Windows 10 taking a long time to boot with Hyper-V enabled

So i noticed my PC was taking like 40 seconds to boot when it previously was taking way less.  i thought it might be a BIOS problem but turns out it was Hyper-V, which is needed for Virtualization in windows.

Turn it off with add remove;

Source: Microsoft

To turn off Hyper-V with powershell;

HackTheBox: FFUF not showing file sizes in Kali console

Was working my way through the exercises on hackthebox.com and every FFUF scan was saying the file size as 0.

 

 

 

 

 

Turns out it was Bitdefender’ “Online Threat Protection” ->”Network threat protection”.

This blocks the filesize of FFUF results so the will come out as 0 if you are connected using VirtualBox.

 

Linux Parrot-OS How to switch window control box to right side

ParrotOS is another nice Security based Debian Linux Distro i found the other week but if your a windows user the placement of the “minimise and maximise” windows buttons is very frustating as there on the left side.

Open the menu and select “Control Center”. Then from the “Look and feel” section select “MATE Tweak” and then from the left side pick “Windows”.

Change the “Window control placement” from left to right.

Parrot Security (ParrotOS, Parrot) is a Free and Open source GNU/Linux distribution based on Debian Stable designed for security experts, developers and privacy aware people.

It includes a full portable arsenal for IT security and digital forensics operations. It also includes everything you need to develop your own programs or protect your privacy while surfing the net.

Parrot is available in three main editions, SecurityHome and Architect Edition, even as Virtual Machine (Virtual Box, Parallels and VMware), on Raspberry Pi and also on Docker.

From version 5.0 LTS, support for ARM platforms (arm64 and armhf) is back, and some images are also available for boards like Raspberry Pi.

The operating system ships by default with MATE Desktop Environment, but it is possible to install others DEs.

Windows 10 Wont enter sleep mode with Logitech Extreme 3D Pro Joystick plugged in

 

 

 

 

 

 


Windows 10 Wont enter sleep mode with Logitech Extreme 3D Pro Joystick plugged in.

I ran into this problem a while back as no matter what i did my PC would enter sleep mode.  i tried everything;

  • bios settings
  • windows power saver settings
  • driver updates

Turns out it was due to having the Logitech Extreme 3D Pro Joystick plugged in which i might add is a superb Joystick for Flight Simulator 2020.

Geforce Experience Bug:

Turned out, there is a bug in nVIDIA experience, down in the Windows driver level that would prevent the system from being idle, if you have a joystick plugged in (the article goes a bit deeper into details, it is very interesting if you are a software development related kind of person).

TL:DR , if you have nVIDIA GPU + nVIDIA GeForce Experience installed + have any kind of joystick plugged into the system , Windows won’t be able to sleep/turn screen off automatically until either:

  1. You turn off nVIDIA GeForce Experience in-game overlay.

  2. You unplug ALL joysticks off your system.

PSA: if GeForce Experience is enabled and joysticks are plugged in, Windows can’t automatically turn off screen / go to sleep. This is critical if you are using an OLED screen for your simpit.

Windows 10 send to menu Tweak

The send to menu is located below in windows explorer. Press Windows Key + R to get to the Run dialog Window and enter “shell:sendto”

You can add shortcuts to folders to this location by placing them inside this folder;

C:\Users\<your windows username>\AppData\Roaming\Microsoft\Windows\SendTo

Removing the list of Drives from the sendto menu requires a Registry tweak;

This is one of the most annoying things aboutr the sendto menu as it will list the drives on your system which most of the time isnt needed.

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer]
"NoDrivesInSendToMenu"=dword:00000001

Windows 10 1903 freezes PC – Fix Found

Microsoft did it again, released another f***king update for Windows 10 that broke things. This is the second or third time this has happened now.

This time the problem is similar again to one i had just solved a while ago where my PC would just freeze randomly.

Again this problem was caused by updating Windows 10 to 1809 which i only did a few months ago due to all the issues that update had.

This fucking update is a disaster and i have not been able to roll back to 1809 yet and i still down know whats causing the problem. All the evidence points to the Windows 1903 update.

The problem:
Only seems to occur when the PC is either idle or watching youtube or netflix.

Windows 10 Reliability:

  • Disable AppXsvc using Registry Editor
  • USB 3.0 – front side of PC disabled
  • Installed dot.net 3.5
