I have hundreds of Windows 7 machines that I want to uninstall Adobe Flash Player silently, without the user intervention. I read several forums, saying use the -silent switch with uninstallflashplayer.exe in a command prompt, but it doesn't work.
Default viewer¶
Note
Windows 10 environments require using DISM and GPO configuration.
When Reader and Acrobat are installed on the same machine, you can choose which viewer is the default for PDF files. In some cases, this choice is critical as Reader has a built in Protected Mode which is more secure. For security details, see the Application Security Guide.
To select a default viewer, choose one of the following:
Adobe Silent Install Command Line Code
- Installer will decide which product will be the default: The installer decides which application should open PDFs based on the product to install and the values of IW_DEFAULT_VERB and LEAVE_PDFOWNERSHIP. In general, the install leans towards letting the more secure Reader be the default viewer unless a property or user choice overrides that decision.
- Make Reader the default PDF viewer: For Reader MSI modification only. Sets IW_DEFAULT_VERB to Read.
- Make Acrobat the default PDF viewer: For Acrobat MSI modification only. Sets IW_DEFAULT_VERB to Open.
Note
IW_DEFAULT_VERB is written to the MST file and doesn’t exist in the installer tables by default. It can also be used on the command line or in the Setup.ini file.

Choosing a default PDF viewer
Property interactions¶
IW_DEFAULT_VERB interacts with the Adobe property LEAVE_PDFOWNERSHIP. NO
allows the new install to own opening PDFs. LEAVE_PDFOWNERSHIP is often used for silent installs where the usershould not be asked to select a default PDF viewer.
- YES prevents the new installation from taking over PDF ownership if PDF is already owned. However, if the PDF mimetype is currently un-owned, take ownership.
- If this property is unset or not present, the current install assumes ownership.

Locking PDF ownership¶

By default, users can select the default handler through the UI. However,administrators can lock the feature by setting[HKLMSOFTWAREPoliciesAdobe<product><version>FeatureLockDownbDisablePDFHandlerSwitching
to 1 so that end users cannot change the default handler.
