Everything is enabled. I also enabled the option to receive test tasks.

What's not enabled is the run native option.

So why i'm not receiving new tasks on Windows? It's months already. Not something recent.

You are not alone.
Theory and CMS are possible.
Your prefs must be set without native.
Windows running only Virtualbox-Tasks and sixtrack without Virtualbox.

You computer details show this:
Virtualbox (7.0.10) installed, CPU does not have hardware virtualization support



This usually means either:
1.
Virtualization is not enabled in the computer's BIOS.
If it was enabled it may have been disabled again by a Windows update.

2.
VirtualBox can't detect virtualization because it is in use by another hypervisor, in most cases Window's Hyper-V
=> Disable all Hyper-V components

In task manager i see that virtualization is still enabled, while in Windows Features under Hyper-V nothing is enabled.

I'm confused now.

Should i tick everything under Hyper-V then?

It is an issue between Windows and VirtualBox rather than a BOINC issue since BOINC just asks the OS whether virtualization via VirtualBox is available or not.
You may find more information here:
https://learn.microsoft.com/en-us/troubleshoot/windows-client/application-management/virtualization-apps-not-work-with-hyper-v


Be aware:
As long as BOINC can't identify virtualization and reports that at your computer details page you will not get any vbox tasks.

Thank you computezrmle. At least we know that it's not an Hyper-V problem.

Disabling Device Guard and Credential Guard makes me worry so i think i'll just surrender.

It's sad because in the past nothing of this was needed.

Today i found that removing it from control panel/windows features seems not enough
