How to cause a BSOD on Windows XP and newer versions?

Is there a way to programmatically cause a BSOD on Windows XP and newer versions? How?

BTW just to clarify, this is not for malicious purposes. The client requested to be able to shut down/reboot a terminal on their LAN this way. When I asked why, they said because it's faster than a normal reboot... :)

(I'm curious which part of "programmatically" do those people not understand who migrated this to Super User. Duh.)

Answer

The keyboard driver(s) can be told to cause a BSOD:

HKLM\SYSTEM\CurrentControlSet\Services\kbdhid\Parameters

or (for older PS/2 keyboards)

HKLM\SYSTEM\CurrentControlSet\Services\i8042prt\Parameters

And there set a REG_DWORD named CrashOnCtrlScroll to 1.

After the next reboot you can force the blue screen by Ctrl+ScrollLk+ScrollLk. The bug check code will in this case be 0xE2 (MANUALLY_INITIATED_CRASH).

If you really want a programmatic method, you need to find a hole in some driver on that machine or write and install a simplistic driver that calls either KeBugCheck or KeBugCheckEx.

Have fun ;)

Side-note: it can be very useful to deliberately cause a crash like this for driver writers or even when dealing with malware. If you configured your system to create a full memory dump, you will then have an image of the running system which can be further analyzed. Consider cases like a deadlock where a debugger does not necessarily help in all cases.

Use Google instead of Bing with Windows 10 search

I want to use Google Chrome and Google search instead of Bing when I search in Windows 10. Google Chrome is launched when I click on web, but it's Bing search. (My default search engine on Google and Edge is http://www.google.com ) I haven't found how to configure that. Someone can help me ? Answer There is no way to change the default in Cortana itself but you can redirect it in Chrome. You said that it opens the results in the Chrome browser but it used Bing search right? There's a Chrome extension now that will redirect Bing to Google, DuckDuckGo, or Yahoo , whichever you prefer. More information on that in the second link.

linux - Using an index to make grep faster?

I find myself grepping the same codebase over and over. While it works great, each command takes about 10 seconds, so I am thinking about ways to make it faster. So can grep use some sort of index? I understand an index probably won't help for complicated regexps, but I use mostly very simple patters. Does an indexer exist for this case? EDIT: I know about ctags and the like, but I would like to do full-text search. Answer what about cscope , does this match your shoes? Allows searching code for: all references to a symbol global definitions functions called by a function functions calling a function text string regular expression pattern a file files including a file

How do I transmit a single hexadecimal value serial data in PuTTY using an Alt code?

I am trying to sent a specific hexadecimal value across a serial COM port using PuTTY. Specifically, I want to send the hex codes 9C, B6, FC, and 8B. I have looked up the Alt codes for these and they are 156, 182, 252, and 139 respectively. However, whenever I input the Alt codes, a preceding hex value of C2 is sent before 9C, B6, and 8B so the values that are sent are C2 9C, C2 B6, and C2 8B. The value for FC is changed to C3 FC. Why are these values being placed before the hex value and why is FC being changed altogether? To me, it seems like there is a problem internally converting the Alt code to hex. Is there a way to directly input hex values without using Alt codes in PuTTY? Answer What you're seeing is just ordinary text character set conversion. As far as PuTTY is concerned, you are typing (and reading) text , not raw binary data, therefore it has to convert the text to bytes in whatever configured character set before sending it over the wire. In other words, when y...

linux - CentOs 7.1 - Install Tomcat 8

I am using this tutorial as a setup reference to getting a Tomcat 8 running on CentOs 7.1 , but after typing: [root@localhost tomcat]# sudo systemctl start tomcat I get the error: Job for tomcat.service failed.
