What is MatsBoot.exe?

The genuine MatsBoot.exe file is a software component of Microsoft Automated Troubleshooting Services by Microsoft Corporation.
"MatsBoot.exe" is a Microsoft process, the Microsoft Automated Troubleshooting Services (MATS) Bootstrapper. MATS is accessed through "Download" buttons in Microsoft Knowledge Base articles about specific problems. It downloads a specific executable troubleshooting package that gathers information pertinent to the Knowledge Base article, uploads it back to Microsoft servers, and sometimes performs operations fixing problems automatically. As part of such packages, "MatsBoot.exe" always installs in a temporary subfolder of "C:\Windows\Temp", named "\RunBoot-Temp_.%URI%}", the Unique Resource Identifier of that one MATS package. Microsoft articles and blogs do not describe its functions but do state that MATS packages test whether PowerShell 1.0 or 2.0 is present, and .NET Framework 2.0 or 3.5, and can install PowerShell 1.0 (but not 2.0) if needed. The Bootstrapper may do that and also proceed to unpack other components. The Microsoft Fix-It Center once used to access MATS was discontinued in favor of the Knowledge Base approach.
