Great Feature ePO 5.3 - Policy and Task Retention 

If you need for any reason to remove an extension, ePO 5.3 give you an option to save all policies, task, etc. so you won't need to manually create them after re-install the extension or check-in the product.

On ePO 5.3 go to Menu -> Server setting -> Policy and Task Retention 

You can choose if to save the tasks & policies or not.

For example if you choose to Keep policy and client task data, then you remove the extension of Virus Scan

Now go to Policy Catalog
The Virus Scan policies is exists, but you can't edit, rename or delete

If you try to enter to the policy you will receive an error

When you re-install the extension you will have the same policy with normal actions

McAfee Drive Encryption 7.1.3 (DE)

Problem:

When trying to boot from recovery boot disk of McAfee Drive Encryption there is a message 
Operation system is missing.

Solution:

1.  Get a USB Drive of sufficient size to contain the OS installation files you desire to install. (this drive would need to be at least 1 GB in size)
2.  Make sure the drive is completely empty of its contents.  (There should be absolutely nothing on it, if there is and you want to keep this stuff you need to move it elsewhere now.)
3.  Plug your USB drive into a USB slot on your computer. 
4. Make certain the drive is recognized, make a note of the drive letter.  Mine happens to be F:\
5.  Go to the start menu and USING ADMINISTRATOR CREDENTIALS open a command prompt.  I right clicked on command prompt and chose to Run As Administrator.
6.  Once your command prompt is open you are going to run a series of commands using the DiskPart utility.
