I am brand new to docker with windows. I have installed the Docker toolbox version as my laptop cannot run hyper-v. After the installation of Docker Toolbox (OS is Windows 10 Home) I run Docker Quickstart Terminal and in the console, I see this:
Running pre-create checks...
Error with pre-create check: "This computer doesn't have VT-X/AMD-v enabled. Enabling it in the BIOS is mandatory"
Looks like something went wrong in step ´Checking if machine default exists´... Press any key to continue...
I have opened my BIOS menu to try to change this but I am not presented with an option to do so as if it's hidden. I've no idea how to get around this and other StackOverflow solutions are not fixing my issue.
My Laptop model is an Acer Aspire E1-531.
Any help on enabling the VT-X/AMD-v would be brilliant thanks
You really don't need a new laptop. If the virtualization is disabled, you may enable it while turning on your system.
From: https://amiduos.com/support/knowledge-base/article/enabling-virtualization-technology-in-hp-systems
Turn ON the System
Repeatedly press Esc key at startup.
Press the F10 key for BIOS Setup.
Press the right arrow key to System Configuration tab, Select Virtualization
Technology and then press the Enter key.
Select Enabled and press the Enter key.
Press the F10 key and select Yes and press the Enter key to save changes and Reboot.
Follow this link to see your laptop support VT-X/AMD-v. If not then you have no other choice other than changing your laptop to run hypervisors.

I am using XFCE terminal in Debian linux on Apache Guacamole from MacOS X.
I'm trying to navigate between tabs in the XFCE's terminal using ALT key shortcuts (e.g. ALT+1 and ALT+2) like shown in the screen below:
I've tried every key combination I can think of, plus researched at places like this. But I haven't yet figured out the secret.
How can I issue these ALT- key combinations from my Mac keyboard in Guacamole?
Usually the modifier key ALT on a PC means "alternate" which would translate to Mac's keyboard symbology as Option (on some Macs drawn with a branching-switch icon):
Solution (when Guacamole uses realVNC)
According to realVNC (one of the possible connection protocols by Guacamole) your needed "from Mac to PC" key mapping would be:
Pressing "CmdL" (left Command key on your local Mac) will result in "AltL" (left Alt key on the remote PC/Linux)
Insightful thoughts
When using Guacamole, which probably uses VNC or XRDP protocol to connect your local client (Mac) to the remote server (Linux), the keyboard mapping has to pass 2 layers, from your local hardware/OS (Mac) to browser, over Guacamole/XRDP to the remote-system (Debian with XFCE).
All these layers can interpret the key-events triggered.
Research
Like a user of this XRDP-related forum post from MacRumors (from 2015) explains:
As below link states, Alt key of PC keyboard should be mapped as Option key on OS X. This is what we see on ARD. On XRDP Alt key behaves like Windows key and is mapped to Command key.

Griffon's IT Library blog: XRDP – How To Make your keyboard “special keys” (Alt+Gr, Up,Down,..) working when using XRDP
I've recently swtiched from a Windows work PC to a Mac Book Pro. Most of my development work is done over an RDP connection to a Windows 2012 server.
When doing development work, I use IDE's and other tools that have custom keyboard shortcuts involving the Windows key. For instance, [win]+[backtick] is set to open a console. As long as I was connected to the RDP session in full-screen mode, the Windows key combinations were passed through to the RDP session and interperted correctly.
Howver, on my Mac Book Pro, I cannot trigger any of my custom Windows key shortcuts. What is weird, is that all of the built in Windows key shortcuts still work. For example. [win]+[e] opens Windows Explorer, and [win]+[d] still minimzes all windows to show the desktop. Also, pressing the Windows button by itself bring up the start menu, as normal. But none of the user assigned key combinations involving the Windows key work is any application (I've tried three apps). Custom key bindings involving the ctrl, alt, and shift keys work as expected.
Config
I'm running:
Mac Book Pro 2017
MacOS Mojave 10.14
Microsoft Remote Desktop Version 10.1
I have the "Use Mac shortcuts for cut, copy, and paste" option unchcked from within Remote Desktop Client preferences.
Based on a different question and answer, it looks like there are some configuration files in Applications --> Microsoft Remote Desktop --> Package Contents --> Contents --> Resources --> Keyboard. However, I'm not sure what I would add to map [Win]+[something].
Check this repo
Probably you can adjust this configuration file for your goals
today after i got an update of avast i could not launch any android emulator anymore (Bluestacks 3 and NOX). When i try to launch an emulator after like 80-90% of the engine loading of the emulator nothing happens then i get a messagge of the emulator that the engine could not launche and it gives me 2 options (restart engine or restart computer) both will get my sistem to crash and i get a blue screen with errorcode 0x00000667 (not sure if i miss a 0). I already tried to disable the antivirus and to retry but got the same problem, i reinstall the android emulator but got the same result. And worst of my problems are that my computer didn't had the file protection active to restore to an prewvie point, so im stuck now and i prefer not to reset my whole computer. Any suggestion what could i do? im really in trouble here and i hope this is the right place to ask for my problem.
Turning off hyper-v in your pc will fix the problem. Run the CMD in administrative mode and run this command bcdedit /set hypervisorlaunchtype off.
Solve this
1 - Enable virtualization (from bios/UEFI setting)
2 - Disable hyper-v and restart (Credit to Sadhurshan)
bcdedit /set hypervisorlaunchtype off
3 - Install intel haxm
https://software.intel.com/en-us/articles/intel-hardware-accelerated-execution-manager-intel-haxm
Run the CMD in administrative mode and run this command bcdedit /set hypervisorlaunchtype off.
I had the same problem.
Run the CMD in administrative mode and run command
bcdedit /set hypervisorlaunchtype off.
But just this step didn't work.
As a second step, I checked whether Intel X86 Emulator Accelerator (HAXM installer) is installed on the SDK Manager > SDK Tools. I saw the "update available" and updated it.
Problem is solved.
I was having the same exact issue. Did all the normal troubleshooting (restarts/re-installs etc). So I hit up google and found your post and made the connection that I recall updating Avast a few days ago as well. Did a search for "avast bluestacks" and found the post # this URL. I followed its easy steps and so far bluestacks is back up and running normal for me again.

disable hyper-v and restart then open nox try again in windows 10 disable
Press Windows key.
Type "Turn Windows features on or off"
Deselect checkbox next to Hyper-V.
Select OK.
Select Restart now.
Never expected that this would work, but it worked for my good old fasion i7-2600k which does not support VT but has Hardware acceleration.
Make sure Hyper-V is disabled in Windows Features
Uninstall NoxPlayer (probably similar to Bluestacks)
Disable Hardware Acceleration in your BIOS
Install NoxPlayer, do a first run with an emulator.
Restart and enable Hardware Acceleration in your BIOS again to improve performance.

The problem can easily be solve by using following steps:
Turn off battery saver mode if it ON.
Close the bluestack application.
Open task manager or Press Ctrl+shift+Esc and end all Background process with bluestack.
(The 3-4 process are
Bluestack 4
Bluestack Agent
Bluestack Android host
Bluestack Server Interface
).
Close all applications.
Restart the bluestack application.
I also faced the same issue on my new spec: R5 5600X on MSI B550M.
This is how i solved it:
Uninstall windows updates: Didn't Work.
Enable SVM(Must be enabled anyway): Didn't Work.
Refresh Windows(Download from Cloud): Worked :)
I'm doing some driver development on my Windows machine and I've been wondering why pressing the PrtSc (print screen) button to take a screen capture seems to hang my machine. There are some forums that suggest this happens when the DEBUG boot option is set in Windows and that this is a panic/bug-check in the Windows kernel.
Is this a Windows bug? Or is this actually useful in some way, like in Linux where PrtSc/SysRq is actually a kernel interrupt key?
UPDATE #1: I'm using Windows 7 x64 Professional Build 7601.
https://msdn.microsoft.com/en-us/library/windows/hardware/ff541727(v=vs.85).aspx
You can disable the SYSRQ key by editing the registry. In the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\i8042prt\Parameters registry key, create a value named BreakOnSysRq and set it equal to DWORD 0x0. Then, restart the computer. After you have restarted the computer, you can press the SYSRQ key on the target computer's keyboard and it will not break into the kernel debugger.
Obviously, you're likely using a usb keyboard, so make sure to add the BreakOnSysRq = 0 value data pair to kbdhid\Parameters (and for good measure hidusb and kbdclass, not i8042prt. This will prevent the PrntScr key from being interpreted as SysRq.
I'm using Chrome Remote Desktop on a Windows Desktop to access an Apple iMac. I cannot figure out how to invoke the Apple Command key function from my Windows keyboard. I would think that the Windows key would work but it doesn't. Is there a way to map the Windows key to the Apple Command key? I really want to be able to invoke copy and paste from the keyboard, which are Command-C and Command-V on the iMac, so I'm stuck because I don't have a "Command" key.
My solution to this problem is to leverage the handy "Configure Key Mapping" command provided by the latest version of Chrome Remote Desktop (v. 77.0 at the time of writing). The option is available in the sidebar as shown below.
Clicking the link opens the "Configure Key Mapping" dialog, from which you can create your own mapping. An important thing to note is that the keycodes supported by Chrome Remote Desktop are not the usual "ASCII" codes to which every developer is used to (I did this error myself the first time); rather, the codes should be taken from the "UI Events KeyboardEvent code Values" W3C standard. If you go through the standard you'll find the useful "List of code values for functional keys in the Alphanumeric section" table, which I also replicate below.
Concretely, let's say you want to map your local (Windows) Ctrl key to the remote (Mac) Cmd key. From the table above we see that the code for the (left) Ctrl key is "ControlLeft", while the code for the Cmd key is "MetaLeft", so from the "Configure Key Mappings" dialog:
click "New Mapping"
enter "ControlLeft" in the "from" field
enter "MetaLeft" in the "to" field
if needed, click [New Mapping] to enter more key mappings
the configuration should now look like in the image below. Click [Done] to close the dialog window.
At this point you should be able to use Ctrl-C, Ctrl-V etc. on your local PC to trigger the corresponding Cmd-C, Cmd-V etc. commands in the remote Mac. The solution works quite well for me and it resolves a perennial problem of how to use the Cmd button while on a Windows PC without having to rely on external apps or plugins.
I'm on a Windows 10 machine remoting into an El Capitan Mac (yes, it's an old OS, but it's a 2009 model that can't be upgraded any higher). If the other solutions don't work for you (they didn't for me), you can try adding Mac keyboard shortcuts in Keyboard settings. I use this mac as a home server and only use it via Chrome Remote Desktop, so I am not worried about messing up keyboard shortcuts when using the computer's keyboard directly.
Go to Settings > Keyboard > Shortcuts > App Shortcuts and add new shortcut mappings for Copy and Paste to the Ctrl key.
On Windows 10
Alt + Window + C
Alt + Window + V
On an Acer C7, the right control key maps to command. In fact, the Search key maps to command too, which is far more helpful, but available on fewer keyboards.
Well, it seems I can use the Windows Key to send the CMD Key straight away to the Mac machine. I have tried:
Windows + C: copy
Windows + V: paste
Windows + X: Cut
Windows + W: close window
Windows + Q: close application
All work nice!
However you can't use this:
Windows + Tab: switch between applications,
it is already used by Windows for the same function.
But you can still use "holding the mouse middle wheel and moving the mouse up" to see all open applications. It is a little bit painful, but does most jobs.
If things don't work - try map MetaRight to ControlLeft
I have windows keyboard connected to a mapbook. I had to swap the modifier keys: Command <-> Control.
The problem was that when connecting with the Chrome Remote Desktop to a Linux machine, the remapping MetaLeft to ControlLeft did not work. Turned out it's because the macbook remapped the left key to the MetaRight what whatever reason.
I have confirmed, using chrome remote desktop, that search+another_key does the same as CMD+another_key while remote-connected to my mac-book pro over home WiFi. I also noted that if I want to enter two search+another_key presses sequentially, I must release and repress the search key after each instance
You can map keybindings, just not that im on a mac remoting to a windows PC (with a windows keyboard) and I noticed that MetaRight is the windows key (as oppose to Meta left).
If you want to use e.g. WIN-key + C to represent Cmd + C on mac, other than "Configure key mappings" (WIN-key seems mean Cmd on mac by default?), you need to go to full-screen checkbox by the right-side's blue-sliding bar (F11 doesn't work for me).
Only in that full-screen mode, WIN-key + something is not occupied by the Windows OS.
Go Full-Screen first
In order to use all shortcut keys, you need to go full screen from the Windows PC that is accessing the Mac. This option can be found in the side menu on the right.
Then use the ⊞ Win key for all the ⌘ Cmd key shortcut keys on Mac
