The genuine SMSvcHost.exe file is a software component of Microsoft .NET Framework by Microsoft Corporation. "SMSvcHost.exe" is part of the Windows .NET Framework, and a very specific part of it concerning "net.tcp// protocol". Known as the "Net.TCP Port Sharing Service", found in "C:\Windows\Microsoft.NET\Framework\v3.0", it has been available since .NET Framework 3.0, formerly termed WinFX, was introduced in 2006, including the Windows Communication Foundation (WCF). It allows managed-code applications running under .NET's Common Language Runtime (CLR) to share ports used for "net.tcp//" protocol, which in turn gives WCF-specific applications a high-performance way to communicate with each other across networks where interaction with non-WCF/non-CLR software is judged less important. It can only be uninstalled by uninstalling the entire .NET Framework. Microsoft Corporation was founded in April 1975 by Paul Allen and Bill Gates. Headquartered in Redmond, Washington, USA, a suburb of Seattle, in terms of worldwide revenue in 2016 it had become the world's largest software maker.

smsvchost.exe is a SMSvcHost.exe from Microsoft Corporation belonging to Microsoft® .NET Framework Ron
Is not a virus, nor does it cause viruses, but it can significantly slow down a computer with its high CPU usage percent. Just like any windows application, it can be duplicated or even altered in a an attack on your computer. It might even be highly targeted, given its runtime percentages. If computer is slow, go to task manager processes and end it. This should speed up gaming ability. If not, check for other high CPU usage, and stop it if you can (if not important to task you are doing) and scan for viruses. Jodi Campbell
.Smsvchost.exe with description SMSvcHost.exe is a process file from company Microsoft Corporation belonging to product Microsoft® .NET Framework. Abidin-G.Antep (further information)
It freezes my computer and i have to end the process. Joe
This issue is not so much whether the file itself is safe. Overnight my ISP decided to "enhance" my PC with a number of new autoloads to push pop-up messages to me and monitor my activity. This was one of the services that was set to start automatically at boot time, along with three or four others (so far--I keep discovering new ones). So the way my ISP is using it is very spammy, but the file itself is not. BB
After installing something off the internet, its cpu usage shot up to almost 50%
lately it seems to freeze my pc during gaming, I close the process and it unfreezes. Lots of processor usage as well when its open. DangerousDan

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 executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command.
