Remove hiberfil.sys

The hiberfil.sys is created and used when hibernating in Windows. Sometimes can be needed to help shrink the space on a drive.

Launch a command prompt with administrator privileges.

You can hit Windows Key + R, type in cmd, and hit Ctrl + Shift + Enter together. It’ll ask you to verify that you want to launch it. Hit Yes.
Alternatively you can search for the Command Prompt, Right click on it and Run as Administrator

Turn Hibernate off

powercfg -h off

A reboot should remove the file. If not you should be able to delete it. It is on the root of the drive, but you’ll need to enable hidden files and disable the “Hide protected operating system files” to see it.

You can turn it back on by changing off to on

powercfg -h on

Windows 10 – How to “fully” shutdown

Windows 10 by default does a hybrid shutdown which is supposed to make it quicker to start back up.

To fully shutdown you can hold the Shift key down while clicking the shutdown button.

Side note. A Restart will do a full shutdown before starting back up.

Boot up radio in tftp mode by pressing the reset button for ~20seconds or till you get the crossing blinky lights.

Can’t set default app for .blend file on Windows 10

Problem: Can’t set default program for .blend files to Windows store version of Blender

Usually is not a problem as you’ll get asked if you want to set a default program. When you hit yes, blender does not show up in the list of apps. That wouldn’t be a problem, except Blender is from the Windows Store, so there is no launcher in the ordinary places.

Resolution: Install regular Windows installer from Blenders website.

Other Info

Not sure if the issue is with the Store or Blender. The .blend file type does not show up in the Windows Settings under “Apps -> Default apps -> Choose default apps by file type” and Blender doesn’t show up under “Apps -> Default apps -> Set defaults by app”

Microsoft Office Programs laggy when dragging with mouse

Problem: When clicking and dragging Office Programs by the title bar, the window is slow to move and respond to the mouse location.

Resolution: The problems appears to be related to the USB polling frequency for the mouse. Look at the mouse settings and try reducing the polling frequency. And/or try another mouse.

Windows 10 – Super slow copy speeds

It looks like the Windows Defender Real-time protection can cause issues when trying to copy files on a local drive even if the drive is an SSD.  Typically a copy seems to start out great, but then slows down to a crawl less then 1MB/s copy rate.  Probably has to do with Defender having to scan every file as it is copied.

To fix/increase the copy speeds you can turn off Real-time protection.

To turn off Windows Defender Real-time protection, open up Settings > Update and Security > Windows Security > Virus & threat protection “That should open up the Windows Defender Security Center” > Virus & threat protection settings

Now Turn Real-time protection off.
