Change Maximum Number of Items in Jump Lists in Windows 10  

I had to add the Reg Key and it immediately worked for me. No need to restart Explorer.exe or sign out/in.

Thanks!!!

For whatever reason, some systems require the key to be in the HKLM registry, instead (maybe in addition, I've not tried it w/o both) of the HKCU registry. So just follow all of the same steps outlined by the author, but add the JumpListItems_Maximum key to:
\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced

Again, I haven't tried it without also having this value in the same place in HKCU, so not sure if only this one matters or it requires both, but this instantly fixed it for me. No need to restart or log off or anything. Add the key with a decimal value of 25 (use whatever # you want), right click on the item in the Taskbar and it jumped form 11-12 items to 25.

My version of Windows 10 (now v 1803, Build 17134.165) has shown a maximum of 20 'Recent Files' in the Quick Access section of Explorer, ever since I started using it.

A year or so ago, I tried increasing this number, by modifying JumpListItems_Maximum (initially set at 20 as a default) as recommended by a TenForums correspondent (both HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced and HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced, even though it shouldn't have been necessary to change both, from what was said) to 30 then 60, after each of which actions the number of recent files displayed didn't change from 20.

I have just gone through this again now, for the first time with the latest release, and again there has been no change; and yes, I have rebooted. I haven't tried setting a lower limit, in case that does work, but gets stuck there.

Does anyone know of any other Windows factor - Registry key, security policy, etc - which might be constraining this? It seems that the JumpListItems_Maximum value isn't being read, or if it is, the application of its value is being denied - I have never seen any warning messages.

As another TenForums correspondent has commented, a low value for this is a pain, when it is supposed to be open, transparent, and configurable, and I consider myself lucky that it's stuck at 20, and not 11. Sounds so much like Microsoft, doesn't it?

Maybe it's as I suspect, that there is something within Windows 10 that's inhibiting or even blocking the expression of JumpListItems_Maximum, whether set in the HKEY_CURRENT_USER or HKEY_LOCAL_MACHINE branches of the Registry.

The odd thing is that changing JumpListItems_Maximum has worked for some users, but I wonder if that was in Windows 7 and 8, but not in 10. Microsoft is well known to 'deprecate' (lovely word, that) its own features, seemingly at a whim, and without telling anyone they've done so.

Equally, it seems possible (I used to do a bit of programming myself, a century or so ago) that 10 has become so complex, and so widely fiddled with, that a change in one place leads to unintended consequences in a myriad of other places. I find it hard to believe that they have complete control of how 10 behaves, in all environments.

Still, if this provokes some discussion and experimentation, perhaps we can get an answer that makes sense. I may be deluded in thinking so.

I set mine to 100 but they always seem to cap out at around 50...
and only on some applications...

Same problem here on a fresh install of Windows 10, version 1803 (17134.191). I have added the key in both HKEY_CURRENT_USER and HKEY_LOCAL_MACHINE to no avail. I rely on jumplists much more than the start menu, desktop icons, or any other way of accessing files and applications, so I hope we can figure this out soon.
