dllhost.exe(COM SURROGATE) Auto minimize to desktop every game

[PuPpEt]

It happens only with Steam opened, every game autominimize to desktop for a nanosecond instantly.
I think i have found the culprit using ProcessExplorer:
in that nanosecond that it auto-minimize, i have a little usage spike in the I/O graph and is the dllhost.exe, and it seems the thumbcache.dll... but i'm not sure.
What can i do to narrow down the problem?

This could be due to a malicious process from my research. Below I have attached links Microsoft and to the Malwarebytes forums to allow you to fix this issue. Please try the suggestions at Microsoft's help board first.

It doesn't help, cause that's the first thing i did before creating the thread, checking for rootkits viruses.
The PC is clean, the problem could be the Windows 10 Thumbnail cache but i'm not sure...
I have excluded Steam install paths in the 2 antivirus i use (kaspersky + malwarebytes) and in Windows Defender and apparently it doesn't autominimize anymore, but i need further intensive testing...
