Backup and restore worlds in Minecraft Windows 10 edition

Here is how to backup and restore your saved games or worlds in the Windows 10 edition (from the Windows store) of Minecraft. It is actually pretty easy once you know where the save games are, although it would be nice if they would save to Onedrive or cloud so that they were automatically backed up.

To backup:

  • Open %userprofile%\AppData\Local\Packages\Microsoft.MinecraftUWP_8wekyb3d8bbwe\LocalState\games\com.mojang\minecraftWorlds
  • Copy the folders in here e.g. to your Onedrive. These are your worlds.

To restore:

  • Install Minecraft on the PC
  • Login using the same Microsoft account
  • Open the above location, and copy the folders in there
  • Now just run Minecraft and you should see your worlds

Running Homeworld on Windows 7 or Windows 8 widescreen


Today I was feeling nostalgic and decided to replay the classic original Homeworld game, which was released in 1999. I remember the graphics, story and music with such fondness, I thought I would see if it runs on Windows 8.1 x64 with an Intel HD 3000 onboard graphics card. It is still great, this is how I got it running:

  • Download Homeworld from (abandonware)
  • Extract using 7zip, and then extract the .img file using WinImage (I was unable to mount this directly)
  • Install the game, which takes about 30 seconds on an SSD
  • Install the patch included in the download
  • Find a no-CD for the game, assuming that you do not have the CD 

Now, on running this game, and enabling OpenGL mode, I had several issues:

  • There was severe screen flickering when using OpenGL
  • Resolution was not widescreen
  • Blackscreen on startup 

These issues were resolved as follows:

Screen Flickering

  • Add /triple to the shortcut to start the game. If this keeps happening, try removing /triple again.

Resolution fix

  • Edit HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Sierra On-Line\Homeworld
  • Check screenHeight and screenWidth to match your resolution 


  • Set compatibility mode to Windows 95 or 98 

Note that d3d mode can be used, but I found that this has bad mouse lag in the Build menu. I found some other tweaks online and eventually used the following shortcut:

C:\Sierra\Homeworld\homeworld.exe /triple /heap 1073741824 /enableSSE /disableAVI /pilotView

Note that the pilot view switch gives lets you ride on the back of a ship by pressing q.

I had a lot of issues switching between display modes. The easiest way to do this is via the registry. Just switch these 2 registry keys around, for OpenGL:


For Direct3d:


However, d3d takes some time to show the menu, and then has lag in the build menu which makes it unusable for me. OpenGL has no issues other than some initial flickering when first loading. It is basically a question of messing around with the registry and shortcut until you find the optimal config.  I would also suggest, if you run into issues, delete the entire key at HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Sierra On-Line\Homeworld and run it again. It will go back to defaults, switch to OpenGL, and then set the resolution again in the recreated key.

Reinstalling Windows and keeping Steam content without backup

Today I discovered somthing extremely handy if you are a Steam user for games on Windows. This does require that you already store your steam games on a seperate partition or disk to your OS installation. I do that to keep all the games off my rather small 128GB SSD drive which contains just the OS. If you don’t have steam on a seperate drive, you would have to backup all the content in Steam (right click on a game and choose backup) and then reinstall Steam on another drive, e.g. D: instead of C:.

If you have installed Steam on another drive, you are in luck. All you need to do is reinstall Windows (clean install is fine, format the C: drive and install a fresh copy), then you just download and install Steam into the same location it was previously. Lo and behold, Steam sees all your games and steam apps, and when it starts up you will see all your games ready and waiting. Pretty neat huh? If you buy games exclusively through Steam, this makes reinstalling the OS much easier. I would recommend that you backup your Save games just in case.
