Seems to be a problem with the WDDM driver not being installed with the Windows 10 update, seems Parallels have known about this since June, think they could have put a new KB up, here's the old one.

I tried the method above but couldn't upgrade from within either WIn 7 or 8.1. I had to download the ISO and then install a new VM with Parallels BUT Windows 10 is incompatible with Parallels 10 in Coherence mode! A new Parallels update for Windows 10 is needed urgently.

 

This worked for me after two tries, thanks! Any idea now if we can do a fresh install? Now if only I could get the START menu to match my surface!!

 

Same issue here and report (No 70596175) created too. So disappointed with parallels right now.

 

I got the same error message....
Guess this will be solved in Parallels 11.
But that does not yet exist....

 

After trying all all of the suggested fixes yesterday, JimC2's solution worked (finally) and all is well. Thanks for the tip!!!!

 

I have done this, but windows 10 did not install properly.

 

The only thing I had to do was increase the amount of RAM for the VM.

 

Hi Maria,

Yes It works but with flaws. For instance, Control Center does not update the logo for win 10. In my case still shows the win 7 logo.

When should with have a transparent and user friendly way to update a VM to win 10?
Kind regards.

 

Maria, I followed the instructions in that KB and this was what I got, on both my machines running the fully updated Parallels 10

 

Close this Window? I'm attempting to upgrade from within both Win 7.1 and 8.1.

 

As mentioned I got it installed successfully, but for some reason once in Windows 10 and running applications, it causes my entire mac to reboot and crash - has anyone else experienced this?

So I have a question. I have Parallels 10 (latest build) and I am trying to download the ISO file from Microsoft. The media file downloads and then I click on "upgrade", but the download never starts. I start at 0% and stay there for over a day before killing it. It downloaded and installed on my stand-alone PC is less than an hour. Has anyone else encountered this? Any ideas?

 

I tried yesterday with the download and created USB bootable. Installed from USB and had the same issue with window not activating. Today I ran the download tool again and then instead selected "upgrade this computer" and the install worked and Windows 10 is now activated. I think if you use the ISO, it doesn't activate it with you existing product key and that why it mentions that you will need your key to activate. But it looks like there is a bug with the ISO/USB install that doesn't allow for activation of Windows after install.

So what happens when it doesn't work. Are you able to go back to what you had relatively easily? Im using 8.1 and I am an amateur at best.

I have the icon for windows 10 upgrade and parallels 10.2.2. Should I even attempt this? Or should I wait until things are a little more stable?
