Introduction

Ever wondered which program has a particular file or directory open? Now you can find out. Process Explorer shows you information about which handles and DLLs processes have opened or loaded.

The Process Explorer display consists of two sub-windows. The top window always shows a list of the currently active processes, including the names of their owning accounts, whereas the information displayed in the bottom window depends on the mode that Process Explorer is in: if it is in handle mode you’ll see the handles that the process selected in the top window has opened; if Process Explorer is in DLL mode you’ll see the DLLs and memory-mapped files that the process has loaded. Process Explorer also has a powerful search capability that will quickly show you which processes have particular handles opened or DLLs loaded.

The unique capabilities of Process Explorer make it useful for tracking down DLL-version problems or handle leaks, and provide insight into the way Windows and applications work.

Note on use of symbols

When you configure the path to DBGHELP.DLL and the symbol path uses the symbol server, the location of DBGHELP.DLL also has to contain the SYMSRV.DLL supporting the server paths used. See SymSrv documentation or more information on how to use symbol servers.

Windows Processor Requirements

This specification details the processors that can be used with Customer Systems that include Windows Products (including Custom Images). Updates to this specification may be released in the future as requirements change.

For each listed edition, Company must use only the processors listed, as specified in the tables below. The requirements below apply whenever the edition below is pre-installed or provided on external media, including as downgrade or down edition software.

For clarity, Company must also meet all processor and other requirements specified in Minimum Hardware Requirements for Windows 10, located at https://msdn.microsoft.com/library/windows/hardware/dn915086(v=vs.85).aspx (or updated URL).

If after the inclusion of a processor series in this specification (“Listed Processor”), a processor becomes commercially available that uses the same naming convention or identifier as a Listed Processor but has additional or different features or functionality (“New Processor”), Company must not use New Processor for Customer Systems without Microsoft’s prior written permission. If Company believes a processor has been omitted from this list, please contact Company’s Microsoft OEM or ODM Account Manager.

The processors listed in the tables below, represent the latest processor generations and models which are supported for the listed Windows Edition. Previous generations of processors and models (indicated by «Up through»), remain supported in addition to the listed processors and models.

Some product editions or edition/processor configurations listed below may have no or limited support. Information on support is available at Microsoft Support Policy (https://support.microsoft.com/lifecycle) and Microsoft Lifecycle FAQ (https://support.microsoft.com/help/18581). For specific hardware support, please refer to your Original Equipment Manufacturer (OEM) provider.
