Hi abdulahi abduwali,

Welcome to Microsoft Community.

Let me help you troubleshoot the problem about Windows 10 upgrade failure.

With the error code 0xe0434352, run the followping commands to fix it. Run Command Prompt as an administrator ("Win" logo key + "Q", enter "cmd", select "Run as administrator"), and enter the following commands one by one. These commands require network support, please keep your network stable and smooth.

for %i in (%windir%\system32\*.dll) do regsvr32.exe /s %i
for %i in (%windir%\system32\*.ocx) do regsvr32.exe /s %i
DISM /Online /Cleanup-image /RestoreHealth
sfc /SCANNOW

Then I suggest you use MCT(Media Control Tool) to create a USB boot disk or download the ISO file, then try to boot from the boot disk, and then execute the installer. Because of the large differences between Windows 10 and Windows 8.1, unexpected errors may occur during the in-place upgrade process.

Step-by-step steps to make a boot disk in MCT

1. Back up your data,
2. Prepare a flash driver with at least 8GB (Pay attention to backup data, because creating a boot disk will erase all data of the flash driver). Then operate it on another Windows computer.
3. Visit Download Windows 10 (microsoft.com) **** and click "Download Now" to download MCT (Media Control Tool)
4. Run the MCT, select "Create installation media (USB flash drive, DVD or ISO file) for another PC”, and then choose Language, Version, Architecture (if you are not sure about these, choose "Use the recommended options for this PC"), then select "USB flash drive" in the "Select Media to Use" interface, then make a boot disk.
5. Then boot from the USB flash drive, and execute the installation program.
