    No Windows will refuse todo particular file systems resizes to NTFS partition while the file system is on-line.

    4) you must learn partition tables and how to work with them
    5) you must learn to identify partitions
    Not a single point that true. There are graphical interfaces like gparted you can use.

    7) you must not make mistakes (you can easily kill all your data by using fdisk/gdisk/gparted/etc.).
    This applies to using Windows disk manager have you not read the Microsoft Administrators guide.

    Stop moving the goalposts. There is no shell needed, contrary to your claims. Creating a USB flash drive with Linux on it is trivial and there are also GUI tools which will perform that for you.

    Um, you may want to re-read the part in bold again. My arguments are based on what Microsoft says and what independent journalists have discovered after using Windows key checker tools on test purchases of Windows keys. Your arguments are based on TFYA.

    No, you get 3(?) activations in that timeframe. However, if you attempt to re-install one of these keys a few months later, activation could fail.

    Microsoft themselves warn about this.

    Beware of Product Keys Sold Separately
    With the exception of Product Key Cards (PKC’s) distributed with COA’s, Microsoft does not distribute products keys as standalone products. If you see a listing on an auction site, online classified ad, or other online page advertising product keys for sale, it’s a good indication that the keys are likely stolen or counterfeit. If you were to purchase and use a stolen or counterfeit product key to activate Windows installed on your PC, the key may not work for activation, may already be in use on another PC, or it might be blocked from use later by Microsoft when the key is reported stolen.

    Their German website is even more explicit:

    Einzelne Product Keys für OEM-Versionen von Windows 10 können ebenfalls problematisch sein. Wenn z.B. ein solcher Product Key noch nicht zur Aktivierung verwendet wurde, also scheinbar „neu“ ist, dann kann es sich um einen Product Key handeln, der bei einem OEM-Partner entwendet wurde, was in der Vergangenheit leider vorgekommen ist.

    They will perfectly fine activate the Windows 10 ISO image that you can download directly from Microsoft.

    Now on to your egregiously false statement. No, you cannot resize mounted ext4 volumes.
    I said enlarge, and ext4 does support online enlarging. And I did this many times with gparted. And firmwares like Armbian do it all the time.

    For the reading-challenged, I said:

    gparted (and parted from commandline) and KDE partition manager can online resize, as long as the filesystem does support the feature.

    ext4 and xfs do support online enlarge for sure, btrfs supports everything, you can move it and resize it online.


    this is an example of doing this with a commandline tool, but gparted can also do the same (as it's just a frontend for the same tool)
    https://www.systutorials.com/5621/ex...-lvm-in-linux/

    Extend the ext4 file system
    The resize2fs (manual) can resize an ext4 file system on-line to use all available disk capacity. We can resize the /home mounted by:

    resize2fs /dev/vg/lv_home

    It will prints output like follows if it executes successfully
    resize2fs 1.42.9 (4-Feb-2014) Filesystem at /dev/vg/lv_home is mounted on /home; on-line resizing required
    old_desc_blocks = 18, new_desc_blocks = 77
    The filesystem on /dev/vg/lv_home is now 319283200 blocks long.


    You can use df -hT to check the file system’s available capacity and start to saving more files under /home now.

    OEM Windows 10 license costs measly $100
    Pfft, you're the usual fucking loser. Buy illegal OEM licenses from ebay sellers at 5$ a pop, they are available since Windows 7 was a thing. They send you the license key within hours in an email. No issues, and even if they decided to block it, it's 5$, so who cares.

    which people even in the third world countries are able to afford.
    Yes, 100$ is very affordable in third world countries, can confirm (hint: it's bullshit).

    Don't bother replying to me - I don't see your messages anyway. Now on to your egregiously false statement. No, you cannot resize mounted ext4 volumes. In Linux, on a normally booted/running system, you cannot unmount root fs (technically you can but it's near impossible for 99% of people out there). Nice try but try harder.

    Speaking of Windows. OEM Windows 10 license costs measly $100 which people even in the third world countries are able to afford. But you can install Linux and have sex with it as long as you don't value your time.

    I was hit by this a couple days ago. Sucked, but I had most things backed up and could restore the rest. This is the first time I had any issues with bcache, after using it for what has to be over five years now.

    For those wondering if birdie is posting bullshit as usual:

    OEM licenses are linked to the motherboard's unique ID code, you can't take the same license key and input it to activate a new motherboard as the ID won't match anymore.

    Most modern OEM licenses from Windows 8 onwards are not even on a sticker anymore and are phisically written in the board firmware's SLIC tables. Extracting them from a dead system would require specialized hardware.

    99.9999% of sellers, especially on Ebay are selling MSDN keys (they activate retail Windows and don't expire) or some other type of volume license bought by a large institution. This is of course illegal.

    Also, sale of ANY OEM license regardless of its source is ILLEGAL. They are licenses to be sold to system integrators and OEMs, not end users.

    The fact that MS isn't revoking the licenses does not mean they are legal. You can install Windows 10 without any fucking license at all and it will still work perfectly fine with only minor issues.

    this is bcache, the cache filesystem bcachefs is based on.

Again, this is absolutely simple in Windows and doesn't require you to have anything or deeply understand anything.

    That may be because you are generally not well informed about Linux, Windows, or computers at all.

    It does happen in practice that Microsoft no longer accepts such keys for activation after a while.

    The fact is Linux' I/O and file system are superior to Windows. Not only throughput, but latency. Windows crawls when there's I/O activity. On Linux it's also sometimes noticeable, but it's a different thing. Birdie is example of exstinc species of astroturfers.
