I had a disk crash and no longer have an "F" drive. I had a bunch of GOG games installed there (F:\GOG Games\*). When I go to (Windows 10) Add and Remove Programs, the games are listed, but uninstalling fails, because it cannot find files in F: drive. How do I remove the games in Windows (from the list of installed applications that can be removed)?

To do it manually can be a real pain since you need to crawl through a large list of uninstall hashes:

An alternative are apps like CCleaner. Just download the portable version & check for obsolte entries
under Tools -> Uninstall:

Awesome, thanks! I have CCleaner - used that and it made it much easier to find GOG games as well as delete the entries. It was also much faster to delete Steam games that used to be on that same drive.

I recommend using geekuninstaller:
https://geekuninstaller.com/
It’s free, can remove, force remove, and delete any application, including windows ones. There is a tab for installed apps, so you can remove such rubbish as edge and cortana.

yeah just use that geekuninst app

In fact, I would anti-recommend CCleaner. It has a history of being bundleware, and worse.

Take a look at some fine alternatives.

Set the filters for your OS and preferably Open Source.

just like Chrome browser from Google.

Which (among many other reasons) is why I don't use Chrome.

I second this. Geekuninistaller is a boss amongst 3rd party install managers.

In windows if it can't find the uninstaller it may still offer to remove the reference of the game/program, although it may not be able to remove saves or anything else it has on hand.

Good point. I tend to go through at least the following areas and manually delete everything I don’t recognise:
Install folders, I have c:/mygames
Documents
saved Games
%appdata%/local, roaming
You can also check program files/x86.

Unfortunately even with the best uninstall software programs install files everywhere, especially modern games which seem to need things in several different places.

I use Revo Uninstaller Free, the portable version. I've tried Geek Uninstaller some years ago, and it was terrible, removing regitry keys completely unrelated to the software being uninstalled. I was monitoring its activity with tools like Regshot and SysTracer. Luckily, I did all the testing in a virtual machine. Maybe it got better now (hopefully), but I won't retest it anytime soon.

You can always use programs like Primo

You can easilly see what is installed on your PC once you install sth, even when you run the game which folders are created, registry keys etc.

There is also Total uninstall by Martau, fantastic program though not freeware.

Anyway, I delete everything manually and way always able to delete everything. It was a lot harder before regshot existed, now it is piece of cake I would say.

Yep, i prefer to do all that myself. The only thing I do have is the geekunistall, and that’s mostly to get rid of the windows bloatware.

It really shouldn't. The only place 'more than one' should go, is separate saves directory (which it isn't standardized so it could be one of 8 places) or the dependencies/dll's, which shouldn't be installed by that program anyways.

Of course in the event it can't find a certain set of dll's, if you put it in the same working directory as the program it will find it there... It's just part of the PATH.
