Help with reading a stringvalue (data) in regedit and using this in a script

Hi,

I have made a powershell script, which does some add/delete things locally on a client with MS onedrive problems. Please see the script attached.
I succesfull tested the script on my own client and that fine, but now i found out that the local sync location path is different and uses different locations and pathnames on all company clients and therefore i need to add some code to my script which does the following:

1) Read the following stringdata regkey

Path: HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Common\Internet\LocalSyncClientDiskLocation
Type: REG_MULTI_SZ
Data: C:\Users\dfbdp\OneDrive - Danske Fragtmænd A-S

2) Insert this datavalue (path of folder) into the "Move-Item "C:\Users\$env:username\OneDrive - Danske Fragtmænd A-S""C:\Users\$env:username\Desktop\Onedrive_Backup"... in the script so the script reads the pathlocation from the regdatabase and then insert this into the path and moves these files into the "Onedrive_backup" folder etc.

I have tried to solve this problem my selv with the Get-RegistryKey etc but have not been able to make it work.

I am not that skilled in this, so can anyone help me?

Best regards
BDP
