Windows Subsystem for Linux (WSL)

Comparing WSL 1 and WSL 2

https://learn.microsoft.com/en-us/windows/wsl/compare-versions

WSL 1 (released 2016-08) neobsahuje ziaden kod z Linux kernel a funguje na principe prekladu systemovych volani Linux na Windows. Nepouziva ziadnu emulaciu ani virtualizaciu, takze je mozny priamy pristup k hostovskemu (NTFS) suborovemu systemu (pomocou VolFs a DrvFs).
Linux distribution in directory C:\Users\<user>\AppData\Local\wsl\<distribution unique uuid>\rootfs\ (location by default).

WSL 2 (released 2019-05) nahradzuje WSL 1 preklad systemovych volani virtualizaciou plnohodnotneho Linux kernelu pouzitim Hyper-V VM technologie. WSL 2 pouziva virtualny disk (ext4 formatted filesystem). Windows pristupuje k suborom Linux ako klient, ktory komunikuje prostrednictvom 9p protokolu so serverom, ktory je spusteny vo vnutri WSL 2. See also [1], [2] and [3].
Linux distribution in virtual disc file C:\Users\<user>\AppData\Local\wsl\<distribution unique uuid>\ext4.vhdx (location by default).

D:\            9p    282G  102G  181G  37% /mnt/d

Rozdielny pristup k suborom OS file systems:

Vyhoda WSL 2 je v podstatnom zrychleni (cca 5x — 20x) prace so subormi v ramci Linux file systems (WSL ⇄ WSL, WSL 2 better, WSL 1 worse).
Slaba stranka WSL 2 je pomalsia praca so subormi napriec roznymi OS file systems (WSL ⇄ Windows, WSL 2 worse, WSL 1 better).

Linux GUI apps are only supported with WSL 2 and will not work with a Linux distribution configured for WSL 1.
Vseobecna sa odporuca pouzivat WSL 2 a dalej budeme pod WSL rozumiet WSL 2.

Install WSL

PS D:\> wsl --help
PS D:\> wsl --list
Windows Subsystem for Linux has no installed distributions.
You can resolve this by installing a distribution with the instructions below:

Use 'wsl.exe --list --online' to list available distributions
and 'wsl.exe --install <Distro>' to install.
PS D:\> wsl --list --online   # https://github.com/microsoft/WSL/blob/master/distributions/DistributionInfo.json

NOTE

wsl --install <Distro> = stiahnutie <Distro> + interny import + prvotne nastavenie (Out-of-Box Experience, OOBE)
wsl --import <Distro> = manualny import (rozbalenie <Distro> rootfs a nic viac)

See also how install, import and build custom distribution.

Install Fedora

Fedora distribuuje znacne mnozstvo roznych obrazov (images), ktorych pocet sa casom meni. Vyznat sa v tom je znacne komplikovane, ale hlavne, co plati dnes uz neplati zajtra. V principe pre WSL sa moze pouzit rootfs z lubovolneho obrazu. Zjavne vsak pouzitie rootfs z napr. Fedora Workstation nie je prilis vhodne, kedze obsahuje mnozstvo nepotrebnych balikov, o.i. grub, kernel, drivers/firmware, xorg/wayland a pod. Naopak je vhodny nejaky minimalisticky obraz. Fedora (od verzie 42, released 2025-04) zacala vytvarat novy image priamo pre WSL.

Fedora WSL image vychadza z Fedora Container (Docker, Podman) image, ktoreho rootfs obsahuje len tie najzakladnejsie baliky programov + pridava wsl-setup (OOBE).

PS D:\> wsl --install FedoraLinux-43   # DistributionInfo.json
PS D:\> wsl --install FedoraLinux-43 --name Fedora43 --location C:\Linux\Fedora43
PS D:\> wsl --install --name Fedora43 --location C:\Linux\Fedora43 --from-file Fedora-WSL-Base-43-1.6.x86_64.wsl

NOTE *.wsl is renamed *.tar or *.tar.gz/xz

# recommended: download nightly stable image of Fedora-WSL-Base from koji or to same from kojipkgs
PS D:\> wsl --install --name Fedora --location C:\Linux\Fedora --from-file Fedora-WSL-Base-43-20251115.0.x86_64.wsl

NOTE Pre DNF 5 (od Fedora 41) funguje upgrade pre WSL rovnako ako napr. pre bezny Workstation upgrade
[WSL2-Fedora ~]# sudo dnf system-upgrade download --releasever=43
[WSL2-Fedora ~]# sudo dnf5 offline reboot
PS D:\> wsl --shutdown   # reboot

# Fedora WSL specific packages
$ sudo dnf install glibc-all-langpacks xdg-user-dirs xdg-utils emacs-pgtk

Microsoft licencia

OEM (Original Equipment Manufacturer) licencia vacsinou nadobudnuta s kupou noveho pocitaca, hardveru a pod. Priviazana ku konkretnemu hardveru (pozor EU legislativa, moznost prenosu). Najvacsia vyhoda je cena. Aktivacia je vacsinou automaticka cez internet pripadne telefonicky.

FPP (Full Packaged Product), Retail (maloobchodna) klasicka licencia zakupeneho produktu v obchode, ci uz krabicova verzia (DVD) alebo elektronicka (download from store). Plne prenosna a casovo neobmedzena. Aktivacia podobne ako pri OEM licencii, online cez internet alebo offline telefonicky.

Volume license (VL) pre vacsie mnozstvo pocitacov v organizaciach, podnikova sfera (enterprise). Multilicencie ponukaju vacsiu flexibilitu, rychlejsiu implementaciu a samozrejme vyhodnejsiu cenu. Pre male mnozstvo licencii je mozna aj online manualna aktivacia. Pre hromadnu aktivaciu existuju v podstate dve moznosti:

MAK (Multiple Activation Key), kde kazdy MAK kluc obsahuje konkretny pocet licencii. Administrator firemnej siete pomocou nastroja VAMT (Volume Activation Management Tool) moze preverovat pocet aktivnych, dostupnych licencii. Aktivacia je casovo neobmedzena.
KMS (Key Management Services) v ramci firemnej siete musi byt nakonfigurovany server a Software Licensing Service s KMS klucom. Aktivacia prebieha pripojenim na firemny KMS server. Takato aktivacia je casovo obmedzena (180 dni), potom potrebna opatovna aktivacia pripojenim na KMS server.

OEM a Retail licencie su urcene pre beznych uzivatelov, Volume licencie su vhodnejsie pre podniky a vacsie organizacie.

Právna poznámka: Ďalší predaj softvérových licencií (vrátane OEM) je v rámci Európskej únie úplne legálny. "Tvorca počítačových programov nemôže brániť ďalšiemu predaju použitých licencií a hoci teda licenčná zmluva zakazuje ďalší prevod, majiteľ práva nemôže brániť ďalšiemu predaju tejto rozmnoženiny", píše sa v rozsudku Súdneho dvora EÚ v prípade Case C-128/11 UsedSoft GmbH/Oracle International Corp.

Windows 7

Чем отличаются Retail и OEM дистрибутивы?
Единственным отличием имиджей является содержимое конфигурационного файла выпуска ei.cfg, никаких других отличий нет. Совпадают даже размеры дистрибутивов. Файл настройки выпуска (ei.cfg) определяет устанавливаемый выпуск или же канал (Channel) распространения Windows и лицензию, используемую во время установки. Удаление файла настройки выпуска (ei.cfg) разблокирует выбор редакций систем Windows 7, а именно станет возможным самостоятельно выбрать какую именно редакцию системы Windows 7 устанавливать: Windows 7 Starter, Home Basic, Home Premium, Professional или же Windows 7 Ultimate.

Все (crack) ОЕМ-активаторы работают по одному принципу. Они ставят эмулятор SLIC в загрузочную область жесткого диска (MBR область). Но методы установки у всех разные. ULoader я советую именно потому, что там большой выбор SLICs (хотя большинство НОВЫХ активатов имеют такие функции), его не валит проверка на подлинность и он умеет себя полностью удалять.

Разрядность х86/х64 и язык не влияют на ключ.

На MSDN раздаются Retail образы (кроме корпоративной (VL) и редакции Starter (она ОЕМ)).

Windows

With Volume Licensing (VL) for products you must use Volume Activation (VA). To activate these products with VA, you can use either a Multiple Activation Key (MAK) or Key Management Service (KMS).

How to get Volume Licensing Keys: Look up the product for which you need a key. Information on how to get your key will be displayed. Not all Volume Licensing products require a key. Volume license (VL) products using Volume Activation (VA) are pre-installed with a Key Management Service (KMS).

How do I get my key? (Office): Keys can be obtained from VLSC or by calling the Activation Call Center. The KMS key will enable you to activate all Office 2016 client products (Office Professional Plus, Visio, and Project). There are MAK keys for suites and standalones. Visio and Project are not part of any suites, so they have separate MAK keys. The only time you will need MAK standalone keys is when you are deploying standalone products.

How do I get my key? (Windows): Keys can be obtained from VLSC or by calling the Activation Call Center. The KMS and MAK keys are assigned; they will enable you to activate both Windows 10 Professional and Windows 10 Enterprise.

At the command prompt, type: slmgr.vbs -dli and hit Enter. A dialog will appear listing the full name of the edition. Another interesting thing this dialog displays is the channel the operating system is from, whether is OEM, Retail, Volume License Client.

MeGUI

Windows 7 x64 + AviSynth64 sice funguje, ale nie je mozne (zatial) prehravat *.avs subory v MPC-HC, preto (zatial) len 32-bit verziu MeGUI (ten vsak aj tak pouziva 64bit wrapper na x264 !)
AviSynth je 32-bit preto potrebny aj ffdshow 32-bit a nakoniec aj mpc-hc 32-bit, okrem ineho aj SubtitleWorkshop tak isto len 32-bit => all complet only 32-bit
pre dir C:\Program Files (x86)\MeGUI pre istotu radsej ihned nastavit Security userovi Users (mucha-PC\Users) ako Full Control
minimalne potrebne baliky, ktore je potrebne stiahnut pred instalaciou priamo z internetu: megui.org/auto alebo mirror megui.xvidvideo.ru/auto

Notes

UAC uplne vypnut. Pozor ak znova zapnem UAC tak niektore config files sa citaju z ineho miesta, napr. subor s konfiguraciou Button Bar v TC, settings pre MediaInfo, ...
avisynth.dll klasicka 32-bit kniznica sa nachadza v C:\Windows\SysWOW64. V dir C:\Windows\System32 je len asi "kvazi symbolicka linka", ktoru mozno zobrazit napr. pomocou Total Commander. Ak prezeram subory cez Windows Explorer, tak ten tuto kniznicu v dir C:\Windows\System32 ani len nezobrazi.
Pridat cestu C:\Program Files (x86)\MeGUI\tools\eac3to do systemovej premennej PATH
Media Player Classic - Home Cinema uz dalej defaultne nepodporuje Store settings to .ini file (asi problemy s UAC), vsetky nastavenia sa zapisuju priamo do registrov
- Options -> Player -> Formats pridam napr. k Video File (avi) okrem koncovky .avi aj koncovku .avs ⇒ Video File (avi avs), nezabudnut potom na Association (from gray icon to black)
- zmena ikonky .avs z MPC-HC ikonky na AviSynth ikonku, ale nadalej subory .avs budu asociovane (budu sa otvarat) s MPC-HC

hladam Progid: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.avs\UserChoice ⇒ Progid = mplayerc64.avs

menim ikonku: HKEY_CLASSES_ROOT\mplayerc64.avs\DefaultIcon ⇒ (Default) = C:\Windows\SysWOW64\avisynth.dll

ak neexistuje key DefaultIcon tak ho vytvorim (prava myska na mplayerc64.avs, New -> Key)
