Windows 11 Notepad to support Markdown

I believe Markdown support is what led to CVE-2026-20841 earlier this month.

I was about to make a joke about how I'm surprised they haven't shoved Copilot into Notepad yet, but surprise - they have (https://support.microsoft.com/en-us/windows/enhance-your-wri...)

If notepad were to support Markdown by giving it a nice syntax highlighting and niceties like clickable links and automatic list numbering, while preserving the monospaced font, then that would be great. But with rich text formatting it has all the pitfalls of WYSIWYG editors like accidentally changing the style of something, having "formatting typos" where you tried highlighting only part of a word before making it bold, using the wrong header type, etc.

Why must they ruin notepad instead of creating a notepad++.

step 1: remove wordpad

step 2: omg there's demand for features

step 3: turn notepad, whose point was to be a dumb simple thing, into a wordpad

step 4: get a raise because you "solved" the problem

The new workflow will be "AI, I need to view this text file and add some words to it. Create an app that displays it in a scrollable window, respecting the encoding. Now move the cursor to the line below the three dashes... no, the other three dashes..."

Once upon a time, you could strip formatting from the clipboard in notepad with ^V ^A ^C, for example if you were trying to paste from edge into word. There's still a market for a non-rich text editor, without autosave, cloud, account login or AI.

Years ago replacing Notepad with an alternative was a given and everybody had their favourite. Before UTF everywhere you needed at least proper character encoding handling, other features followed.

Surprisingly, some of the projects such as AkelPad are still alive.

Win32 made things easier, as well as things like Delphi and Scintilla later.

Just checked my archives, and my own naive but functioning attempt measures whole whopping 36520 bytes, though not without the help of an executable packer, which was a fashion then.

Mostly works fine under Wine, though it is about the legal US drinking age.

They’re turning Notepad into what Wordpad was (or was supposed to be). Now everyone looking for the light weightiest *.txt editor must find a new tool...

Notepad going the way of Wordpad, EDIT.COM becoming the new Notepad.

What's next, in a few years we're rocking EDLIN when we need to operate on a text file safely?

I built a tiny Notepad clone in ~5 minutes using an LLM: open/save, plain text, no surprises.

Lately I've been doing the same for other small utilities. Roughly half the little tools I use are ones I generated and kept because they’re predictable and easy to audit.

The point isn't replacing built-ins; it's reducing dependence on shifting defaults. I want to care less about what the software/os vendor changes this time.

Markdown support isn't a bad idea, actually, as long as they don't break the most important (IMO) property of Notepad: binary WYSIWYG. I.e. if I type in some plain text and then open the file with anything else (including after moving to another machine/platform, or even viewing raw data stream in transit or on drive), I can trust to see that text, as is, and nothing else. In particular, if I restrict myself to lower 127 bytes, I expect byte-to-byte correspondence.

(Modulo CR/LF, of course.)

Why is progress always assumed to be about adding more stuff? Sometimes, taking something away would be best, but humans tend to overlook it.

Somewhere seemingly out of nowhere John Gruber got a strange sensation, like a goose walking over his grave.

So the markup dialect that's widely used but suffers from a near-total lack of viewers will now finally be rendered as intended, at least on Windows?

Markdown presents a chicken-&-egg scenario that has dragged on for decades: tons of Markdown documents, but almost nothing with which to simply view (not edit) them as intended. Mystifying.

I still say this is stupid AF, and that notepad should stay as simple as reasonable as a plain text editor and they should have resurrected "WordPad" for this purpose if they wanted it in Windows. I'm mixed on the enhancements to Paint... but this just feels a bit off.

Maybe I'd mind it less if they put the new MS Edit in Windows by default, so again, there's a minimal plain text editor in the box.

At this moment ReactOS guys should consider distributing their apps separatelly from their bundle.

On one hand, I don't feel strongly about this because I literally never use these builtin Windows tools. I can't help but think it'd just make more sense to include VSCode builtin though. It's already very good and has a nice startup time, and then you don't need to screw-up fundamental system utilities that are more break-in-case-of-emergency then something that should be feature rich.

We can just "uninstall" this notepad and it will restore old simple notepad.

Perhaps the only one pleased with this change. Another inch closer for more people to give up on this bloated O.S

For everyone that wants a simple, lightweight, alternative to notepad there's edit.exe on recent version of Windows. Assuming you don't mind TUIs.

It's like they are trying to do the opposite of the Unix philosophy. Do many things very poorly.

> We’re also adding a fill tolerance slider, giving you control over how precisely the Fill tool applies color. To get started, select the Fill tool and use the slider on the left side of the canvas to adjust the tolerance to your desired level. Experiment with different tolerance settings to achieve clean fills or creative effects.

This tool would have been so useful 25 years ago when I had to manually recolour every pixel in the contour of the cool photo I was editing for my new desktop background because the fill tool didn't recognise the background properly.

Yes. Supports .md but when you try to save back to .txt it does something to line endings that you cannot see in notepad but if you grep your .txt files from wsl like, I do all the time, you get page long strings instead of matching lines. It's weird and I haven't dug into the cause as it was easier to save as a new note but pretty sukky for an IT company to miss something like that.

Is it safe to assume LTSC versions of Windows will not have this crap shoved down their throats, as they don't get feature updates only security patches?

Markdown is a superset of HTML. Does this mean notepad is now an HTML renderer as well?

Personally I'm not happy that they are touching and revamping most basic tool of the os. A Notepad, which is a innocent little thing in itself.

Notepad should be last thing they should be fiddling with.

I am sad that we have to install 3rd parties for basics now.

This is why I uninstalled Notepad.

They are convinced it needs to be a worse vscode when all I want is something to edit plain text files.

psa: you can "uninstall" the bad sloppad and disable "App Execution Alias" for notepad.exe to get the better notepad back. just fyi

So they kill Notepad, and then turn Notepad into Wordpad? It was supposed to be like this:

- Notepad: Plain Text

- Wordpad: Rich Text

- Word: Documents

Seriously? Markdown is the preferred method for rich text these days, so why didn't they just turn WordPad into a WYSIWYG Markdown editor?

They also shove Copilot into it, but that's a whole different problem. Who is this current iteration of Notepad actually made for?

This seems to be a product management hickup. Call it either something else or add the functionality to WordPad.

When I do agentic development with Claude Code, I use notepad to read/edit the .MD files, so this will make my life a little easier.

It's becoming Word-lite, like Wordpad used to be. Paint is becoming Photoshop-lite, and now has conflicting functionality with the Photos app.

This has been supported for a while now, so I wonder why this is being treated as news. But I guess it’s news to some people, so that’s fair.

I tried to take advantage of it, but the implementation felt really clunky (formatting seemed to be via menus only), so I’ve stuck with .txt files.

Isn't Markdown how they managed to get a Severity 8.8 RCE into notepad.exe?

Honestly they lost me at tabs. I like my notepad ephemeral.

Wow, what a time to be alive in this year of 2004!

(2004 is the year Markdown was invented. Notepad got introduced in 1983 and actually predates Windows)

Just include Visual Studio Code, leave Notepad alone. Edit: On second thought, go ahead. I'm already off the OS, exactly because of things like this. The less relevant the OS becomes, the better my life will be.

> Coloring book will be available only on Copilot+ PCs. To use Coloring book, you will need to sign in with your Microsoft account.

Oh boy.

This would be a huge bonus for me if I ever had to use windows for anything.

Notepad++ already exists, is more reliable, and already has a md support plugin

recent vuln asside (big caveat ill admit) idk why you would use notepad at all when N++ exists

Oh look. Another random and unneeded feature appears in their legacy tool.

Hasn’t .md always been supported?

Is the value add for Notepad not that it is litterally the most bare bones graphical text editor available in Windows?

Microsoft has already positioned VS Code as its code editor and OneNote as its notetaking app. Why should Notepad compete with these offerings?

I don’t see why people are complaining. If you use notepad for txt files, nothing changes.

Windows 11 LTSC still has the old school notepad.exe (and calc.exe) instead of this UWP abomination. Also: https://msrc.microsoft.com/update-guide/vulnerability/CVE-20...
