application waiting on splwow64.exe - but why?

[Azazaz]

Everything was going along just fine and then all the sudden my usually well-behaved project (a C++Builder 10.1 Berlin Update 2 project on Windows 10 with the latest updates as of about an hour ago) started freezing up, and I have been so far unable to trace it in any meaningful way in the debugger.

When I look in the Task Manager and analyze the wait chain, its says it is waiting on "splwow64.exe" -- so I searched online and apparently this is fairly common, but I've found no solutions.

(Ending the process as some have suggested doesn't help.)

It is my understanding this is a print driver? Don't know why it would be active or why my application would be waiting on it as it is not trying to print anything, i.e., there's nothing in my code right now that is trying to print, although there could be some reference in WPTools, I guess.

Anyhow, I am hoping someone here might be able to give me a clue about what to look for? Thx.

Try this

basically you need to edit the registry to adjust the timeout. The windows cumulative update probably changed the timeout to two minutes. that process is used to convert 32 bit jobs into 64 bit jobs.

Thanks, Scott. I'll give it a try.

But it didn't help.

Looks like I'm going to have to dive a lot deeper into this.

Thanks, though.
