This drives me nuts! Uninstall programs leaving their naughty bits on my computer.
This is an email checking app I have on my desktop and two laptops. I buy a new laptop and now we have windows 10 everywhere. The wife complains her laptop keeps disconnecting so I trade my laptop (the new) for hers. Email checker won't recognize her account even though it recognizes 3 others that we have. Furthermore, the other two computers will recognize all 4 accounts.
My initial reaction is that this can't happen. Same program on 3 windows 10 computers, but only 1 is acting up? OK, only possibility is faulty installation on the new
computer. So I uninstall the email checking program. Download and reinstall a new download. I go into the program prepared to setup all 4 accounts, but they are already there! And my dear wife's account still cannot be accessed!
Thanks to the developer, there was a text file that indicated that the account details were recorded in the registry and gave instructions to locate them. Once I deleted those keys I was able to set up my wife's account which now works.
In an ideal world, when you uninstall a program, it should remove every trace of itself. anything else in my mind is malware or perhaps nuisanceware.
Is there anything out there that can examine your system and remove the naughty bits?
Comments would be welcome, I thirst for knowledge.
