I've had this error for months now and I've just ignored it, but recently I reformatted my drive and started over with Windows and the error persists. I believe I've searched for solutions in the past and didn't find anything, so I was curious if there's a known fix for this:

Houdini has detected a new version of Windows, and may run slower as a result.
Contact SideFX about getting an upgrade to Houdini to address this issue.

-> Fail: _msize (ucrtbase.dll), byte pattern: <E9AF0A0100CCCCCCCCCCCC>
END_INFO

I'm running Windows 11 but since Windows 10 is EOL now, I assume SideFX supports it. I'm tried setting the variable to 0 but then I get another message warning me about slow downs with something else (sorry I forget what it was).

Any thoughts?

Thanks,

Paul

Please use the Support > Report a Bug/RFE link above and include the exact output as well as exact Windows version (run winver command). These come up occasionally with Windows Updates.

Have you solved this issue? I am facing the same issue after I updated to windows 11 24H2.

It was solved at the time, but it looks like the new Windows 11 update has now changed it yet again.
