Firefox crashing before pressing enter is because when hovering over a URL/typing one in it auto loads it before clicking on it to make it load "faster" Source: Firefox user
3:52 This wasn't Windows trying to prevent repeated misuse, what happened was that when you saved the file, it wasn't written to the disk, it was in a disk-cache, and you crashed the system before the buffer was flushed to disk, but the MFT contains the expected size of the file, so when you open it, it just shows the correct number of bytes, but all null. This is an insidious problem that most people aren't aware can happen. I learned it the hard way one day when I had a BSOD and upon reboot, noticed that some files that had been created just before the crash were now blank. If I hadn't noticed, they would have remained blank but still set to the expected size and no indication of corruption. The reason I noticed was because the files were image files and when I rebooted, I noticed they weren't showing thumbnails. If not for that, I could have continued on, blissfully ignorant of corrupted files forever. Now, whenever Windows crashes, I boot into safe-mode to prevent files from being written to the disk, then do a search for files created or modified in the past day, and check the last few that were touched before the crash to see if they were corrupt. If you want to avoid losing data of an important file, you can get Uwe Sieber's drive-tool FFB to manually tell Windows to Flush File Buffers to ensure the file is written out to disk. It's one of the most important tools. This happens on internal drives that have their policies set to optimize speed since they're not removable; removable drives like flash-drives and memory-cards default to quick-removal and should write data directly to the drive, not to a buffer (at the expense of speed). You can usually change the policy of drives in the Device Manager. 5:44 Or you can hold down the Shift key to prevent startup items from running. Also, you put it in "shell:startup" which puts it in the current-user's auto-run. Holding Shift during boot will prevent the system from automatically logging into the user's account, so you can log into a different user and delete it from there. If you put it in "shell:common startup", then it would run on boot, so you'd have to hold Shift to prevent auto-run from running. 7:53 This is probably a race-condition, the shell is trying to run the random file before it's finished being written. Try changing the command to put the run command on the same line as the copy command with with double-ampersands (&& instead of &) to require to only run if the copy command has returned success. 8:11 It's heuristics. Defender is detecting "suspicious activity". 8:50 Yup, this problem was only on Windows 10, not older versions. I keep saying, not all updates are good, in fact, most updates just make things WORSE, not better. 😒
Reminds me of that one time I hadn't done my homework, so I opened the word fike in notepad++ and deleted parts of the header, making the file look corrupt. In the meantime I finished the assignment. Teacher never suspected a thing
I actually killed my pc lmao, don't try this. I used the link and my Windows wouldn't boot after it crashed. I didn't matter tho as I have dual-boot with Linux and made an installation usb to fix Windows, but it could be dangerous for people that don't know how to fix it themselves if it happens. Please don't send this to anyone.
I didn't meant I've created a bat or something and put it inside shell:startup. What I did was just opening it on my browser. No screen of death showed up, my computer just restarted and after selecting the Windows option in grub the computer would just get stuck, no loading icon, nothing, just a black screen with the Windows logo in the middle, I left it loading for 10 minutes and realized it could boot. After that, I turned off the computer by holding the power button and started my pc with Ubuntu. Ubuntu started without any problems in less than 30s. From there I just created the Windows installation disk/usb and booted it up. After one startup fix Windows would boot again. Pretty weird right?
@@DownloadableFox Once BSOD (not caused by this glitch, caused by malfunctioning RAM stick, even Linux threw kernel panic) screwed up my bootloader but I think this is extremely rare. I fixed it by using bcdedit but diskpart would probably do it as well. And also of course by replacing the wrong stick.
No doubt the reason the file is being replaced with zeros is that it crashed before the disk cache was flushed, so the file content hadn't actually been written to disk yet. If you create the file and then reboot normally, it should stay. That also explains why some other methods didn't have that problem, because they took longer and did more file I/O, so the cache had time to be flushed. This is also why it's important to shut down properly.
3:48 it's not really intentional - the file is blank because data doesn't get flushed to disk soon enough - the task scheduler and other things are stored in registry which is never saved when system crashes - if you've created a file and waited a moment or better - restarted the system before doing anything, it should would work as expected

Wow that’s really interesting. Is there any documentation on the thing where Windows replaces the characters with null bytes in the batch file? I’ve actually been seeing that exact thing happen on some Windows machines at my job and couldn’t figure out why an XML file had a bunch of null bytes in it instead of the data I expected.
I suppose it could be, but there’s over two dozen involved servers virtualized in a enterprise data center. The number of null bytes matches the amount of characters I would expect to be in the file and it happened right as the operating system crashed. We think it’s related to antivirus software scanning it at the time.
Using Windows 10 feels like being in a volatile and dysfunctional relationship with a crazy girlfriend. Not “let’s jump out of a plane” crazy, but “let’s eat our baby” crazy.
I suspect defender notices the self-copying file and when it tries to kill/inspect it, it runs into the path, makes a request to see what the file contains (to find out if the file is part of the malware) , and then confuses the computer into BSOD'ing
@@FlyTechVideos My guess would be either: A: it expects some commands/parameters to be executed along with the command itself B: It requires a very specific system state(pre-login,Safe mode,"configuring updates", etc.) Unlikely options: C: it's Linux software/IO references that Windows mistakes for compatible software but again, I'm just guessing, (also, I don't really use Windows anymore, because of ideas like forced updates etc.)

I’m very glad you tested on previous NT-based Windows to be thorough. I was tempted to check NT 3.51 and 4.0 but I highly suspect they’re safe from this. BTW, you might be able to prevent it from running upon startup of Windows if you hold the Shift key in some cases.
Of course older version don't have this problem, it was introduced in Windows 10. That's why updates are NOT a good thing, they usually ADD MORE bugs than they fix. 😒
@@artdeellIt’s an endless loop. People don’t update, so updates are forced. Inevitably at least one update breaks everything, and now more people don’t want to update.
dude i havent got bsods in a looong time. after watchin this video i got bsod right before i shut my computer down. damn i wasnt expecting this, so friccin scary
Microsoft fixed this bug with the new February 2021 Patch Tuesday updates. If you try to trigger this bug after installing recent updates, Windows no longer crashes to a BSOD. Instead, it will only give errors like "Element not found" but the system will continue to function normally.
@@pmcpicto I tested that in Windows 11 build 22621.2070 and it didn't crash the computer. It said "Element not found". So it is now safe to enter that command in Windows 11.
When I was in university, there was Windows 98 or 95 on computers, Norton Commander, Turbo Pascal etc. So, once I was looking onside different files and inside IO.SYS I found all those device names - CON, PRN, LPT1, COM1 etc, including CLOCK$. So I edited this file and changed "CLOCK$" to "SYSTEM". As a result, when Windows tries to boot, it just hangs before switching to graphics mode, with error message something like "Cannot find blabla.vxd". I don't remember exact text, nor name of that file, probably vmm32.vxd. You can boot to dos using F8, and use dos programs, but you cannot cd into any folder named SYSTEM.
it happened in the video (you can see it very briefly because I sped up 400% during that portion, and I also reset the machine so I don't get to the recovery page)
i got trolled by my friend he sent me that link then my laptop crashed and my monitor just starts to say no signal SO I SEE THIS IS USEFULL FOR TROLLING
8:12 Windows Defender is trying to read the code of the exe and found the file path, so when it try to open the file path to scan it ,windows just crash
This appears to have been patched as of KB4601319. Inputting this in Firefox caused my computer to freak out for a couple of seconds, but quickly stabilized back without crashing. Inputting it on the command prompt did nothing.
@Executed you can legit just flash a new windows install, or you can boot off a usb, mount the old hard drive and recover files. Or literally just remove it from startup in 15 seconds.
They should display only image-based extension, thus avoiding the problem. So, I learn that Internet open up site like files on our local drive. Why they didn't make another pathway to isolate potential treat? 6:57 HAAAA!!!! Only four error window?
With the zip file thing when it is extracted and the system restarts does it stay extracted because I really want to prank some friends but I’m worried it’ll do permanent damage. So is it a one time bsod or every time the file location is then opened
Each time bsod happens, a system process such as updates could be interrupted causing OS or files to be corrupted (similar to unplugging computer without shutting down) so I recommend you don’t do it.
@@melom578 You can use bluescreen simulator and u can exit it on F7 it s prank i tried it on my laptop multipie times and i could exit normally without any problems
Something interesting happens when doing this in VBox with EFI enabled: I have a windows 10 host, testing this bug with a Windows 10 VM running off Vbox EFI (experimental I think). The path crashed the VM as expected. Then the machine rebooted... And a few seconds later my *HOST* BSODed from a VirtualBox driver exception... DRIVER_IRQL_NOT_LESS_OR_EQUAL....
in like late 90s AOL they let you play sounds in the chat if you typed in a short command and the filename and if you tried playing con/con it would bsod anyone who hadn't disabled their sound
I'm on my phone so I can't check but can webpages redirect in any way to a local resource? I'm pretty sure the open() function won't work but what about editing the url directly?
i tried anything i could think of (window.location.href, window.location.replace, window.open etc) and every time i got the error. i even tried generating an a-element into the dom and setting the url to the bad path, but still got stopped by the local-protection. the protection really applies to everything.
I would be interested in a video that explores the consequences of changing the function to not require parameters, if that isn't how windows dealt with it.
You can't jeally just "make" a function not require parameters. You can try to catch the exception, but that also would literally just get rid of this one BSOD and nothing else
Hey Fly, I'm really curious about the crash that keep on occurring on loop which was not intended to when defender detected a threat or so.... Did you find the reason ?
When Defender finds the threat, it tries to access the directory the threat is detected from, since the directory is the crash dir, it will crash the system, my theory anyway.
bugs and exploits like that can hide in any os, be it linux, windows, android, ios... let's not forget that systems like the ps3 get exploited just by visiting a site on the internet. and yeah, maybe windows has a higher chance of something like kernelconnect to happen, but don't pretend like you are 100% safe when it comes to things like that
@@chrisakaschulbus4903 yeah exactly. People who constantly go on saying "omg Linux is the best! It's impossible to get a virus and never has any vulnerabilities!" just give us (Linux users) a bad image, it's blatant ignorance to claim ANY system can't be infected in any way or exploited

@team lolpippiou there are hdmi capture boxes as well, for recording console gameplay
Duh

I had a BSOD yesterday, just let it restart. It doesn't harm anything for me.
I experienced a bsod on my windows 10 laptop on the first day of arrival, i was actually crying for hours and luckily i somehow fixed it
Me: *gets a 1000$ PC*
My cousin: "I'm gonna ruin my cousin's whole career
This is harmless
@Executed you can legit just flash a new windows install, or you can boot off a usb, mount the old hard drive and recover files.
Or literally just remove it from startup in 15 seconds.
@Executed I tried it. It only BSODs and cleanly reboots.
EDIT: Tried it again, the issue is fixed, no more BSOD
how would it ruin someones career?
@@natew4724 what? what files would need to be recovered? its a bluescreen..

This _does_ work in a local HTML file for me. I tested it in Brave Browser, which is a Chromium spinoff. It was reproducible as an img src.
eyy i use brave too
I don't get how Brave is 6x faster than Edge, Chrome, Firefox and Opera
@@zank8470 maybe cutting out the time spend loading code that tracks you. 6x is still a lot though...
@@lucrativelepton for me, brave is slower than edge and chrome is slower than edge
I just typed this on my laptop and it showed me a BSOD... i dunno what i was expecting
They should display only image-based extension, thus avoiding the problem.
So, I learn that Internet open up site like files on our local drive. Why they didn't make another pathway to isolate potential treat?
6:57 HAAAA!!!! Only four error window?
With the zip file thing when it is extracted and the system restarts does it stay extracted because I really want to prank some friends but I’m worried it’ll do permanent damage. So is it a one time bsod or every time the file location is then opened
it gets deleted, but i really wouldn't count on that
Each time bsod happens, a system process such as updates could be interrupted causing OS or files to be corrupted (similar to unplugging computer without shutting down) so I recommend you don’t do it.
@@nopparuj ah thanks!
Windows doesn't seem to detect it if you place the file on the desktop twice
@@melom578 You can use bluescreen simulator and u can exit it on F7 it s prank
i tried it on my laptop multipie times
and i could exit normally without any problems

Something interesting happens when doing this in VBox with EFI enabled:
I have a windows 10 host, testing this bug with a Windows 10 VM running off Vbox EFI (experimental I think).
The path crashed the VM as expected. Then the machine rebooted...
And a few seconds later my *HOST* BSODed from a VirtualBox driver exception... DRIVER_IRQL_NOT_LESS_OR_EQUAL....
0_0
Virtualbox bad
@@AhnafAbdullah you didn't try VirtualBox for yourself, did you?
in like late 90s AOL they let you play sounds in the chat if you typed in a short command and the filename and if you tried playing con/con it would bsod anyone who hadn't disabled their sound
if you go on a virtual machine thats on windows 95 or 98 or 2000 or ME, type in the run command "con/con/con" that will bluescreen the virtual machine
Me: Go to my School and set Chrome startup page to the command...
That’s so smart lmao
Don't forget to push it to GP.
I'm on my phone so I can't check but can webpages redirect in any way to a local resource? I'm pretty sure the open() function won't work but what about editing the url directly?
i tried anything i could think of (window.location.href, window.location.replace, window.open etc) and every time i got the error. i even tried generating an a-element into the dom and setting the url to the bad path, but still got stopped by the local-protection. the protection really applies to everything.
@@FlyTechVideos Yeah I tried too, well better for security I guess
@@FlyTechVideos Maybe a gigabyte of RAM would do the trick?
i just crashed my friend's computer using an html file with a link to that path

Problem: Opening this path causes a BLUESCREEN
Solution: Don't open that path.
Maybe I'm doing something wrong or this bug was fixed
So I never need to taskkill /im svchost.exe /f
@User Opening the directory doesn't need admin, but taskkill requires admin for that
0:24 its working!
I would be interested in a video that explores the consequences of changing the function to not require parameters, if that isn't how windows dealt with it.
You can't jeally just "make" a function not require parameters. You can try to catch the exception, but that also would literally just get rid of this one BSOD and nothing else
guys, stupid question here, if i try to do this will my pc be harmed in any way?
It didn't harm mine, so I think you're good
Opening this Path causes a Blue Death Screen
So this Path can cause Windows 10 to crash.
1:34 wallpaper link pls
Hey Fly, I'm really curious about the crash that keep on occurring on loop which was not intended to when defender detected a threat or so.... Did you find the reason ?
When Defender finds the threat, it tries to access the directory the threat is detected from, since the directory is the crash dir, it will crash the system, my theory anyway.
Its not working on windows 10 1511
Maybe it was fixed
For anyone wondering: yes it is patched since like over half a year ago.
Hope i'll find another bug like that.
Good Job, Windows 8.1, You Somehow Evaded The Crash.

Geee. Thanks
i tried this...
and my windows 95 won't boot up again
WHAT IT INFINITE CRASHES 95 WHAT
I remember back in the 90s people were spamming that path as a disguised URL and crashing people. It was it's own "Rick roll" type of prank

bugs and exploits like that can hide in any os, be it linux, windows, android, ios... let's not forget that systems like the ps3 get exploited just by visiting a site on the internet.
and yeah, maybe windows has a higher chance of something like kernelconnect to happen, but don't pretend like you are 100% safe when it comes to things like that
Yea before linux users get too proud they should remember the shellshock vulnerability a few years ago ;)
it can, and does happen to anyone :)
@@chrisakaschulbus4903 yeah exactly. People who constantly go on saying "omg Linux is the best! It's impossible to get a virus and never has any vulnerabilities!" just give us (Linux users) a bad image, it's blatant ignorance to claim ANY system can't be infected in any way or exploited
A great way to get myself in trouble lol
1:10 “What Failed”

5:36 What do you mean leave you alone??
Basically, enter this path and condrv.sys breaks the system with an access violation.
If we were still in school, I’d do this to the school pc and not do work
It will still restart and work.

you could do that thing where it loops whenever you boot it up lol
