Windows Server 2019 ISO: Official Download from the Evaluation Center

The Windows Server 2019 ISO is free to download from the Microsoft Evaluation Center, the only official public source. Register, pick the 64-bit ISO and your language. Done. It installs a 180-day evaluation. Later, a retail or volume key turns that install into a licensed server.

1. Open the Windows Server 2019 page on the Microsoft Evaluation Center.
2. Choose ISO, the 64-bit edition.
3. Register and pick a language.
4. Save the ISO. Use it for a USB stick, a DVD or a virtual machine.
5. Activate over the internet within 10 days of installing.

Where to download the Windows Server 2019 ISO

One place. The Windows Server 2019 page on the Microsoft Evaluation Center. That’s Microsoft’s own download for anyone without a volume licensing account, and it costs nothing.

Three choices sit on that page:

• ISO, 64-bit. The one most people want, for bare metal or any hypervisor.
• VHD, 64-bit. A ready disk for Hyper-V, English only.
• Windows Server on Azure. A cloud trial, no download at all.

Companies with a volume licensing agreement get their keys through the Microsoft 365 admin center instead. Same product, different door. Everyone else uses the Evaluation Center.

Step by step on the Evaluation Center

A couple of minutes before the download starts:

1. Open the Windows Server 2019 page. Pick ISO.
2. Register. The page asks for it before the download.
3. Choose the language.
4. Click the 64-bit edition link. The browser saves the ISO.

Languages for the ISO:

• English, United States. Also the VHD language.
• Chinese, Simplified.
• French and German.
• Italian and Spanish.
• Japanese and Russian.

Need another language? Language packs go on after setup. We’d download the English ISO if nobody on the team minds, since every format exists in English.

What’s inside the ISO: editions and install options

One image, several choices. Setup shows a list, and you pick before the disk is touched:

Pick carefully. Since Windows Server 2016 a Desktop Experience evaluation can’t become a Core retail version. A Standard Core evaluation converts only to Datacenter Core. Wrong choice? Then we’d plan for a fresh install.

Standard or Datacenter? Mostly a question of virtual machines and storage features. Our Windows Server editions guide lays out the differences. Not sure 2019 is even the right release? Our comparison of the last three Server releases helps.

180 days, 10 days to activate: the evaluation rules

Two numbers to remember. The evaluation runs for 180 days. And it has to activate over the internet in the first 10 days, or it starts shutting itself down. So we’d connect the server to the internet on day one, even in a lab.

Not sure what’s installed? Either of these, from an elevated prompt:

DISM /online /Get-CurrentEdition
slmgr.vbs /dlv

Eval in the edition name? EVAL in the slmgr output? Then you’re on the trial. The desktop also shows the days left, bottom right, until Windows is activated. Our slmgr commands list explains the rest of that output.

Minimum hardware requirements

Modest numbers. Microsoft’s minimums for 2019:

A catch for virtual machines. Setup fails on a VM with only 512 MB of RAM. Give it 800 MB or more during install, then lower it if you like.

From the Windows Server 2019 ISO to a USB stick or a VM

Virtual machine first, since it’s the easy one. Hyper-V, VMware and the rest all take the ISO directly as a virtual DVD. Attach it, boot, install.

Physical server? Then a USB stick of 8 GB or more. On a Windows PC, double-click the ISO to mount it. Copy the files to a FAT32 stick. One snag: FAT32 can’t hold a file over 4 GB. Is install.wim bigger? Then we’d split it into .swm pieces, which Windows Setup reads from the sources folder. Microsoft’s split command:

Dism /Split-Image /ImageFile:C:\sources\install.wim /SWMFile:E:\sources\install.swm /FileSize:3800

More detail on the stick itself? Our guide to creating a bootable USB drive uses the same ideas. The setup screens after boot match our Windows Server 2022 install walkthrough almost one to one. Forgot how to mount an image? Our guide to mounting an ISO covers it.

Convert the evaluation to a full license

No reinstall needed. Microsoft documents an in-place conversion with DISM. Elevated prompt, three steps.

See which editions this install can become:

DISM /online /Get-TargetEditions

Then set the edition with your key. ServerStandard and ServerDatacenter are the usual names:

DISM /online /Set-Edition:ServerStandard /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX /AcceptEula

Restart when asked. A few rules from Microsoft’s conversion page:

• Standard Evaluation can become Standard or Datacenter.
• Datacenter Evaluation can only become Datacenter.
• A domain controller can’t be converted. Promote a second, licensed server, move the roles, then demote the evaluation one.
• Target not listed by Get-TargetEditions? A fresh install of that edition is the only way.

Microsoft’s edition conversion guide has the full table. The same flow on the next release is in our page on converting Server 2022 evaluation to Standard, and the commands are identical.

KMS client keys: they install an edition, not a license

Microsoft publishes generic KMS client keys for volume licensing setups. They install an edition. They don’t activate it on their own. Activation only happens against a KMS host on your network, which companies run with their own host key.

No KMS host? Then these keys leave the server unactivated. Our Windows Server KMS keys page lists every release, and how KMS activation works explains the host side.

Sites offering a full Windows Server 2019 ISO download

Plenty of them. Direct links, so-called full versions, Google Groups posts with mirrors. We’d skip all of them.

The evaluation ISO already is the full product. The same bits accept a retail key, so there’s nothing to gain from a stranger’s upload and a lot to lose. A server holds passwords, domain data and backups. Nobody can say what a reworked image carries.

Already running 2019 and need to start it in Safe Mode? See booting Windows Server 2019 in Safe Mode. Ready to license the trial? Our Windows Server 2019 Standard key comes with a direct Microsoft download link and is delivered instantly by email.
