What Windows Software Should You Check Before Migrating to Linux?

The safest Linux migration starts with an inventory, not a list of alternative apps.

Before removing Windows, identify the software you actually depend on and classify each item by how it would work after the move.

Build the list from real use

Do not rely only on the installed-programs screen.

Include:

• desktop applications;
• browser-based services;
• Office macros and add-ins;
• PDF/signature tools;
• VPN software;
• printer/scanner utilities;
• password managers;
• accounting software;
• creative tools;
• game launchers;
• device-management software;
• industry-specific applications.

The program that blocks a migration is often the one used once a month but absolutely required.

Classify each dependency

For each item, put it into one of these buckets:

1. Official native Linux support
2. Official browser-based workflow
3. Acceptable native Linux alternative
4. Compatibility-layer experiment
5. Virtual machine or remote Windows access
6. Windows still required

That classification keeps "it might run" separate from "the vendor actually supports this."

Browser-based does not mean feature-identical

Microsoft 365 for the web can provide browser versions of Word, Excel, PowerPoint and OneNote.

Outlook on the web currently works in Firefox and Chrome on Linux, but Microsoft notes that some features may be unavailable.

That means a browser path can be viable without being identical to the Windows desktop application.

Test the actual documents, meetings, shared calendars, macros and add-ins that matter to you.

Some products are strong Linux candidates

Google Chrome has official Linux builds.

Slack currently supports a Linux desktop app on supported Ubuntu LTS and RHEL releases.

QuickBooks Online currently supports use in a Linux browser, while Intuit says its QuickBooks Online Advanced desktop app does not.

Those differences are exactly why product name alone is not enough.

Some desktop software remains a blocker

Adobe's current Creative Cloud desktop system requirements list Windows and macOS, not Linux.

That does not mean every Adobe-related workflow is impossible on Linux, but it does mean you should not describe Creative Cloud desktop as officially supported there.

If a workflow depends on Photoshop, Premiere Pro, Acrobat plugins or another Windows/macOS-only desktop product, treat that as a real migration dependency.

Check files, not just applications

A replacement application is only useful if it handles your real data.

Test representative examples:

• large spreadsheets;
• tracked-change documents;
• presentations;
• PDFs;
• proprietary project files;
• templates;
• macro-enabled documents;
• shared-drive files.

File-format support can be more important than whether a replacement program exists.

Check hardware-dependent software separately

Some applications exist only to operate hardware.

Examples include:

• printer/scanner utilities;
• label printers;
• audio interfaces;
• firmware tools;
• security keys;
• specialty USB devices.

A successful software audit must include those dependencies too.

One Windows dependency can change the plan

If one critical application remains Windows-only, you do not automatically have to abandon Linux.

Possible outcomes include:

• keep one Windows workstation;
• dual boot;
• use remote Windows access;
• keep Linux for users who do not need the application;
• postpone migration.

The goal is not to force every program onto Linux. The goal is to know what will break before the Windows installation disappears.
