Build 18850 - Skip Ahead 20H1 - Unable to Open Any OneDrive Files

Have you considered going back to the previous version of Windows 10?

Other than that have you set up system restore? Or have you any System image back-ups?

Please tell me that this is not your main computer and that you have backups for all your documents?

Thanks both for the comments .. to allay major fears, this is not my main PC but is important to me and I'm not enthused about immediately junking everything this early. My Insider Desktop running 18351, (19H1), is fine so I know that the OneDrive files are intact and available if I can just get the OS on the Insider Laptop operating.

Ref the suggestion from Davy-Delliot does "Go back to a previous version of Windows 10" simply re-install OS version 18845 without impacting the "structure of the PC"? I don't want to trash everything. (Reason for question is that I have never used this option previously especially not in Skip Ahead versions - been "lucky" up to now)!

Hi RogerW2,

In this instance the OneDrive folders are not empty, all the files are still intact, (as far as I can tell using my Desktop PC), it's simply that the programmes on the PC, (Office &c), simply cannot read them and see that they are unavailable?

I can't establish whether this is because I am not properly signed into OneDrive or because of some other issue. (The only thing that changed was the OS from 18845 to 18850 so I see that as being the protagonist here).

If I use a browser and sign into OneDrive I can see my "on-line" files and directories and can open them using the on-line readers however of course the formatting is gone. (I use Office 2016 Desktop and not 365 though the same applies to non "Office" programmes like pdf's and JPEG and PNG files). 

Does going back impact the structure, yes and no.

Plus don't worry about losing your skippy status just use the regedit posted in the Forum. Many have used it and got back in successfully.

I had a problem with One Drive a few builds ago. After the build installed I had a coloured mark on the Cloud icon. It transpired that One Drive had lost my MSA and I had to re-authenticate my account. In the end I had to sign in again and I ended up changing my password I believe.

Hi DD, 

Thanks for the additional detail .. As the OneDrive Files are intact in the Cloud the "data" is not a real concern however, in your experience did the "Step-back" lose any other programmes you had installed such as PhotoShop, Adobe Acrobat, QuickBooks and so on or did they stay as was? 

I wonder whether I might just sit tight and wait for the next "update" to 18852/3/5 whatever comes next!

I am assuming that what has happened here is that the OS installation process itself "glitched" as unusually, the actual post "Download" installation activity stretched to around eight hours when of late, pretty much all install activities have been no more than an hour for both 19H1 and 20H1 builds. 

If my statement above is correct then the next OS Build should solve the problem for me .. ???

I'm not being foolish in my thinking in this am I?

If I remember correctly the program informs you of the programs it will remove, so if you have the disks or the download links there is no problem. Waiting for the next update is quite reasonable, but as for the next build solving the problem...? How long is a piece of string?

In my limited experience, if your build has a lot of problems and you state that you have not clean installed ever, you could have a lot of embedded faults. But wait it out and see. There is no right or wrong with these Insider builds, just personal preferences.

I also have build 18850.1000 installed and (to this point) have not experienced this.  I will double check this evening when I get home.

I went through the contents of OneDrive and did not have any problems opening, editing or otherwise manipulating files with build 18850.1000.
