It's probably very hardware dependent now, just like it was back then. My calculator opens to interactive in much less than 1 second, but I've got a 9800x3d and fast memory and nvme drive. The other guy saying his start menu takes 8 seconds to open probably has a pretty shit computer.
I definitely got the stupid hourglass in win 95 when trying to open anything, but my understanding of computers at the time was that black ones were faster than beige ones, so my computer was probably shit.
I tried to look up calculator win 95 vids on YouTube, there are a couple. One gets an hourglass - but less than a second, one is instant, one shows the calculator crashing lol.
During this I also found out that Microsoft Calculator is open source: https://github.com/microsoft/calculator

Windows UI Library
WinUI: a modern UI framework with a rich set of controls and styles to build dynamic and high-performing Windows applications.
Project mention: Microsoft is open sourcing Windows 11's UI framework | news.ycombinator.com | 2025-08-02DevExpress supported WinUI for a little while but decided to abandon support.
One of the biggest problems with WinUI compared to WPF is that DependencyProroperty is implemented as native code, so for .NET developers, there is a huge performance penalty getting or setting any property on control.

DirectXTK
The DirectX Tool Kit (aka DirectXTK) is a collection of helper classes for writing DirectX 11.x code in C++
Are there any benchmarks of Windows EH? The implementation is very different from DWARF/SJLJ EH and it would be interesting to see how they fare. I've seen some pretty exceptional claims for both sides of the argument (e.g. "[...] has no code impact for x64 native, ARM, or ARM64 platforms" [1]), but there's rarely if ever any data to back this up.
