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.
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”
You’ll need administrator privileges to use these command. You can also run them from a command prompt in recovery
Turn off Encryption
manage-bde -off C:
Change C: to the drive that has BitLocker on it. Check with the status command. May not be C if your in recovery. Also note that after the encryption is turned off it takes awhile to decrypt. Check with status command
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
