Dynamic selection lets gohide pick windows automatically by their title or window class, instead of ticking each app by hand. It's built for programs that spawn windows on the fly — File Explorer (a separate window per folder), a web browser, an image viewer that opens a window per image, anything that pops fresh windows while you work. Define a rule once and every matching window — now and in the future — is hidden the instant it appears.

Dynamic selection is a Pro feature.

How matching works

A rule matches windows in one of two ways:

• Title contains — any window whose title contains your text (case-insensitive). Browser windows carry the browser name in their title bar, so Edge or Chrome hides every window of that browser; Down would catch a File Explorer window showing your Downloads folder. Don't include quotation marks.
• Window class (exact) — any window whose class name equals one you list (case-insensitive). Use this to catch all of one app even when its titles differ — e.g. CabinetWClass for File Explorer, or Chrome_WidgetWin_1 for Chrome / Edge.

To match several things at once, separate them with a semicolon (;):

Edge;ACDSee;Photoshop
CabinetWClass;Chrome_WidgetWin_1

Create a rule

1. Open Settings → Dynamic selection.
2. Click Add title rule or Add class rule.
3. Enter your patterns (semicolon-separated). The Test button shows how many open windows match right now — handy for checking a pattern isn't too broad.
4. Optionally choose what happens while hidden — keep running, suspend the process, or mute it — and whether to hide the tray icon too. Assign a hotkey if you want to toggle the rule from anywhere.
5. Save. The rule appears in the list with a Hide / Show toggle.

Hiding and showing

Press Hide on a rule (or its hotkey) to arm it. gohide hides every window that matches right now, and a live monitor keeps watching: any new window that matches — a browser pop-up, a freshly opened document — is hidden the moment it appears.

Press Show on that rule to release it: its windows come back and gohide stops auto-hiding them.

A rule that is hiding takes priority over everything else. While a dynamic rule is armed, its windows stay hidden even if you press Show all or the panic-restore hotkey. Only turning that specific rule off reveals them. This is deliberate — it lets you keep a class of windows permanently out of sight while still using show-all for everything else.

Auto-hide a startup program after every reboot (Pro)

A signature use of gohide Pro: some program launches itself at every Windows logon — a chat client, a download manager, a game or store launcher — and you'd rather it never appear. Dynamic selection can keep it hidden automatically, with no clicks after the first setup.

In the registered (Pro) edition your rules — and whether each one is currently hiding — are saved (encrypted, bound to your license). Turn on Start at logon (Settings → General) so gohide itself returns with Windows, elevated and with no UAC prompt. Then:

1. Create a rule that matches the program (by title or class) and press Hide once.
2. After every Windows (or gohide) restart, gohide comes back, re-applies the rule, and the program is hidden the moment its window appears — you never even see it flash.

It doesn't matter whether the program starts before or after gohide: gohide hides matching windows that are already open at startup, and keeps a live monitor running for windows that appear later, so either order is covered.

Tips

• Substrings are powerful but broad — Down also matches "Download" or "Countdown". Use the Test count, or a more specific phrase, to avoid hiding more than you meant to.
• Class matching is exact, so it never over-matches the way a title substring can. Use a tool like Spy++ or rely on the Test count to find the right class name.
• gohide never matches Windows shell processes or itself, so system windows are safe.
