dump - Externally enable minidump creation in Windows


I'm still in the process of fixing this problem, and user Moab suggested analyzing the dump file created during the BSOD.
I can boot into Hiren's BootCD PE, hoping I would be able to find dump files in C:\Windows\Minidump, but there is not a single file to be found. Makes sense: I remember turning the feature off.


However, is there a way to enable the creation of (mini) dump files in a Windows 10 installation using a boot disk such as Hiren's?



Answer



You can set Windows to produce mini-dump by setting


[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CrashControl]
“CrashDumpEnabled”=dword:00000003

You could set it to 7 rather than 3 to get an Automatic dump. See this MS documentation.


Depending on the dump file you want to produce you'll also need to make sure that the pagefile exists and is big enough. From a boot disk you could set this key


[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management]
"PagingFiles"="C:\pagefile.sys 400 400"

The 400 are 400MB minimum and maximum - to set to automatic you would set the value to "C:\pagefile.sys 0 0" - This is taken from this TechNet PowerShell script.


You can do this certainly do this from a boot disk by updating the host registry. There is an external Tenforums.com tutorial on editing offline registries if you don't know how to do this. There is also a specific tutorial for using Hirens here


None of this however is going to give you a dump for a previous event though. If the dumps you want don't exist then they don't exist. Changing rules about producing them in future will only make them appear next time not retrospectively.


In that case while you could make these changes from a boot disk you could equally well make them from the failing system itself. Set the page file size to automatic, set the system to produce dumps and try to recreate the error.

keyboard - Is there any utility/method to change Windows key bindings to type rare chars to currently empty bindings?

I'm currently typing this post with my windows XP machine and (Spanish) keyboard, and I'd like to add some extra symbols to my text. I could open the "char map" windows utility, look for the desired symbols, and paste them. But I'd like something quickier. For example, when I'm using my OSX Mac at work, I can easily add a ©, ™, ® or similar symbols, just pressing some weird ALT-GR + G / H / J, key combinations. In my (Spanish) keyboard mapping, these combinations are empty, as they don't produce any char at all, which, on the other hand, is perfectly normal and desirable. So, I thought: Why couldn't I add some extra key mappings on top of my currently empty ALT-GR + G/J/H Keys in my Spanish keyboard, and thus, being able to quickly type these special symbols? So that's my question: Is there any utility/method to achieve that effect under windows? (My version is XP). I've even googled this for some time but no luck. I've been a long term Hot...

virtualization - How to select paravirtualization interface in VirtualBox?

Given a windows 8 host system (Intel Core i5) and a Linux Fedora host, I would like to determine the optimal setting for the paravirtual interface. Options are none Default Legacy minimal Hyper-V KVM This page suggest the selection is only based on the guest system: The biggest change in VirtualBox 5.0 is the introduction of paravirtualization support, bringing higher performance and time-keeping accuracy to supported guest operating systems (Hyper-V on Windows and KVM on Linux). Is that correct? Answer The VirtualBox Manual , in the section titled Paravirtualization providers explains very clearly when each should be used (emphasis added): Minimal: Announces the presence of a virtualized environment. Additionally, reports the TSC and APIC frequency to the guest operating system. This provider is mandatory for running any Mac OS X guests. KVM: Presents a Linux KVM hypervisor interface which is recognized by Linux kernels starting with version 2.6.25. VirtualBox's implementati...
