Too many, sure, to many of the same/similar kind, also yes.
I just had a day on my PC, evidently I like to try new software, had 2 Paragon hard drive utilities, Easus Todo backup and Acronis TI installed, they all install filter drivers and can stomp on each other causing system instability as I found out the hard way.
My real problems started when I uninstalled Acronis, Acronis is well known for leaving filter drivers behind and running after uninstalling and reboot, so I manually cleaned them up in the registry as I have done before, well it 7B blue screened on restart this time, crap, system restore, figure out what went wrong.
Uninstalled both Paragon software's and Easeus Todo, restart between each removal, Acronis crap still hanging around, edited the registry again to remove Acronis entries, restart, no blue screen this time, a long process to clean up my over zealousness to install too many of similar software's.
That's my recent experience with too much of a good thing.
