I have one Windows 10 guest from last many years, upgraded through VirtualBox versions 5, 6. Recently I upgraded VirtualBox to 7. While Windows XP & Oracle Linux guests automatically resized the display on host, Windows 10 guest was adamant. Uninstalling and installing the guest addons didn’t help.
After scavenging through few posts over VirtualBox forums, came across one of them discussing about fixing the resizing issue by choosing “VBoxVGA”, though it was not supported. I decided to give it a try and Windows 10 guest resized the display when I toggled the “Auto-Resize Guest Display” from the view menu.
Then I shutdown the guest, changed the Display back to “VBoxSVGA” & the guest allowed me to resize the display using View menu & subsequent restarts were resizing the guest display as expected. However, there were times when I had to manually adjust the display size. Hope Oracle fixes this issue in coming releases.
Greetings! Yes, I know it was a long break. Trust me, I wanted to post many things, couldn’t as I was too busy (doing my actual job, traveling etc ;) )
Anyway, Windows 10 is never packed with less surprises. Recently I was going through a 4K video clip with multilingual audio tracks & realized that the much celebrated VLC player cannot play it, when the default Movie & TV windows app played the clip without a single break or lag. However, as soon as I tried to switch the default language from “Arabic” to “English” I started getting the error “The device is being used by another application” & the app stopped playing the video (lands on the gallery actually)
I was lucky enough to land on a page with correct solution. https://blog.pcrisk.com/windows/12516-how-to-fix-the-device-is-being-used-by-another-application & “Disable Allow Applications To Take Exclusive Control Of This Device Option” section helped me to finally get over with this major annoyance. Not just that, once done, the app remembers the audio track that you selected & plays the same when you open the same video clip next time! unlike VLC player.
If you landed on this page, looking for a solution, please go through the blog from pcrisk.com & they have multiple solutions to this issue and one of the solutions listed there should help you also.
We know it is too early, still as usual we are kicking in once again trying to install Oracle 10g onwards databases on an OS that’s in the early stages of testing/improvements.
You may safely ignore the warnings (if any) and proceed with the Installation. Please note, as usual we warn you not to install unsupported databases on newer Operating Systems as you may risk with your valued data. Below, few screen shots from our installation attempt which was successful.
You will be prompted to install .NET Framework 3.5 (That includes .NET 2.0 and 3.0), and we suggest you install it for better stability of the database
This is our first post after months long break. As Microsoft has released the technical preview for their forthcoming OS “Windows 10” we are once again engaging ourselves to try out “Uncertified” Oracle products over a possibly half cooked OS in the preview state.
We will try explain how to install Windows 10 Technical Preview on VirtualBox in next few steps
Windows 8.1 comes with Hyper-V enabled default. If you are planning to try out the 64Bit version of technical preview, make sure you disable Hyper-V from “Windows features”
Uncheck the Hyper-V & restart the computer when prompted.
We are sure, if you are an enthusiast wanting to try out the preview, you are already a half geek, who knows how to signup something very straight forward like “Windows Insider”
Download your choice of technical preview, 32Bit or 34Bit ISO file. The file is on disk is 3.81GB, so if you have a slow connection, start download, have a nap. We are on a 12MBPS fiber connection and it took around 50 minutes for the download to finish!
Start Oracle VirtualBox now
Create a new Virtual Machine (Follow the images)
Based on available memory on your computer, setup the maximum memory you can allocate for the VM. We suggest a minimum 4GB for better performance
Create a virtual drive now, minimum 20GB is recommended
Complete the Virtual Disk creation based on your preferences (eg: location, VDI or VMDK)
We just created a new VM, however remaining are few more settings. Let us analyze what kind of choices were made by VirtualBox for our new VM until.
General
System
Change the number of processors to 2, if you have more cores.
Finally load your ISO file to the IDE controller.
Save the changes by clicking “Ok” and let us start the VM finally, thus initiating the installation process
Based on the language selection you made prior downloading the ISO file, you will be prompted to start the installation after couple of minutes waiting
Follow the prompts and Select “Custom” installation while prompted.
Rest assured, wait for the installation to complete.
We opted to go with “Express settings” for the installation
You will be asked to sign in with a Microsoft Account next, just select “Create a new account”, that will allow you to “Sign in without a Microsoft Account” option
Once a local account created, you will go through the same Windows 8/8.1 setting up procedure, stay calm
That’s it folks, now you have completed the installation of Windows 10 Technical Preview using Oracle VirtualBox!
