What should I do if Win7/Win8.1 fails to upgrade Win10? Upgrade Win10 installation failure solution

What should I do if Win7/Win8.1 fails to upgrade Win10? Many Win7/Win8.1 users encountered an "installation failure" problem during the official upgrade of Win10 today, which caused the upgrade to fail. The following Pepsi network Xiaobian share the Win7/Win8.1 upgrade Win10 failure temporary solution, friends who have problems can refer to the next.

The user of the organic wisdom downloads the temporary folder "C:\\$Windows.~BT\\" (hidden system folder) from Win10 installer to other partitions, and starts the source. The setupre.exe program in the folder can be installed normally.

Note that if your "C:\\$Windows.~BT\\" folder is not complete, it is likely that the download has not been completed. Note the Windows Update ID on the right side of the taskbar. If it exists and prompts you to download the percentage of updates, you should not do this. After the prompt disappears, entering the folder will reveal that the contents of the file are very similar to the Win10 system image.

But there are also users who say that the contents of the "$Windows.~BT" folder will disappear in some cases, which has a lot to do with its "temporary" attribute. The root cause of this problem is that the system believes that the file in the folder has "completed the mission" and therefore deletes the content, but from the feedback of "installation failure" and other issues, this is obviously a serious mistake. Therefore, in order to prevent the abnormal problem caused by this folder property problem, you can consider putting the files in the copied folder into the normal folder or changing the folder properties after copying. Remember, don't make any changes to the original "$Windows.~BT" folder, so as not to affect the normal upgrade channel.

The original 6GB or more folder is only 140MB inexplicable
