Checking file signature on Windows

The sysinternals suite provides the sigcheck.exe tool which is useful to verify the integrity of a file:

Recently I had a strange issue on my Windows 10 tablet.   The Windows firewall asked me whether I trusted wuapihost.exe to communicate out on my private or public network.  This is an odd issue and is most likely a bug.  Information online is currently not very helpful.

The best thing I could do is simply verify the integrity and signature of the file by using sigcheck.exe

I used it to check both the MD5 hash and the certificate signature.  The tool also offers an option to have it uploaded and checked by "www.virustotal.com"; a subsidiary of Google.

The results of the tool:

c:\windows\system32\wuapihost.exe:
