More and more people now run both Claude tools on the same Windows machine: Claude Desktop for chat, research and everyday work, and Claude Code in the terminal for building software. On paper they complement each other perfectly. In practice, running them side by side creates a quiet mess - because both default to a single shared configuration tied to your one Windows user account.
This article explains where the friction comes from, and how to run Desktop and Code together with each context fully isolated: separate logins, separate MCP servers, separate settings.
Claude Desktop and Claude Code are separate programs with separate config files - but by default they both live under your single Windows profile. That leads to three recurring problems:
None of this is a bug. It's just what happens when a single-user desktop app meets a multi-context workflow. The fix is to give each context its own isolated home.
Claude Desktop Manager creates named profiles - Work, Client A, Personal, a coding sandbox - and launches Claude Desktop with a dedicated --user-data-dir for each one. Everything that profile touches lives in its own folder: its login session, its window position, its settings. You can have several of them open at the same time, each signed into a different Anthropic account, with zero cross-contamination.
What that gives you day to day:
Isolation, not duplication. Each profile is a separate data folder, not a second copy of Claude. You still install Claude Desktop once - Claude Desktop Manager just decides which isolated context it opens into.
A common layout that works well:
From any profile you can open its terminal and run Claude Code against exactly that isolated configuration. When a project ends, you delete the profile and everything that belonged to it goes with it - no leftover credentials, no stray MCP entries in a global file.
If you also juggle several Anthropic accounts, the companion piece to this is running multiple Claude Desktop accounts at the same time, and if you want each project to carry its own tools, see giving each Claude profile its own MCP servers.
Yes. They are separate programs and can run simultaneously. The friction is configuration: both read from shared Windows locations, so accounts, settings and MCP servers bleed together. Claude Desktop Manager gives each profile its own isolated data folder so Desktop and Code stay cleanly separated per context.
They are distinct tools with distinct config files, but by default both live under your single Windows user profile. That means one set of credentials and, in practice, one working context. Claude Desktop Manager isolates each profile's data directory so you can keep a separate login, MCP set and settings per project.
Create one profile per context in Claude Desktop Manager - Work, Client A, Personal. Each profile launches Claude Desktop with an isolated data folder and can open a terminal with the profile's own Claude Code config. No logging out, no mixed history.
No. Claude Desktop Manager is an independent third-party tool. It is not made by, affiliated with, or endorsed by Anthropic.
Claude Desktop Manager is free to download. Standard ($10, one-time purchase) unlocks 2 simultaneous instances with no time limit. Pro ($30, one-time) removes all limits and adds QuickPrompt and QuickAsk.
