After the release of Microsoft’s Insider Program for free installing of Windows 10 Technical Preview, many Windows users were excited to join it. But, upgrading to the new system brought new bugs and errors, and today we’re going to solve one of them, more precisely the 0xc1900101 0x20005 error.

After installing Windows 10 Technical Preview or upgrading to Build 9860, some users are constantly getting the 0xC1900101-0x20005 error. This was frustrating for many of them, because they thought that it is some kind of dangerous error, but don’t worry, it’s not. All you have to do to prevent this error from showing up is to clear some disk space. You can delete some software you don’t use, or some old movies and music, it is completely up to you.

The reason why this error shows up is that Windows 10 Technical Preview needs 16GB of free disk space, and if you have just a little bit more than 16GB of free disk space, you won’t be able to install new apps or programs, which your system doesn’t like and you’ll get this error message until you free some space. I can’t tell you how much free space you exactly need, because it depends on the size of your hard drive.

Another reason for getting the error 0xC1900101 – 0x20005 is that your computer is not fully compatible with the new Windows, which might be the case if you’re using an older machine. So, before you decide to download Windows 10 Technical preview, make sure that your computer is completely compatible with it and that you have enough free disk space.

Just as a reminder, here are the system requirements for Windows 10 Technical Preview:

1 GHz processor with SSE2 support, NX and PXE
1 GB (32-bit) and 2 GB (64-bit) RAM
16 GB (32-bit) and 20 GB (64-bit) disk space for a clean installation
80 GB (32-bit) and 130 GB (64-bit) disk space for the upgrade
GPU-compatible with DirectX 9

If your computer is fully compatible with Windows 10 Technical Preview and you have enough disk space, but you still get this message, please let us know in the comments, because we would like to help you in solving this problem.
