Windows 11 24H2/25H2. issue appears randomly and breaks workflow, very annoying

Answer 1

Hi there,

I totally get how disruptive that freeze can be, especially when everything looks fine, but nothing responds.

What’s happening here is that Windows sometimes struggles to fully wake certain background processes after being idle or locked, usually tied to graphics drivers or how the system handles power states in the latest 24H2/25H2 updates.

Let’s try a few quick things to stabilize it: update your graphics drivers directly from your GPU maker’s site (Intel, AMD, or NVIDIA), turn off hardware acceleration in apps like Teams, Edge, and Office, and disable Fast Startup in your power settings.

If it keeps happening, open Task Manager next time and try restarting Windows Explorer, that can bring it back without a full reboot.

Just to confirm, does it happen only after the screen’s been locked in a while, or also when the system wakes up from sleep?

That’ll help me guide you on the next step.

Regards,
Aron
