AND THE WINNER IS SLARTABARTFAST!!!!! You, my man, RULE! LOL!
I had no idea that Internet Explorer was hiding in Windows 10! I followed your instructions. I had to let it install the Windows Update Catalog and after doing so, up popped on the screen the drivers I have been chasing ever since 10 was installed!
Many thanks to you and I hope that someday I can repay the favor. This needs to be a sticky at the head of the forum. I know that many of us will benefit from this fix. Thanks, again.

Hi there

so, can you share it with us? (the driver)
thank you

I am sad to say we are still at the mercy of Microsoft! I downloaded those cabinet files and they are the drivers but there is no installer with them. Can someone tell us how to install these drivers? They come as a cabinet file that has to be extracted. I did that and while the drivers were there there was no installer to be found! Anybody have an answer? Otherwise, I guess I'll have to use the 8.1 driver hack.

Looks like you have to "stage" the driver and pretend you are running Windows Update:
 
Installing drivers

• Open a command prompt from the Start menu.
• To extract the driver files, type the following command at the command prompt, and then press ENTER:expand <CAB FILE NAME> -F:* <DESTINATION>
• To stage the driver for plug and play installation or for the Add Printer Wizard, use PnPutil as described in the following Microsoft Knowledge Base article:937793 The staging and the installation of driver packages by using the PnP Utility (Pnputil.exe) in Windows Vista
  Note To install a cross-architecture print driver, you must already have installed the local architecture driver, and you will still need the cross-architecture copy of Ntprint.inf from another system. For more information, click the following article number to view the article in the Microsoft Knowledge Base:952065 You cannot install third-party printer drivers for cross-architecture support in Windows Vista or in Windows Server 2008

  I'm having my own issues with my UA 25-EX. Windows Update won't grab a Win 10 driver on my newer DAW yet on my old DAW there are no issues. To do the Win 10 upgrade from Win 7 I have to unplug my cd drive. Go figure.
  

Would appreciate any info if you can get this to work (or not work).

this is really ridiculous
this can not be legal, they must make available the drivers for win 10, period!
this is a flagship product, even if it was a toy.
it's ok that can use this method for some people installing the drivers, but they must give the drivers to all if they want. for example, I turn off the automatic win update and drivers update, I use windows like this if I want.
We must have an alternative method to install (like offline method). we need this drivers Roland, or I will return this product! what a shame!!
people here trying to get the driver (it's not our job doing that) please ask roland to give us the driver, they got to give us
I already asked at roland us and roland uk
this is so ridiculous Roland!!
waiting (six days left to return this product)

Many devices, today, ONLY have the Windows "plug and play" option for drivers - not just Roland.  This is really better, in Roland's case, as they kept issuing drivers for specific OS's rather than a general driver that will work on multiple OS's.  The drivers were actually the same just coded for a specific OS.
 
There is a method, and its been referenced on this thread about how to modify (hack) the Win 8 drivers so they will work on Win 10, if you must have a physical driver.
 
Otherwise return the unit, since you still have the option, and find something that satisfies your specific requirement.

you're wrong, i don't know any brand that don't make available drivers, unless they didn't support windows 10, or if it is class compliant usb devices, that's another story, but they have, so Roland make it available for download!

this is utterly ridiculous

I had no problem extracting the cab files! You simply right click and extract here. There is no installer! Just the driver files themselves. That was the problem. As I said, Fireberd and a couple of others were nice enough to come thru with a hack that allows us to set the 8.1 driver to install as a 10 driver. I have done the hack but have not had an occasion yet to try it out. I will keep you advised if that happens. Otherwise, I am firing off another request to Roland to post these drivers. I'm sure they are going to say that Microsoft is probably responsible for those drivers now and we'll play the shift the blame game! Oh, well. Ain't technology fun, students!

got a reply from roland uk, and they sent an email to their team in japan (headquarters, I guess), and think they will send me the win 10 drivers then!
fingers crossed

@Sidroe, after the "extract here" for the drivers did you do anything? Did you have to do "Update Driver" and point that where the driver was extracted to or did Win 10 find the driver with no other action on your part after you extracted?
 
These hacks shouldn't be necessary.
