Hi there,
The CU version is actually v1703, not v1701. Small detail. And you're right about the AU (v1607). What you do need to know is that I've done about a dozen W10 upgrades from earlier windows versions, W7/W8x and W10 v10240, v1511, v1607 to the current v1703 (CU) mentioned. In all but 1 case (which interestingly enough just occurred for the first time on a Customer laptop this week!), you cannot upgrade directly from any of the earlier W10 versions starting with the RTM version released on July 29th, 2015. So, in 99% of the cases, you most likely have a hardware compatibility that exists, or an app that isn't liked by the new v1703 version, or a driver issue. When you attempted to run the upgraded to v1703, did you remember to run the all important
W10 COMPATIBILITY TEST? If not, you can try it again using the following instructions here:
Get Compatibility Report for Windows 10 in Window 7 and 8.1
Remember, that even if your Compatibility Test passes after you resolve all found issues, that still doesn't guarantee success. You also have to go visit the computer manufacturer's website, and verify they have driver support for your exact machine, a serial number check is best, to see if the manufacturer has driver-level support on their website and new drivers, especially BIOS, Chipset, and GPU support for your aging hardware. If they don't, it's unlikely that your v1703 upgrade will run to completion at all.
The good news, is that you can use the free
W10 UPGRADE ASSISTANT to help you attempt the upgrade if your machine meets the above requirements. However, as we help hundreds of people here every month with the same problem you are having, we have found that in all but the one case above, (at least for me), you cannot upgrade this way
AUTOMATICALLY, you have to use the
W10 UPGRADE ASSISTANT to get from your old W10 version to the newest v1703 CU version.
With all of this being said, if you get to this point and
STILL cannot upgrade to v1703 CU, you're best bet is the
CLEAN INSTALL using the Microsoft MCT tool available here:
Link Removed
This allows you to download the latest
W10 ISO FILE directly from Microsoft (safest!), and burn to either DVD or USB media. The most important challenge you have here is to ensure that
YOU HAVE FIRST BACKED UP ALL YOUR PERSONAL DATA (LIBRARY FOLDERS) TO EXTERNAL MEDIA IN ORDER TO AVOID IRRETRIEVABLE DATA LOSS IN CASE SOMETHING GOES WRONG!!!
In the vast majority of cases, the Clean Install is your best bet, assuming that you've thoroughly tested your hardware before attempting to do so. If you have not done this, you can pay a Tech to do for you, or if you are a DIY guy, take a look at my excellent and free
TROUBLESHOOTING GUIDE available here:
Windows 10 - Unclickable Task Bar
Basically, I'm telling you that the automatic update for W10 to get your computer to run the latest and greatest version of W10 has not worked for the most part going back nearly 3 years on the pre-release Tech Preview editions of W10, and it got no better on the RTM versions in 2015 either. Most folks are not aware of this history if they don't repair computers for a living. If you think I'm blowing smoke up your skirt here, please fee free to search the W10 sub-forums here for posts on W10 upgrade failures, as well as on the Microsoft Community Forums (including the Insider Hub forum too).
Let us know how you get on or if you have any further questions. We are here for you 24x7x365.
Best of luck,
