Undoing a change You can undo each change, one at a time, if the changes have not yet been applied permanently. A restart of the thin client is required after each undo. To undo a change made with the Component Manager: 1. In the Component Manager, select Revert Last Change. 2. Select Yes to restart the thin client. Repeat this process for as many changes you want to undo. IMPORTANT: If you take a snapshot of the image while testing a new configuration, you cannot undo the changes via the Component Manager. Those changes can be undone only by restoring a previous snapshot via the Snapshots tool. However, this does not work if the changes have already been applied permanently, because that function deletes all existing snapshots. If changes have already been applied permanently, you must reinstall the operating system to restore most removed components. Some components (such as Citrix, RDP, and VMware Horizon View) might be available as add-ons on the web and can be restored by reinstalling them. Applying the changes permanently To apply changes made with the Component Manager permanently: IMPORTANT: After the new configuration is applied permanently, all snapshots are removed and a new factory snapshot is created. Removed components cannot be restored after this point. 1. In the Component Manager, select Apply Component Configuration. 2. Select Yes.
