs when a web application experiences navigation and display issues because of the tabbing feature. The fixintercepts the ShowWindow API call to address the issues that can occur when a web application determines that it is in a child window. Sonique2 The application uses an invalid window style, which breaks in DWM. This fix replaces the window style with a valid value.

SpecificInstaller The problem occurs when an application installation file fails to be picked up by the GenericInstaller function. The fixflags the application as being an installer file for example, setup.

SpecificNonInstaller The problem occurs when an application that is not an installer and has sufficient privileges generates a false positive from the GenericInstaller function.

The fixflags the application to exclude it from detection by the GenericInstaller function. This fix resolves the issue. UIPIEnableCustomMsgs The problem occurs when an application does not properly communicate with other processes because customized Windows messages are not delivered. The fixenables customized Windows messages to pass through to the current process from a lower Desktop integrity level. This fix is the equivalent of calling the RegisterWindowMessage function, followed by the ChangeWindowMessageFilter function in the code.

You can control this fix further by typing the following command at the command prompt: MessageString1 MessageString2 Where MessageString1 and MessageString2 reflect the message strings that can pass. Note: Multiple message strings must be separated by spaces. UIPIEnableStandardMsgs The problem occurs when an application does not communicate properly with other processes because standard Windows messages are not delivered. The fixenables standard Windows messages to pass through to the current process from a lower Desktop integrity level.

This fix is the equivalent of calling the ChangeWindowMessageFilter function in the code. You can control this fix further by typing the following command at the command prompt: Where reflects the first message ID, reflects the second message ID, and reflects the third message ID that can pass. Note: Multiple messages can be separated by spaces. VirtualizeDeleteFileLayer The fix virtualizes DeleteFile operations for applications that try to delete protected files.

VirtualRegistry The problem is indicated when a Component failed to be located error message displays when an application is started. The fixenables the registry functions to allow for virtualization, redirection, expansion values, version spoofing, the simulation of performance data counters, and so on.

For more detailed information about this application fix, see Using the VirtualRegistry Fix. VirtualizeDeleteFile The problem occurs when several error messages display and the application cannot delete files. Windows File Protection is a new feature that prevents applications from replacing system files.

This feature verifies that protected system files are the correct Microsoft version. If a file was replaced with an incorrect version, Windows restores the correct version. Robust heap checking: Windows includes several performance enhancements in the heap manager. Applications that did not use heap management correctly before might now have their memory management problems exposed.

Common problems include using memory after it has been freed and assuming that a memory does not move when it is reallocated to a smaller size. Enumeration of hardware devices: Changes in the list of supported hardware devices might cause problems for applications that use devices that are no longer supported. Enumeration of fonts: The list of fonts has changed. Because registry keys have been added to support internationalization, some applications might see multiple displays of fonts.

Changed registry keys: Some registry keys have been moved or deleted. Applications that write to the application programming interface API should not experience problems, but they can have problems if they write directly to the registry. Version checking: Application installation programs that check versions incorrectly can have problems. Check for the version your application requires or later, unless your application is dependent on a specific operating system or version.

Applications that use file filters, such as anti-virus programs, may lose significant functionality in Windows or later. When you encounter application compatibility problems, you need to prioritize them and then assign someone to resolve them.

You should have a plan for how to assign problems. Assigning the appropriate personnel to research and resolve problems is critical to the success of your application testing. Problem resolution might encompass a wide variety of activities, such as the following:.

As you research the cause of a problem, consider various approaches to determine the most effective solution. For example, you might choose to:. Always be sure that a problem does not occur on your current platform before researching it as a Windows compatibility issue.

Some of the available resources for researching Windows compatibility issues are:. Appendix E provides the specific location where can you obtain the specification. This guide include valuable information about diagnosing compatibility problems. Directory of Windows applications, which includes support information and links to vendor Web sites. Summary One of the primary tasks in preparing for testing is to write a test plan. More Information When you develop a test plan for testing application compatibility with Windows, include the following: Scope: What priority levels you address during testing?

Methodology: Who does the testing involve? Criteria for pass-fail: What determines if an application passes or fails? Schedule: How do you plan to complete the testing by the scheduled date? Establishing the Testing Scope If your organization uses many applications, you may not have time to test all of them as thoroughly as you would like. Defining the Testing Methodology When you plan the methodology, consider the following: Where will the testing take place?

Who will perform the tests? How will you communicate with and involve participants? How will you schedule the testing? How will you manage application problems?

Identifying Resource Requirements As you plan for application compatibility testing, keep in mind the future state of your computing environment.

Defining Pass-Fail Criteria Define a procedure for testers to know when and where they are to log application problems and issues that you want to resolve. To define the criteria for pass and fail, consider issues such as the following: How significant is the problem?

Does it affect a critical function or a peripheral one? How likely is someone to encounter the problem? Is there a way to circumvent the problem?
