windows 8.1 hangs on Please Wait screen (restoreoptin)

<Modifying post to help other find the answer quickly>

I found another workaround that allows for still using skydrive, and further confirms the relationship to skydrive setup.

(This is the method I used)

1. login to the affected account
2. Press Windows Key + L to lock the computer
3. Switch to a user account with administrator priveledges
4. open task manager & switch to the "Processes" tab (Press "More Details" if don't see a processes tab)
5. find restoreoptin.exe & end task that process
6. switch back to affected account (Start Page, click your account name/picture, click the account you want to switch to)
7. Open Charm menu (windows key + C), select "Settings", then Change PC Settings
8. Select Skydrive
9. Modify the File Storage, Camera Roll, and Sync Settings (not sure which one does the trick)
10. logout & log back in
11. you should no longer be prompted with the blank 'please wait' screen

Another workaround that should achieve the same, as posted by others:

1. login to the affected account
2. Press Windows Key + r
3. Type:

taskkill /f /im restoreoptin.exe 4. Open Charm menu (windows key + C), select "Settings", then Change PC Settings 5. Select Skydrive 6. Modify the File Storage, Camera Roll, and Sync Settings (not sure which one does the trick) 7. logout & log back in 8. you should no longer be prompted with the blank 'please wait' screen

and just for completeness, you could also try:

1. login to the affected account
2. Press: Windows Key + r

Type:

taskkill /f /im restoreoptin.exe 3. Press: Windows Key + x

Press: a

Press: <Alt + Y>

(run cmd as administrator) 4. Type:

cd c:\windows\system32

restoreOptIn.exe /Ramp

5. Complete the Wizard

I fixed it much more simply. I had to recently rebuild my dell xps 27 and started with 8.0. Setup everyone's account since I have a home network and domain setup. Then upgraded, I ran into the same issue as everyone here in the post. What I had to do to fix is is unassociated all the windows live/Hotmail/outlook accounts from the domain accounts and then re-apply them. This then asked me to verify that the account has permissions to skydrive, and asked for verification. Texted me, I put in the verification code and it was fixed on all accounts. Someone also mentioned making it a local account and then reassigning to your windows account. Seems to fix it as well.

Steps for Domain accounts:

1. Remove association from your windows account
2. Re-add your windows account
3. verify that the pc has permissions to back up your info to sky drive/turn off sync with sky drive.

Windows Account:

1. Make it a local account
2. Re-add your windows account
3. Verify that the pc has permissions to backup your info to sky drive/turn off sync with sky drive.

Appears to be a bug in the 8.1 upgrade where the pc and sky drive trust is broken, it didn't happen until I received a windows update, but I could see this happening if you download the patches during the upgrade process.
