Prevent Software From Accidentally Uninstall

I think you already know if everytime you install a software then the setup software will put uninstall entry in Add/Remove Programs where located in Control Panel. And maybe for security reason, you want to hide it from Add/Remove Programs entry. For example if we're preventing our integrated software which has to installed in every computer in our office, so all employees don't permitted to uninstall it. As an EDP manager you can remove 2 "gates" that looked easily to prevent other users to uninstall that software accidentally.

First way, you can delete Uninstall shortcut in its group inside Start Menu, usually every installer will put uninstaller shortcut too in Start Menu programs group.
Second way, remove uninstall entry in Add/Remove Programs that located in Control Panel. To open it just click Start Menu, click Control Panel then double click Add/Remove Programs icon inside Control Panel. You can see uninstall entry for all your installed softwares and we'll remove our important software from there. And to remove it we'll using Registry Editor for registry editing because we'll play again registry.
Open Registry Editor, to open it click Start - Run menu, type regedit then hit Enter key. Inside Regedit Editor, move your cursor and pointing to HKEY_LOCAL_MACHINE | SOFTWARE | Microsoft | Windows | CurrentVersion | Uninstall path. In this key, your installed softwares informations put here. Every software represents by confusing alphanumeric such as {505AFDC0-5E72-4928-8368-5DEA385E3647} or your software name directly such as Mozilla Firefox. If your software represents by its name directly you will not get any problem but on other hand if it represents with confusing alphanumeric it will not an easy effort to find it.
So, you don't look the keys name but focus to look the DisplayName entry that can found in every key. Uninstall name string that got in Add/Remove Programs list is taken from DisplayName entry. For example if you want to hide Mozilla Firefox from Add/Remove Programs list, pointing your cursor to Mozilla Firefox key then rename DisplayName key to NoDisplayName key name.
Close your Registry Editor and your Mozilla Firefox has hidden in your Add/Remove Programs.
