Cannot Update Windows 10 to 1903: Error 0x80240034

Hello, I was recently trying to get Visual Studio for a C++ class I have, but it refused to download saying I needed to update to the latest version of Windows 10. After checking Windows Update, I realized that it is only version 1709 and hasn't been successfully updated in ages. Even though 1903 is the latest update, for some reason Windows Update keeps giving error messages of failing to update to 1803, which is odd. The error code was 0x80240034. I tried using DISM and SFC but SFC says it found zero corrupted files to fix. I have tried using Windows Update Assistant, the Media Creation Tool, and manual update through an ISO on a USB drive. All failed during the installation and reverted any changes. I am at wits end trying to find a working solution to this, and refuse to do a clean install as I like how everything was set up by the place I bought my gaming laptop from. Any assistance would be greatly appreciated, as other successes for users with similar issues did not work for me.

Thank you in advance,

Anthony

Hi,

Try updating to 1903 using Media Creation tool and if it fails, share the logs.

The fastest way to get the upgrade is through Media creation tool or ISO file.
Please download Media Creation Tool from the link below and select Upgrade this PC at the first screen.

All steps, including upgrading using ISO file and Media creation tool, are covered here:

Meanwhile, if the update fails with MCT as well.

Let us check the Installation log to find why the update failed. Please share the logs as mentioned in this article. You should use a File sharing service like Onedrive or Media Fire to upload files and share the link in the next reply.

The Panther logs. Files named Setupact.log and Setuperr.log from the following path C:\$Windows.~BT\Sources\Panther

The Rollback logs: These usually are created if Windows Update rolls back. Files named Setupact.log and Setuperr.log from the following path C:\$Windows.~BT\Sources\Rollback

[Only if the error code is 0xC1900101-0x30018] The Device Install Log from C:/$Windows.~bt\Sources\Rollback\setupapi\setupapi.dev.log


As the log size might be large consider zipping before uploading.
