Windows 10 April 2018 Update: Here's what you can expect
As I've noted in the two previous installments in this series, Windows 10's Hyper-V platform is the ideal way to test-drive a new feature update before trusting it to production hardware.
If you've been following along, you've enabled the Hyper-V features and created your first virtual machine. Now it's time to fine-tune that virtual machine for proper performance.
The most important virtual machine setting is the one that assigns physical memory to your virtual machine. The more memory that VM has, the more you can do with it. And by taking advantage of a feature called virtual memory you can avoid starving the host PC of the memory it needs to do its own work.
Open the Settings dialog box for your virtual machine and click the Memory tab to see and adjust this allocation.
I recommend you pay close attention to two settings in particular.
First, decide much memory to assign to the VM. Using the Quick Create wizard automatically assigns a default value of 2048 MB (2 GB) of RAM, which is not enough for acceptable performance.
On a system with at least 8 GB of physical RAM, I recommend setting a minimum of 4096 MB (4 GB) here. If you have 16 GB (or more) of physical RAM and you plan to use the VM to simulate real working conditions, consider assigning it 8192 MB (8 GB).
Next, decide whether you want to use dynamic memory. When you select the Enable Dynamic Memory check box is selected, your VM starts with the amount of memory you specified above but then adjusts the actual memory allocation to what it needs.
(If you choose not to enable dynamic memory, Hyper-V assigns exactly as much physical RAM as you specified above. That option might be acceptable if your host PC has a ton of RAM (32 GB) and your virtual machine only needs a fraction of it.)
Set the Minimum RAM and Maximum RAM values accordingly. On a system with 16 GB of physical RAM, you might set these values to 4096 MB and 8192 MB, respectively. That prevents the system from lagging when it's under memory pressure.
Windows 10 tip: How to enable Hyper-V and create virtual machines
Every business edition of Windows 10 includes a full-strength virtualization platform, Hyper-V. If your PC meets the requirements, you can begin creating virtual machines for testing software and services without risking your daily productivity.
Windows 10 tip: Quickly create a virtual machine to test new features
In recent feature updates to Windows 10, the Hyper-V Manager includes an option to create a new virtual machine from a single dialog box. Be sure to check these four settings before you use this one-click option.
Windows 10 tip: Turn off Cortana completely
In the Windows 10 Anniversary Update, version 1607, Microsoft removed Cortana's on-off switch. But it's still there, if you know where to look. Use this tweak to make Windows search strictly local.
Windows 10 tip: Shut down OneDrive completely
In Windows 10, OneDrive is built in. The connections are so tight, in fact, that OneDrive has its own node in File Explorer, with no obvious way to remove it. But the options to disconnect OneDrive are there if you know where to look. Here are the full instructions.
Windows 10 tip: Repair your Windows 10 installation
Performing a clean install or a reset means you have to reinstall apps and desktop programs and start over with settings and preferences. If you suspect Windows has become damaged, there's a less drastic solution: Run Setup to repair Windows. Here's how.
