Anybody knows if there are any logs or diagnostics when you turn on Core Isolation / Memory Integrity, and on the next reboot Windows does a double reboot and it is (still) switched off.

Or how to...

DNS is not changed, it's just what it gets from DHCP.

I did toggle a few options in Windows Update settings, but apart from delay for 7 days (or a specific day), some things don't stick. For...

I don't, and have never used a use a VPN on this PC.

I've checked that proxy settings. And it's not set to any specific proxy. The automatic checkbox on or off doesn't change the windows update...

I've ran sfc and DISM a couple of time already. Though I've used `Repair-WindowsImage -Online -RestoreHealth`. Which is the Powershell equivalent to cmd's DISM.

By now none of them give any...

How to get Windows Update working again on this system ?

Under Windows 10 21H1 I'm getting this message in Settings > Update & Security:

"We couldn't connect to the update service. We'll try...

Just in case it helps anybody. I was getting SECURE_KERNEL_ERROR bluescreens (BSOD). Which went away after updating Intel Wi-Fi drivers:

In case Windows had trouble removing WSL1 files named "aux.h" (AUX is a reserved word since MS DOS). You can remove those files under bash running as Administator.

Eg:

Open CMD as administrator...

So this ?

reg delete HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E967-E325-11CE-BFC1-08002BE10318}\ /v lowerFilters

Edit: I did this, and the driver file is no longer...

Just a little remark, if you just do

reg delete HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E967-E325-11CE-BFC1-08002BE10318}

Then you system won't boot, because it cannot...

Is somebody maintaining a list of things that stop Windows from booting when the Windows Hypervisor is installed ?

Beyond the obvious "CPU does not have virtualization, or the BIOS doesn't have...

It is probably listed at the bottom of `msinfo32`.

Just a heads-up but the new guide from Microsoft (the same page that you link to) now also says to set File Blocking Level to High (or High+), and to increase the time it waits for the cloud analysis...

The sort of slowdowns that you might be seeing with this turned on have more to do with I/O, so disk, network, display. Memory benchmarks shouldn't slow down very much, maybe memory allocations...

A sideways answer is that VMware still has support for "binary translation" for its 32bit guests. This is the way that virtualization used to work before VT-x/AMD-v. On Intel CPU's where VT-x was...

Well, it was fun figuring it out. And the system would hang every 1-2 months. So tightening up the drivers should only improve things.

Hmm, I managed to enable 'Memory Integrity' on a Sony VAIO VPC-CA2S1E from 2011, with the 'on' register file from the topic start (Windows Defender would bail out muttering about incompatibilities...

Just because it's a successor doesn't mean that the driver developers of this new laptop paid attention to non-enforced soft requirements. The 3520 is currently not on the list. So unless you have a...

HP has a similar-ish page at...

In principle you can check compatibility using the 'Download Device Guard and Credential Guard hardware readiness tool'. It is not entirely clear what checks are compulsory to pass for 'Memory...

You need to run `verifier /reset` and reboot afterwards; or open the verifier and choose the reset option in the GUI and reboot (same thing).

The readiness tool keeps the "Code Integrity...

Edit: nonsense old content from 2017.. oops..

Hey thanks, but it seems that the usbfilter.sys filter driver is attached on another level than these devices in the overview. And when you uninstall it through the commandline, you have to break out...

Well, virtualization has impact on I/O performance. Each time something is communicated to/from a driver in a virtualized security domain it has to be packaged and transfered over the security...

Well, this is a Windows 10 Home install, so I can't really test Hyper-V any more than this. I don't remember having any trouble running VMs (under Linux at least) in the past. Everything ought to...

I've disabled the network driver and used DDU to uninstall the nvidia drivers. What remained of third party drivers was usbfilter.sys.

Still a blue screen. So it's either the USB driver, or none...
