All the fixes I've read involve installing this or that or some system restore (which is NOT system recovery.)
HOWEVER "hostprotocol.exe" is more interesting. You could try disabling the indexer. This is all over the web but I see John Rudby tell how at:
http://answers.microsoft.com/en-us/windows/forum/windows8_1-performance/searchprotocolhostexe-using-100-cpu/f0241aac-fcb4-472d-83e5-e9f9f509546a
I'd try that.
But I fear it's the usual malware infection but as you don't want to install anything you may have to muddle along.

Hello Guys,
I get on a computer the "Runtime Error R6016 - Not enough space for thread data"
I looked on Google, not very helpful.
I do not want to install anything to fix the issue and I don't want to restore the computer.
I was wondering if anyone could help me fix the issue without installing any other software.
The computer has Windows 7 and the error message appears with the path to C:\Windows\system32\..hostprotocol.exe or something like this, can't remember for sure.
Thanks in advance!
Nick
