What should I do if Win7/8 encounters problems when upgrading Win10?

Come together today, when Windows 7/8 upgrades Windows 10, what should I do if I encounter problems? Let's take a look at the following small series!

Error code C1900101

The problem encountered during the upgrade process is "WindowsUpdate_C1900101" or "WindowsUpdate_dt000", usually the security software installed in the system by the computer. Caused (I think the reason for the failure to upgrade Win10 with 360 and Tencent in the past is here), so it is very simple to solve, you can disable these services directly.

Enter msconfig after Win+R, disable all third-party startup items in the computer "Startup", switch to "Services", check "Hide all Microsoft services" after After all the services that can be displayed are disabled, you can upgrade Windows 10 smoothly.

Error code C1900204

If you encounter the above error code, it proves that the existing system cannot be upgraded normally through WindowsUpdate function. It is recommended to be on the official Microsoft website (http://www). .microsoft.com/en-us/software-download/windows10)Download the Windows 10 ISO image upgrade installation.

Error code 80070015

This code is more common, and it is the first upgrade error that was first simulated on a small computer. It may be that the upgrade file is damaged by the server or the network. . Go directly to “Control Panel - Administrative Tools & rdquo;, double-click "Services", click the "Name" column headings to sort the names in reverse order. Find the "Windows Update" service, right click on the service, and then click “Stop”.

After the C drive Windows folder, find the SoftwareDistribution folder, empty “DataStore” and “Download” folder (with hidden files). Then follow the first step to restart “Windows Update" in the "Services" and re-download the upgrade file.

Error code 80240020

If you encounter this code, directly press the above 80070015 processing method, clear the SoftwareDistribution folder, then start the administrator mode command prompt, enter

wuauclt.exe /updatenow

Command (with spaces before /), wait for peace of mind.

Error code 800703F1

Start the command prompt in admin mode, enter

net stop wuauserv

, then SoftwareDistribution under Windows Rename the folder to SoftwareDistributionOld, then continue typing at the command prompt.

net start wuauserv

Close the command prompt and restart your computer to securely upgrade to Windows 10.

Error code 80240031

The culprit causing this code should be caused by the Windows BITS service setup problem (the small series is not very sure, but it will be OK if it is tossed). Use Win+R to call up the run window and enter services.msc, double-click to open the "Background Intelligent Transfer Services" service. Click the “General” tab to ensure that "startup type" is "auto" or "manual". Then click the “service status” button below.

The same steps can be used to enable the four services "Windows Installer", "Cryptographic Services", "software licensing service", and "Windows Update".

The above 6 are common error codes when upgrading Windows 10. After repeated tossing, you can only reproduce some problems. If you have any questions, Xiaobian must solve them in time.
