File Explorer is slow when traversing files synced with OneDrive

Hi,

I was in contact with Microsoft for over a year, and they finally confirmed it's a bug. a fix is on the way. The following workaround has proven to be successful:

Message from support team:

The Windows team has identified a bug on their end that occurs when numerous user sessions accumulate over time leading to these performance delays.

While the OneDrive fix is rolling out, admins on the AVD / VDI machines can manually clean up the sync roots that have accumulated over time, by deleting the child keys under:

"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\SyncRootManager\". 

Note: We recommend that users are logged off of any active user sessions before this cleanup or that the host is rebooted after the cleanup to ensure that OneDrive correctly re-registers with Windows

I hope this will serve as a solution until the fix is released by the end of the year.

Best,
Franco
