What is msdtc.exe?

The genuine msdtc.exe file is a software component of Microsoft Distributed Transaction Coordinator by Microsoft Corporation.
"Msdtc.exe" is the "Console Program" or chief executable object in Microsoft's Distributed Transaction Coordinator (DTC), a background service included in Windows since WinXP SP2 and Windows Server 2003 SP1. Residing in "C:\Windows\System32", along with at least eight Dynamic Link Library (DLL) files also beginning with "msdtc...", and not removable, it enables the applications or databases (including SQL) or other resource managers on a Windows server or PC to use and update transaction-protected resources contained on that system or distributed across a network. What it "coordinates" is the computer's interaction with Microsoft's COM+ system, an enhancement of the Component Object Model which directs the actions of the DTC. "Transaction protection" is ensuring that multiple files or databases involved in a complex operation are not permanently updated unless the entire operation completely succeeds; if one part fails or takes too long to succeed, no changes related to it are retained.

Best practices for resolving msdtc issues

A clean and tidy computer is the key requirement for avoiding problems with msdtc. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
