What is TrustedInstaller? And why does it have more rights than me?

[dc2000]

I have always used Windows XP and did not buy into Vista until recently when I got a new laptop that came with it and later was upgraded to Windows 7. The laptop also came with a small partition called RECOVERY that was designed to restore Vista. Since I deleted it and installed Windows 7 I did not need that recovery partition anymore and decided to erase it and use it as a scratch disc for the Adobe products.

I knew about the admin access and UFC (or whatever it's called there) and I logged in as administrator and started deleting folders on that recovery partition (disc D:). It removed pretty much all the files and then, to my surprise, displayed a message that I do not have access to a group of certain files and that I need to have a permission from a TrustedInstaller, or something in that nature to delete it.

I did some quick Google search (painfully remembering people's woes with Vista) and found the way to change access rights for Windows users, but for some reason I could not neither find, nor add that TrustedInstaller, and my admin user account had all privileges checked except a grayed one that reads "Special privileges".

So, I'm totally confused. What is that TrustedInstaller and how come "it" has more permissions than me???

If you wish to keep partition "D" for Adobe Products, just format it using Disk Management from within Windows 7.

Open Computer Management by clicking the Start button , clicking Control Panel, clicking System and Maintenance, clicking Administrative Tools, and then double-clicking Computer Management. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

In the Navigation pane, under Storage, click Disk Management.

Right-click the volume (In your case "D") that you want to format, and then click Format.

To format the volume with the default settings, in the Format dialog box, click OK, and then click OK again.

Dont forget to make yourself a Windows 7 Repair Disk.

Windows 7 also incorporates a very interesting feature: the creation of a repair disk directly from the system.

In Control Panel, click System and Security (System and Security), and then click Backup and Restore.

In the left pane, click Create a system recovery disk (Create a system recovery disc);

Insert a blank CD in the DVD, and then click Create Disk.
