How to fix the windowsupdate_c1900101 error that has been prompting me from the past week or so? This error was showing me whenever I try to update my PC to Windows 10.
So to perform a clean upgrade of your PC:
• Keep all your drivers up-to-date.
• Disconnect all the devices that are currently connected – Even any kind USBs to avoid distortion while doing this process.
• Temporarily disable all the kind of security system that is currently active like anti-virus and firewall.
• Now go to the clean boot state to determine any interfering programs before upgrading your PC.
• If not you can manually Upgrade your PC either by going for CD installation or through the official website.
