Updated on 7.3.14 We dedicate another, hopefully last article on installing Windows 8.1 trying to give all the help possible to solve problems and update errors .
Many people have tried to upgrade to Windows 8.1 without success, because they have not found it, due to licensing problems or other reasons.
The thing is, Microsoft distributed Windows 8.1 for free to regular Windows 8.1 users, but didn't want Windows 8.1 to be downloaded to install it from scratch.
Given the numerous requests in the guide on how to download Windows 8.1, update or make a new installation, I think it is worthwhile to provide all the information that can be found to help those who have difficulties with the Windows 8.1 update .
1) Why I can't find the Windows 8.1 update in the Store "> Microsoft support page lists some reasons, but not all, for which Windows 8.1 is not available on the Store.
The main one is that Windows 8 systems installed with Volume Licensing are not supported and this includes some OEM installations.
To check the Windows 8 license, run the command, always in the Run window, slmgr.vbs / dli
The other reason concerns the preventive installation of all Windows 8 updates, to be done in Windows Update.
Possible solutions are collected on this forum page, in English.
2) The update starts but the installation of Windows 8.1 cannot be completed
Even if you do see the 8.1 update in the Windows Store, this does not always work.
It may be helpful to follow this procedure where it is written to open a DOS command prompt, run two commands: net stop wuauserv and net stop bits, go to the C: \ Windows \ Software Distribution folder and delete all the content and then run the two commands net start wuauserv and net start bits .
3) Updating Windows 8.1 causes problems on some drivers.
In some cases, Windows 8.1 does not install due to a driver problem that causes the update to fail with error type 0xC1900101 - 0x40017 .
To solve it may be enough to update the drivers, otherwise you just have to read the forum page that documents this error and try to understand what is wrong.
4) After installing Windows 8.1, my USB disk disappears or the file transfer stops unexpectedly .
On this page there is support for those who have problems with the USB ports after the update while in this there is the solution for a similar problem with the SuperSpped ports of Asus computers
5) How to update or install Windows 8.1 without using the Windows Store
If you have a regularly purchased license of Windows 8 with product key, this article explains how to download and activate Windows 8.1 with the Windows 8 product key .
6) An update error message can be " Unable to update to Windows 8.1 .... ..... This could be because the Program Files or Users folder is on another partition "
The solution is in this article.
7) The Secure Boot is not configured correctly. Build 9600
This Secure boot problem can be solved easily by installing a patch
8) With the update of Windows 8.1 the computer restarts and shows the black screen .
This problem seems to have been resolved on the Microsoft forum and concerns the presence of Antivirus or incompatible Firewall programs.
