Kliknite vezu  Uključivanje ili isključivanje značajki sustava Windows na^{(Turn Windows features on or off)} lijevoj ploči prozora Programi^(Programs) i značajke^(Features) .

Pronađite  Microsoft Defender Application Guard  s popisa na zaslonu značajki sustava Windows^{(Windows Features)} i označite potvrdni okvir pored ove opcije kako biste ga omogućili. Pritisnite tipku  OK  .

Nakon što omogućite Microsoft Defender Application Guard , morat ćete ponovno pokrenuti svoj stroj. Da biste onemogućili Microsoft Defender Application Guard , jednostavno poništite opciju na zaslonu Značajke sustava Windows^{(Windows Features)} i ponovno pokrenite računalo.

2] Omogućite^(Enable) ili onemogućite Application Guard za Office pomoću PowerShell -a^(PowerShell)

Također možete omogućiti Microsoft Defender Application Guard za Office pomoću PowerShell -a . Da biste otvorili PowerShell kao administrator, desnom tipkom miša kliknite gumb Start i odaberite  Windows PowerShell (Administrator)^{(Windows PowerShell (Admin))} .

Kopirajte i zalijepite sljedeću naredbu u prozor PowerShell kako biste omogućili Windows Defender Application Guard i pritisnite tipku ENTER :

Da biste onemogućili Application Guard za Office , unesite sljedeću naredbu:

Disable-WindowsOptionalFeature -online -FeatureName Windows-Defender-ApplicationGuard

3] Uključite ^(Turn)Microsoft Defender Application Guard u grupnoj politici Managed Mode

Dvije gore navedene opcije su načini za omogućavanje ili onemogućavanje Application Guard za Office . Nakon dovršetka bilo koje od dvije gornje metode, sada morate uključiti značajku u grupnoj politici Managed Mode .

Da biste to učinili, idite na  Computer Configuration > Administrative Templates > Windows Components > Microsoft Defender Application Guard .

Ovdje promijenite vrijednost pod  Opcije^(Options) u  2  ili  3 . Kliknite na  gumb OK za spremanje postavki i zatvaranje prozora. Nakon ovoga ponovno pokrenite računalo.

4] Još jednom provjerite^{(Double-check)} je li Application Guard za Office omogućen i radi li

Nakon što omogućite Microsoft Defender Application Guard za Office , nećete dobiti potvrdu da radi. Možda biste željeli potvrditi da ste ga omogućili i da radi ispravno.

Prije nego nastavite još jednom provjeriti jeste li omogućili Application Guard za Office , otvorite aplikaciju Microsoft Office ( Word , PowerPoint , Excel itd.) na računalu koje ima implementirana pravila i provjerite imate li aktiviranu kopiju Microsofta Ured^{(Microsoft Office)} . Ako nije aktiviran, morate ga aktivirati da biste koristili Application Guard za Office .

Da biste provjerili je li Application Guard omogućen i radi li, preuzmite dokument ili privitak e-pošte s interneta tako da bude klasificiran kao nepouzdani^(untrusted) . Zatim ga otvorite u odgovarajućoj Office aplikaciji.

Kada prvi put koristite aplikaciju Office za otvaranje nepouzdanog dokumenta, možda ćete primijetiti da se početni zaslon prikazuje dulje vrijeme. Ovo kašnjenje je zato što aktivira Application Guard za Office i otvara datoteku. Međutim, to se događa samo prvi put. Ostala otvaranja bit će brža.

Ako je Microsoft Defender Application Guard omogućen, vidjet ćete naznaku toga na uvodnom zaslonu. Na primjer, Microsoft Word će reći,

To keep you safe, we’re opening this document in Application Guard…

Kada se datoteka konačno otvori, još jedan pokazatelj aktivnog Application Guard za Office je da ćete na vrpci vidjeti oblačić koji kaže:

File opened in Application Guard.

This file is from an untrusted soure. To keep you safe, we’ve opened it in a protected mode.

Također, primijetit ćete crni štit na ikoni Microsoftove^(Microsoft) aplikacije na programskoj traci. Ovo je još jedan pokazatelj da je Application Guard omogućen i da radi.

Nadam se da ovo pomaže.

3. Turn on Microsoft Defender Application Guard in Managed Mode group policy.
4. Double-check if Application Guard for Office is enabled and working.

The first two solutions are alternative ways to enable or disable the Application Guard for Office. The third part should be done after following one of the solutions. And finally, you’ll see how to confirm that the Application Guard for Office is enabled and working.

After enabling Microsoft Defender Application Guard, you’ll need to restart your machine. To disable Microsoft Defender Application Guard, simply uncheck the option on the Windows Features screen and restart your computer.

2] Enable or disable Application Guard for Office using PowerShell

You can also enable Microsoft Defender Application Guard for Office using PowerShell. To open PowerShell as an administrator, right-click on the Start button and select Windows PowerShell (Admin).

Enable-WindowsOptionalFeature -online -FeatureName Windows-Defender-ApplicationGuard

On running the above command, you’d have enabled Application Guard for Office. Restart your computer following this to finish the process.

To disable Application Guard for Office, enter the following command:

3] Turn on Microsoft Defender Application Guard in Managed Mode group policy

The two options above are ways to enable or disable the Application Guard for Office. After completing any of the two above methods, you now have to turn on the feature in the Managed Mode group policy.

To do this, go to Computer Configuration > Administrative Templates > Windows Components > Microsoft Defender Application Guard.

Here, change the value under Options to 2 or 3. Click on the OK button to save your settings and close the window. Restart your computer after this.

4] Double-check if Application Guard for Office is enabled and working

After enabling Microsoft Defender Application Guard for Office, you get no confirmation that it’s working. You may want to confirm that you’ve enabled it and it’s working correctly.

Before you go ahead to double-check that you’ve enabled Application Guard for Office, open a Microsoft Office app (Word, PowerPoint, Excel, etc.) on a computer that has policies deployed and ensure that you have an activated copy of Microsoft Office. If it’s not activated, you must activate it to use Application Guard for Office.

To check that Application Guard is enabled and working, download a document or email attachment off the internet so that it’s classed an untrusted. Next, open it in the corresponding Office application.

The first time you use the Office application to open an untrusted document, you might notice that the splash screen shows for a longer time. This delay is because it’s activating Application Guard for Office and opening the file. However, it happens only the first time. Other opens will be quicker.

If Microsoft Defender Application Guard is enabled, you’ll see an indication of that in the splash screen. For example, Microsoft Word will say,

To keep you safe, we’re opening this document in Application Guard…

When the file finally opens, another indicator of an active Application Guard for Office is that you’ll see a callout in the ribbon that says,

File opened in Application Guard.

This file is from an untrusted soure. To keep you safe, we’ve opened it in a protected mode.

Also, you’ll notice a black shield on the Microsoft application’s icon in the taskbar. This is another indicator that Application Guard is enabled and working.

Hope this helps.
