Every once in a while, people discover the MenuShowDelay registry value that controls how long Windows waits before a submenu pops open, and writes it up like buried treasure. I’ve seen the headlines promising an instant desktop, comparisons to Windows XP’s responsiveness, and the claims of a night-and-day difference. So I tried it myself on my MSI Cyborg 15, starting conservatively and working my way down to zero. Here’s what actually happened.

A 30-year-old setting still buried in the registry

MenuShowDelay is a registry entry at HKEY_CURRENT_USERControl PanelDesktop, and it’s been there since Windows 95, back when the registry itself was still new. It sets the pause in milliseconds for cascading submenus to appear when you hover over a menu item that has one. Microsoft built in the delay decades ago so that a sweeping mouse movement wouldn’t accidentally pop open menus you didn’t mean to open. The default is set to 400ms, which works out to about half a second of artificial hesitation.

To find it yourself, hit WIn + R, type regedit, then navigate to HKEY_CURRENT_USERControl PanelDesktop. MenuShowDelay shows up there as a string value, already set to 400. Double-click it, change the number, then sign out and back in (a restart works, too) for it to actually take effect.

The tweak itself really mostly manages the older Win32 menu system still running under Windows 11’s surface. That means it affects File Explorer’s right-click context menu, the New and Send To submenus, Control Panel dialogs, and the file type picker in Save dialogs. The modern Start menu is built on WinUI/XAML and ignores MenuShowDelay entirely, so don’t expect that to speed up.

I tested three values, and the results were underwhelming

Starting conservatively at 50ms

I started by changing the delay to 50ms, a value a few other write-ups say is the sweet spot. I restarted my computer, signed back in, then went looking for the dramatic difference everyone says is there. I didn’t find it. Right-clicking files, opening Send To, working through Control Panel menus: it all felt basically the same as the default.

So I went even lower. At 0ms, the delay is apparently removed entirely, and this is whereI could finally tell that something had changed, mostly in nested submenus like NEw and Send To. It’s still not the amazingly noticeable jump that some writers promise, but more of a small, easy-to-miss improvement that matters most in the menus I tend to open on a daily basis. Shaving 400ms off each menu interaction seems silly if it’s just one time, but after a while, that adds up.

I still don’t run into the accidental menu popping problem some writers warn about at 0ms, though that might be more about how I use a mouse than anything else. I also tried 20ms as a middle ground between the two, but mostly to rule out the possibility that 50ms just wasn’t enough. It was still not super noticeable.

Why your mileage will vary more than the headlines suggest

It’s about architecture, not magic

Windows 11 is a hybrid of old Win32 menu code and newer WinUI surfaces, and MenuShowDelay only controls the former. On a modern CPU with a fast SSD, the Win32 menu system was likely never an actual bottleneck. 400ms is only perceptible when you’re looking for lag, not when you’re using Windows 11 normally. That’s probably why my results came in as marginal, rather than instant. I suppose if something else is lagging on my machine, this could help it feel a bit snappier, but for now, I don’t see the point.

There’s also a psychological advantage, in that an older laptop is already going to feel pretty slow; getting rid of lag in the menus will help everything seem a little faster in relation to that. Plus, if your context menus are cluttered with shell extensions from apps like cloud storage or antivirus apps, the genuinely slow loading won’t feel like a fix, since 400ms won’t even register. On a clean, fast machine like mine, the baseline is closer to instant already, which leaves less room for a registry tweak to dramatically improve on it.

Still, if you’re looking for every possible trick to make your desktop feel faster, MenuShowDelay is a pretty quick fix to enable. It’s also fully reversible if you feel like it. Just don’t expect it to transform your PC on its own. For a bigger jump in perceived speed, try disabling background services you don’t actually need or working through a broader list of registry tweaks will likely move the needle more than this one value alone.

Where this leaves the registry tweak

MenuShowDelay is a real, three-decade-old setting that actually controls submenu timing, and dropping it to 0ms did shave a tiny bit of hesitation off the menus I open frequently. What it isn’t is the super exciting instant fix that keeps getting written up that way. If your PC already feels pretty responsive, this is just a minor polish to that. I’ll keep mine at 0 since there’s no real downside, but the revelation I hoped for never appeared.
