Hi everyone, We’re starting a fresh thread for Windows 10 users still impacted by system freezes that started last month following a problematic Microsoft security patch. We have a workaround that may help mitigate the system freeze. Extensive discussions with Zwifters indicate this freeze continu…

Sure, I understand that. I’m not a Windows user, I am Mac only. However, I would imagine there are plenty of Windows users who install the Nvidia driver, essentially “replacing” the default Microsoft video driver. If Windows is using the Nvidia driver and it is not a supported video card, how woul…

It’s a zwift issue, all the versions of Nvidia drivers I’ve tried work fine everywhere except with Zwift hence this workaround until they fix it properly.

No the issue was caused by a Microsoft update. It doesn’t have anything to do with the Nvidia driver version and was not coincidental with a Zwift update. There is no point in trying other Nvidia driver versions. The problem does not affect all apps in the same way.

It’s a zwift issue if I decide go to mywoosh, ic trainer, rouvy etc which don’t seem to be affected Isn’t that what the insider builds are for, the preview channel-beta channel-dev-channel-canary channel

The release of those Microsoft updates was a widespread disaster affecting many applications. I’m sure all of them are trying to work around it if they can, as Zwift is attempting to do with this workaround. I certainly don’t blame you as a consumer for choosing to run whatever works for you. It’s n…

Windows 11, GTX970, all updates installed. Continued hard locking when loading before this, even though your language suggests it’s only impacting Windows 10 users. This fix does allow me to get into the game, we’ll see if it’s stable.

Runs smoothly for me. Thank you. Win10 ESU, KB5075912, NVIDIA GeForce GTX 960M

Windows 10 with Extended Support License (KB5075912) GeForce GTX970. Without debug I have complete freeze on login and has to cut power from PC. With debug it works.

Doesn’t work, still freezes. That has changed that Zwift doesn’t freeze during startup, but after the ride, when saving the ride - which is of course lost.

Do you have Video Screenshots enabled on that device? That is a common reason for failed saves on PCs.
