Before you proceed, you should ensure that you have updated your Windows 8.1 and Windows 7 with all the available Windows Updates. Having done this, go the list and see which scenario or suggestion/s may apply to you.

1] Check if your PC meets the minimum requirements to download or install the Windows 10 upgrade.

2] Disconnect all external USB’s, accessories, media, extended display cables, Wi-Fi adapter card, etc, from your computer.

3] Disable your firewall, antivirus or security software, VPN, temporarily. You may also temporarily uninstall such software like Disc Burners, Defragmentors, Optimizers and all programs which start up with Windows, as some of them have been reported to create issues. Incompatible application installed on your PC could be blocking the upgrade process from getting completed. Do a thorough check that any incompatible apps are uninstalled and then try upgrading your PC.

4] Use Disk Cleanup Tool to clear up disk space. This may help you upgrade Devices with less free disk space to Windows 10.

9] Many a times, an update may fail to install in the first instance, but for some inexplicable reason, succeeds in the 2nd or 3rd try. So try a couple of times.

10] Change your Disk partitions from Dynamic disk to Basic disk and see if that works for you. Backup your data first and be caredul if you decide to consider this suggestion.

11] If you are unable to upgrade to Windows 10 via the Get Windows 10 app, use the Windows 10 Media Creation Tool to install Windows 10.  You may also upgrade to Windows 10 using ISO.

All the best!
