When removing the virtualization/streaming agent the uninstall leaves behind some registry keys and some virtualization cache behind. If there is a need to completely remove everything you can follow https://support.symantec.com/en_US/article.HOWTO50209.html. I have automated the workaround with a few options.
wmic product where name="Symantec Workspace Virtualization Agent" call uninstall /noreboot del /f /q c:\fslrdr reg delete "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\FSLX\Parameters" /f shutdown /r /t 0
NOTE: change the wmic product name to whatever you are wanting to uninstall
$wmiccommand = 'wmic product where name="Symantec Workspace Virtualization Agent" call uninstall /noreboot' RunWait('"' & @ComSpec & '" /c '&$wmiccommand, '', @SW_HIDE) RegDelete("HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\FSLX", "Parameters") DirRemove("c:\fslrdr" [, recurse = 1] ) Shutdown (6)
NOTE: after building and compiling the script you can use the autoit tools to convert to a .exe so that you can remotely run the uninstall without any user interaction.
Good article, this is nice if you wan't to move over too another tech like Appv. Ps3.0 or above can't be intalled on our Windows 7.x64 machines without removing sws and swv first. Or if you wan't to run them side by side they must be uninstalled first anyway before you can reinstall them.
