Scenario
You have attempted to upgrade to Windows 10, perhaps with the media / download tool however none of the upgrades are successful.
You may be experiencing one or more of the following symptoms:
- “Upgrade this PC now” gives the disappointing “Something happened” error message
- Creating a USB or ISO image is unsuccessful
- You may receive a message box saying “Setup has failed to initialize the working directory”
- Windows Updates for “Upgrade to Windows 10 Pro” has repeatedly failed
- User anger and frustration at the implication “Something happened” but in reality absolutely nothing happened and you have to start again!
Possible Cause
I’ve seen this problem occur when the C:\ drive on the computer being used is low on disk space.
The upgrade process requires approximately 3GB to store upgrade sources, however the actual upgrade and/or creation of an ISO image requires more space. Ensure you have a minimum of 10GB space free on C:\
If you’re unsure where your disk space is tied up, I recommend the free and open source tool WinDirStat to help you visually find used space in unexpected locations.
Did this help? Let me know in the comments.
