Programeri, administratori sustava i napredni korisnici možda će u nekom trenutku morati raditi s varijablama okruženja. Neki će možda htjeti izbrisati varijablu okruženja; drugi će htjeti promijeniti njegovu vrijednost i tako dalje. Ovaj vodič dijeli kako urediti ili izbrisati varijable okruženja, kao i kako poništiti varijable okruženja u sustavu Windows:

Otvorite prozor Varijable okruženja^{(Environment Variables)}

Da biste izvršili mnoge izmjene prikazane u ovom članku, najprije morate otvoriti prozor Varijable okruženja . ^{(Environment Variables)}Ovaj vodič objašnjava kako to učiniti i pokazuje vam osnove rada s varijablama okruženja: Što su varijable okruženja u sustavu Windows? ^{(What are environment variables in Windows?)}.

Prozor varijable okruženja^{(Environment Variables)} u sustavu Windows 10^{(Windows 10)}

Ako želite preskočiti čitanje, jedan put koji radi isto u svim verzijama Windowsa^(Windows) je otvaranje Run window (Win + R) , naredbenog retka^{(Command Prompt)} ili PowerShell -a i izvršavanje naredbe: rundll32.exe sysdm.cpl,EditEnvironmentVariables .

Kako urediti varijablu okruženja u sustavu Windows^(Windows)

Ako želite promijeniti vrijednost postojeće varijable okoline, najprije je odaberite u prozoru Varijable okruženja^{(Environment Variables)} . Zatim kliknite ili dodirnite Uredi^(Edit) .

Kako urediti varijablu okruženja u sustavu Windows 10^{(Windows 10)}

Prikazuje vam se prozor u kojem možete urediti i naziv i vrijednost varijable. Napravite željene izmjene i pritisnite OK . Zatim još jednom pritisnite OK u prozoru Environment Variables .

Uređivanje varijable okruženja

Kako urediti varijablu okruženja iz naredbenog retka^{(Command Prompt)}

Možete stvoriti novu varijablu okruženja ili urediti vrijednost postojeće varijable okruženja (ali ne i njezin naziv) iz naredbenog retka^{(Command Prompt)} . Naredba koju morate unijeti je:

• setx varijabla_name "vrijednost"^{(setx variable_name “value”)} ako želite stvoriti varijablu korisničkog okruženja
• setx variable_name “value” /m ako ćete kreirati varijablu okruženja sustava

Na primjer, upisali smo setx TEST “C:\digitalcitizen” i kreirali korisničku varijablu pod nazivom TEST s vrijednošću C:\digitalcitizen.

Kako postaviti varijablu okruženja pomoću naredbenog retka^{(Command Prompt)}

Ako želimo promijeniti vrijednost varijable okruženja, možemo pokrenuti istu naredbu setx , ali navesti novu vrijednost za varijablu. Na primjer, izvršavanje setx TEST “C:\DC” mijenja vrijednost varijable okruženja TEST u ^(TEST)C:\DC .

Kako promijeniti vrijednost varijable okruženja u naredbenom retku^{(Command Prompt)}

To funkcionira jer naredba setx prepisuje postojeću vrijednost posljednjom koju upišete. Stoga, ako ovu naredbu upotrijebite više puta na istoj varijabli, varijabla će zadržati posljednju vrijednost koju ste upisali.

Kako dodati više vrijednosti varijabli okruženja pomoću naredbenog retka^{(Command Prompt)}

NAPOMENA:^(NOTE:) Popis svih dostupnih varijabli okruženja možete dobiti pokretanjem naredbe set u naredbenom^{(Command Prompt)} retku (ne setx i bez ikakvih parametara). Međutim, ako ste upravo stvorili ili uredili varijablu okruženja, morate zatvoriti i ponovno otvoriti naredbeni redak^{(Command Prompt)} da bi se promjene prikazale.

Kako vidjeti sve varijable okruženja u naredbenom retku^{(Command Prompt)}

Kako urediti varijablu okruženja iz PowerShell -a^(PowerShell)

Također možete stvoriti ili urediti vrijednost postojeće varijable okruženja iz PowerShell -a . PowerShell naredba za to je :

• [Environment]::SetEnvironmentVariable("variable_name","variable_value","User") ako želite stvoriti varijablu korisničkog okruženja
• [Environment]::SetEnvironmentVariable("variable_name","variable_value","Machine") ako želite stvoriti varijablu okruženja sustava

Na primjer, upisali smo [Environment]::SetEnvironmentVariable("TEST","digitalcitizen.life","User") kako bismo stvorili varijablu korisničkog okruženja pod nazivom TEST s vrijednošću digitalcitizen.life. Da bismo kasnije promijenili vrijednost varijable, možemo pokrenuti istu naredbu koristeći drugu vrijednost. Baš^(Just) kao i setx u naredbenom^{(Command Prompt)} retku , ova naredba prepisuje vrijednost navedene varijable svaki put kada je pokrenete.

Kako postaviti varijablu okruženja pomoću PowerShell -a^(PowerShell)

Ako varijabli želite dodijeliti više vrijednosti, upišite ih sve u naredbu, s točkom i zarezom između svake vrijednosti, kao što je prikazano u nastavku.

Kako dodati više vrijednosti varijabli okruženja u PowerShell -u^(PowerShell)

NAPOMENA:^(NOTE:) U PowerShellu^(PowerShell) možete dobiti popis svih varijabli okruženja pokretanjem naredbe Get-ChildItem Env:. Međutim, ako ste upravo stvorili ili uredili varijablu okruženja, morate zatvoriti i ponovno otvoriti PowerShell da bi se promjene prikazale.

Kako izbrisati vrijednost varijable okruženja u sustavu Windows^(Windows) (iz naredbenog retka^{(Command Prompt)} )

Ako želite ukloniti vrijednost varijable okruženja (a da zadržite njezin naziv), to ne možete učiniti mišem i tipkovnicom iz prozora Varijable okruženja . ^{(Environment Variables)}Ako odaberete varijablu i pritisnete Uredi^(Edit) , možete izbrisati vrijednost, ali ne možete pritisnuti OK , jer ovaj gumb postaje siv. Stoga ne možete spremiti svoje promjene.

Kako izbrisati varijablu okruženja u sustavu Windows 10^{(Windows 10)}

Međutim, možete izbrisati vrijednost varijable okruženja pomoću naredbenog retka^{(Command Prompt)} . Da biste poništili varijablu okruženja iz naredbenog retka^{(Command Prompt)} , upišite naredbu setx naziv_varijable “”^{(setx variable_name “”)} . Na primjer, upisali smo setx TEST “” i ova varijabla okruženja sada je imala praznu vrijednost.

Kako izbrisati varijablu okruženja pomoću naredbenog retka^{(Command Prompt)}

Dalje, pogledajmo kako ukloniti varijablu okruženja.

Kako izbrisati varijablu okruženja u sustavu Windows^(Windows)

Ako više ne želite koristiti određenu varijablu okoline, odaberite je u prozoru Varijable okruženja^{(Environment Variables)} . Zatim pritisnite Delete . Windows ne traži nikakvu potvrdu ove radnje. Stoga, ako ste se predomislili, morate pritisnuti Odustani^(Cancel) , kako se uklanjanje ne bi primijenilo. Ako želite da se brisanje nastavi, pritisnite OK .

Kako izbrisati varijablu okruženja u sustavu Windows 10^{(Windows 10)}

Kako izbrisati varijablu okruženja iz naredbenog retka^{(Command Prompt)}

Da biste izbrisali varijablu okruženja iz naredbenog retka^{(Command Prompt)} , upišite jednu od ove dvije naredbe, ovisno o vrsti te varijable:

• REG delete “HKCU\Environment” /F /V “variable_name” ako je varijabla korisničkog okruženja, ili
• REG delete “HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment” /F /V “variable_name” ako je varijabla okruženja sustava.

Na primjer, upisali smo REG delete “HKCU\Environment” /F /V “TEST” i naša varijabla okruženja TEST je nestala iz korisničkog profila.

Kako poništiti varijablu okruženja u sustavu Windows^(Windows) pomoću naredbenog retka^{(Command Prompt)}

Kako izbrisati varijablu okruženja iz PowerShell -a^(PowerShell)

Da biste poništili i izbrisali varijablu okruženja iz PowerShell -a, upišite naredbu:

• [Environment]::SetEnvironmentVariable("variable_name", $null ,"User") ako je varijabla korisničkog profila, ili
• [Environment]::SetEnvironmentVariable("variable_name", $null ,"Machine") ako je varijabla za cijeli sustav.

Na primjer, upisali smo [Environment]::SetEnvironmentVariable("TEST", $null ,"User") i ova varijabla okruženja je nestala iz korisničkog profila.

How to edit, clear, and delete environment variables in Windows -

Prоgrammers, system administrators, and power uѕers may need to work at somе point with environment variables. Some may want to delеte an environment variable; others will want to change its value, and ѕo on. This guide shares how to edit or delete environment νariables, as well as how to unset environment variables in Windows:

Open the Environment Variables window

To make many of the edits shown in this article, you first need to open the Environment Variables window. This guide explains how to do that and shows you the basics about working with environment variables: What are environment variables in Windows?.

The Environment Variables window in Windows 10

If you want to skip reading it, one path that works the same in all versions of Windows is to open the Run window (Win + R), Command Prompt, or PowerShell and execute the command: rundll32.exe sysdm.cpl,EditEnvironmentVariables.

How to edit an environment variable in Windows

If you want to change the value of an existing environment variable, first select it in the Environment Variables window. Then, click or tap Edit.

How to edit an environment variable in Windows 10

You are shown a window where you can edit both the name and the value of the variable. Make the modifications you desire and press OK. Then, press OK one more time in the Environment Variables window.

How to edit an environment variable from Command Prompt

You can create a new environment variable, or edit the value of an existing environment variable (but not its name) from the Command Prompt too. The command you have to enter is:

• setx variable_name “value” if you want to create a user environment variable
• setx variable_name “value” /m if you’re going to create a system environment variable

For example, we typed setx TEST “C:\digitalcitizen” and created a user variable named TEST with the value C:\digitalcitizen.

How to set an environment variable using Command Prompt

If we want to change the value of an environment variable, we can run the same setx command but specify a new value for the variable. For instance, executing setx TEST “C:\DC” changes the value of the TEST environment variable to C:\DC.

How to change the value of an environment variable in Command Prompt

That works because the setx command rewrites the existing value with the last one you type. Therefore, if you use this command multiple times on the same variable, the variable will keep the last value that you typed.

How to add multiple values to an environment variable using Command Prompt

NOTE: You can get a list of all the environment variables available by running the set command in Command Prompt (not setx, and without any parameters). However, if you just created or edited an environment variable, you must close and reopen Command Prompt for the changes to show up.

How to edit an environment variable from PowerShell

You can also create or edit the value of an existing environment variable from PowerShell. The PowerShell command for that is:

• [Environment]::SetEnvironmentVariable("variable_name","variable_value","User") if you want to create a user environment variable
• [Environment]::SetEnvironmentVariable("variable_name","variable_value","Machine") if you want to create a system environment variable

For instance, we typed [Environment]::SetEnvironmentVariable("TEST","digitalcitizen.life","User") in order to create a user environment variable called TEST with the value digitalcitizen.life. To change the value of the variable later, we can run the same command using a different value. Just like setx in Command Prompt, this command rewrites the value of the specified variable each time you run it.

How to set an environment variable with PowerShell

If you want to assign multiple values to a variable, type all of them in the command, with semicolons between each value, as illustrated below.

How to clear the value of an environment variable in Windows (from Command Prompt)

If you want to remove the value of an environment variable (while keeping its name), you cannot do that with the mouse and keyboard from the Environment Variables window. If you select a variable and press Edit, you can delete the value, but you cannot press OK, as this button gets grayed out. Therefore you cannot save your changes.

How to clear an environment variable in Windows 10

However, you can clear the value of an environment variable using Command Prompt. To unset an environment variable from Command Prompt, type the command setx variable_name “”. For example, we typed setx TEST “” and this environment variable now had an empty value.

How to clear an environment variable with Command Prompt

Next, let’s see how to remove an environment variable.

How to delete an environment variable in Windows

If you no longer want to use a particular environment variable, select it in the Environment Variables window. Then, press Delete. Windows does not ask for any confirmation of this action. Therefore, if you have changed your mind, you must press Cancel, so that the removal is not applied. If you want the deletion to go ahead, press OK.

How to delete an environment variable from Command Prompt

To delete an environment variable from Command Prompt, type one of these two commands, depending on what type that variable is:

• REG delete “HKCU\Environment” /F /V “variable_name” if it’s a user environment variable, or
• REG delete “HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment” /F /V “variable_name” if it’s a system environment variable.

For example, we typed REG delete “HKCU\Environment” /F /V “TEST” and our TEST environment variable was gone from the user’s profile.

How to delete an environment variable from PowerShell

To unset and delete an environment variable from PowerShell, type the command:

• [Environment]::SetEnvironmentVariable("variable_name", $null ,"User") if it’s a user profile variable, or
• [Environment]::SetEnvironmentVariable("variable_name", $null ,"Machine") if it’s a system-wide variable.

For example, we typed [Environment]::SetEnvironmentVariable("TEST", $null ,"User") and this environment variable was gone from the user’s profile.

That’s it!

Why did you want to learn how to edit and delete environment variables in Windows?

You now know how to do all that. But why did you want to change or edit environment variables? Was it because there were leftover variables on your system from certain apps that you no longer used? Or was it because you have a special setup, and you need to work with environment variables? Let us know in the comments section below.
