Cheap Windows VPS under $6: licence, memory and RDP security
A Windows server for up to about $6 a month does exist, but at this price there is almost always a compromise: little memory, an old system version or a licence billed separately. Before comparing plans, it is worth understanding what the final cost is made of and from what amount of memory Windows Server works without pain at all.
The licence: who pays for it
The host rents Windows Server licences from Microsoft under its service provider programme and pays for them every month, usually based on the number of cores. That is why three models appear in the cheap segment:
- The licence is included in the plan. The price in the table is the final one. The most transparent option.
- The licence is a paid option. The plan looks cheap, and Windows is added as a separate line when ordering. Sometimes this surcharge is comparable to the price of the server itself.
- An image without a licence. The host installs the system, but activation is up to you. There is only one legal way here: buy a licence that is permitted for use at a hosting provider. Microsoft's terms generally do not allow moving an ordinary retail or OEM licence from a home computer to a rented VPS.
Separately, there is a 180-day evaluation version of Windows Server: it is legal and suitable for tests, but not for permanent work. Do not consider activators and "keys for a few dollars" at all: besides violating the licence, such programs are a common source of malicious code on a server, and the host has the right to block the machine. When comparing plans, ask straight away or look in the description whether the licence is included in the price. A general overview of versions and editions is on the Windows VPS page.
How much memory Windows Server needs
According to Microsoft's requirements, Windows Server 2019, 2022 and 2025 in Server Core mode start on 512 MB, while the desktop version needs at least 2 GB. In practice it looks like this:
- 1 GB: Server Core and a single service only, managed through PowerShell. A desktop on this amount constantly goes into the page file.
- 2 GB: the desktop and one light program: a trading terminal, a bot, a small .NET service. A browser with several tabs already eats all the headroom.
- 4 GB: comfortable work for one person with a browser and office programs. Most often this is already above this page's price limit.
On a small plan, turn off the extras: visual effects, startup programs, search indexing on the system disk. Plan for a disk of 40 GB or more for Windows: the system with updates takes 20–30 GB, and on a 30 GB disk problems with installing updates begin within six months. If several users or 1C (accounting software widespread in Russia) are planned, this budget will not do; sizing is covered in more detail on the RDP server page.
RDP security on a cheap server
A server with port 3389 open starts getting dictionary attacks within hours of being handed over. On a weak machine this is not only a risk of being hacked but also a load: thousands of login attempts noticeably take CPU and memory. What to do right after getting access:
- Set a long password and create a separate user for work, and rename or disable the built-in Administrator.
- Check that Network Level Authentication (NLA) is enabled.
- In the local security policy, set up account lockout after 5–10 failed attempts.
- In Windows Firewall, restrict the RDP rule to your own IP addresses. If your address changes, connect through a corporate VPN or a Remote Desktop Gateway.
- Check the security log once a week: event 4625 means a failed logon, and a sharp rise in them is a reason to review the settings.
- Do not postpone cumulative updates, and take a snapshot before them if the host supports snapshots.
How to choose among cheap plans
First filter out plans with less than 2 GB of memory if you need a desktop. Then compare the final price with the licence and the system version. The cheapest plans still offer Windows Server 2012 R2 and 2016: the former has not received security updates since October 2023, the latter will stop after January 2027, and keeping such a machine with RDP open is risky. Saving on the version turns into a migration a year later, so for a new server look at recent editions: Windows Server 2022 receives updates until 2031, and it is a sensible default. If you need the server for a few days, for example for a one-off job in some program, look at plans with hourly billing: many hosts bill the licence by the hour there too, but check this in the plan terms.
