I hope this is intelligible! remember, humble home user (occassional stirrer ) Looking for some education and advice. I have been checkingout/considering uninstallers. The two which seem to have highest kudos are Ashampoo and TU from G.Martau. Not unhappy about paying reasonable amounts to save endless manual cleaning fiddles if they work. Both use "snapshots" to record installation and then complete the "snapshot" after reboot and first run of the software to pick up any windows "stuff" What I'm not sure of is snapshot of what? If I install and record several apps how will/how does the uninstaller separate each "snapshot". If I install several apps in a certain sequence wont they then have to be uninstalled in the same (reverse) sequence? (this feels like trying to explain time travel paradoxes and english is my first language!) Once again I demonstrate my lack of OS knowledge Those with knowledge of these things are probably shaking with laughter! I have toured through the TU forum and asked similar question there with limited understanding of replies. And, out of interest can any body comment on how well these uninstallers might work if faced with something like (shudder) recording and uninstalling Symantec AV, Firewall, etc ANy comments about these tools and how they work and might work with multiple out of sequence installs/uninstalls? Thanks. Regards.
