    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. 😒

    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.

      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?

    • @QuickenFixen
      @QuickenFixen 3 года назад +33

      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.

      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.)

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.
