Two people, one PC, both needing to work at the same time — and no budget for a server this month. These are the workable, honest options, including what each one cannot do, so you can pick with your eyes open.
Most 'we need two sessions' problems are really 'we need two people productive' problems, and sessions are only one way to solve those. This page lines up the legal, no-patch options for a two-person collision on one PC, from free habits you can start today to the purchase that usually wins on price.
At a glance: only the last two rows give two people genuinely independent, simultaneous desktops.
The zero-cost option is better than most offices realise once it is organised. Give each person their own user account. Whoever is at the PC works locally; the other connects by Remote Desktop when the machine is free and reconnects to their own session, apps exactly as left. Because reconnecting to your own session does not disturb your own work, a simple rota — mornings for billing, afternoons for reports, or whatever fits — carries many two-person offices surprisingly far.
Its limit is obvious and honest: it is a queue, not a second desktop. If both people truly need the machine in the same hour every day, read on.
A large share of 'second user' requests are really help requests: 'show me how you did that entry', 'fix this error on my screen'. For those, Windows already ships the answer — Quick Assist (and its older sibling Remote Assistance). The helper sees the same screen, can point, explain, and with permission drive the mouse and keyboard.
What it cannot do is give the helper a private desktop of their own. Both people are looking at — and sharing — one session. The companion page on assistance versus full sessions draws this line in detail.
A virtual machine is a second, complete Windows running in a window (or full screen) on the same hardware — one person works on the host, the other inside the VM, truly independently. Windows 10/11 Pro include Hyper-V for this.
Legal and workable, but you pay in hardware headroom what you save in licences.
Do the simple maths the patch videos skip. A refurbished office desktop costs less than most people expect, needs no special licensing beyond its own Windows, never breaks on Patch Tuesday, and gives the second person a real, independent machine — their own session, their own screen, zero collision with the first PC, which can stay the shared file and Tally host with one remote user at a time.
For exactly two people, this is very often the cheapest total answer — cheaper than the CAL stack, and incomparably cheaper than monthly wrapper firefighting once you price the downtime.
Microsoft will happily rent you the second desktop: Windows 365 and Azure Virtual Desktop provide per-user cloud PCs for a monthly fee, reachable from any device. For a two-person office with good internet this works and is fully licensed by construction.
The honest caveats: the fee never stops, the experience lives and dies with your internet connection, and your shared local data (that Tally folder) still sits in the office — plan how the cloud desktop reaches it, usually through cloud storage or a VPN, not by magic.
Watch the video to see the single-PC multi-user problem in action, then match it against the options compared here.
▶️ Watch Full VideoNot with standard Windows — extra screens and keyboards still belong to the one interactive session. Third-party multi-seat products exist, but on client Windows they run into the same one-session licence limit this series describes.
The VM needs its own Windows licence. The licence that came with the PC covers the installation running directly on that hardware, not an additional copy running inside it.
Separate user accounts with a simple time rota, plus Quick Assist whenever the real need is help rather than a second desktop. Both are built into Windows and need nothing installed.
