Microsoft Will Preload Windows 11 File Explorer to Hide the Impacts of Bad Performance.
tomrod•15m ago
Windows 11 is so bad. It's worse than Vista. Microsoft took everything decent about Windows after the Windows 8 debacle and decided if it works it needs to break.

It's unfortunate. Microsoft had the talent to have premier products but is stuck in second or third on everything.

Appropriate, if funny: https://ritholtz.com/wp-content/uploads/2013/07/2011.06.27_o...

Every other windows version is terrible. Therefore, I bet windows 12 will be pretty decent, as far as windows goes.

It’s like they say, only alternating versions of Windows are actually worth using.

It’s almost like they follow a software version of Intel’s old tick-tock pattern. A version that’s super experimental, but unstable and flaky (95, Me, Vista, 8, 11) and a version that irons out the wrinkles and pared down some of the worst parts to make a solid OS (98, 2000/Xp, 7, 10).

Didn't all Windows from 95 onwards preload explorer?
SkyArrow•11m ago
Yep, explorer.exe has always started up in the background. Pure speculation here, but this change likely involves preloading the UI surfaces and supporting bits such as disk free space, network share status, thumbnails etc.

First this is a very editorialized title, the original is:

"Announcing Windows 11 Insider Preview Build 26220.7271 (Dev & Beta Channels)"

Secondly, they're preloading the executable resident in memory to accelerate click to open, similar to what Chrome Browser does on Windows (and websites when browsing)

I don't perceive this as "fixing bad performance, given explorer has never been slow to open for me, but rather further optimizing the experience.

Wait a minute, they’re preloading “explorer.exe” ???

Performance wasn’t an issue 20 years ago. Now it is ???

That takes effort!

The File Explorer in Windows has so much tech debt behind it.

It's quite obvious to see which parts are still Win32 and which are XAML. The two different context menus are a well-known example, but one that really annoys me is the Home view vs. the This PC view.

If you make Explorer open with the This PC view by default, you get a blinding flash of white every time you create a new tab in dark mode. That doesn't happen with the Home view which has been updated to XAML.

It's one of the many things you experience day to day that really makes me disappointed in the level of quality in modern Windows.

IIRC they started preloading Office application recently as well.

They have done that for at least ten years, I believe, with "Click to Run".

Surprised it’s not branded something like copilot 365 files (formerly explorer)
