Well exactly 10 days later I have decided to roll back to Windows 8.1, not because I didn't like
Windows 10, but not only as mentioned before re : getting a new laptop down the road, but W10 did not like my Intel HD Graphics card. Many of my favourite games would not play Full Screen despite numerous attempts to try and fix this, thanks to Jenny100 suggestion  
``Are you able to reduce your desktop resolution in Windows 10?
If you are, does it have an effect on the size of the game window?``

Which at first didn't help, but then after having a Duh moment, I realized by reducing the Screen size down one notch from it's maximum or recommended size, that I could now activate the Scaling feature on my card, after choosing « Scale Full Screen » this helped in a few of the games I tested and brought it to a Full screen, but there were still too many games which did not.

The deal breaker was when Darrall mentioned that he installed Culpa Innata and got a shaky screen and could not play it, well I tried to install it and with the same results and I even tried the fix suggested by Jarkeld and the site he supplied, which did work But, the screen size was only a 4 inch by 4 inch screen and there is Absolutely No Way I am going to play one of my All Time favourite game in that size of screen and now that I have Culpa Innata installed, of course I now have to replay it and of course it works perfectly in W 8.1.
And all the games I previously tested works great on my puny laptop with full screen and all in 8.1. One thing to note though, I have a lot of No CD or DVD fixes for a lot of my games which helps enormously even in W10 to make it work.
As for rolling back W10 to your previous Windows, as long as you do it before 30 days, it is a Piece of cake and it took only about 30 to 40 minutes to roll back and everything was pretty much the same, almost as if I didn't even install 10.
One other important note, before trying W10, I did a full backup (system image) of my computer, just in case….

Really good to know all this, Starcom...

I was against installing Windows 10, but my son persuaded me and I am glad. I have installed and now playing Halo Combat Evolved with the download from Bungie. I have also installed Murder on the Orient Express, Outcry, Alter Ego and Murder in the Abbey. This Windows 10 may not be so bad after all for many of my old games.

I'm so glad to hear that you are having such good luck, kazzmo! I like the operating system in general, but I sure wish there were several things they would fix... like blocking certain forms of DRM.

I've thought about installing the Win 10 upgrade but heard that it has some serious big brother issues. What have you found about that Drac?

Has anyone gotten Amerzone to install on Win 10?

I gave my Amerzone game to a friend in California. I'll ask her if she's tried to install on Windows 10.

The GOG version of Amerzone lists Windows 10 - for what that's worth. I know they have also said that sometimes Windows 10 has been problematic for some games and for some players. I don't know about Amerzone specifically.

I tried from a disk and it wouldn't work. I'll check that link, thanks Marian.

Any idea if its watered down, like it was for Mac?

When I tried the Mac version from GOG, it was the watered down Anuman version.

However the version for PC from GOG was the old version, just made to work from hard drive instead of using the CD.

Thanks Jenny.

I found GK 1-3 too.

I just edited the original post to show a work-around for running the original disks for Gabriel Knight 3. A member at Mystery Manor couldn't get GK3 from GOG to run on Windows 10, but member RCB posted a work-around.

I don't have 10 installed, but doesn't my installer work for GK3? The GOG version is based on my installer. I would appreciate any input about Win10 compatibility issues.

Collector, all I can tell you is what RCP posted for us at Mystery Manor and that it worked perfectly for Stella. I will put him in touch with you!

Collector, yes your installer worked to run GK3 with Win10 using the original CD disc set. For reasons beyond my knowledge GOG states for GK3:

Works on: Windows (XP, Vista, 7)

I don't know if this is just an oversight in not listing Win8 and 10 or that the game tended to be problematic for other reasons with those operating systems. Currently I don't have the GOG version in my possession so unfortunately I can't say for sure at this point.
RCB

Thanks for the info, RayB. It's appreciated.

Good to know. Thanks. I guess that if anyone is having issues it will be a compatibility issue with that particular user's PC.

Probably a number of things on GOG's site that they missed updating as newer versions of Windows have been released. Could be that that info gets updated as releases are updated for bug fixes. They might not want to change that info if they have not tested on the newer Windows.

Hi everyone. I was wondering if the older Nancy Drew games will work on Windows 10?

Thanks for the info!

Tracy

There is a thread on the Her Interactive website about this that includes Windows 10 users reporting that they have been able to get every single Nancy Drew game (including the first two, Secrets Can Kill and Stay Tuned for Danger) running. The earlier games apparently require the same tweaking instructions that folks used for Windows 7/8. So, although I don't have Windows 10 myself, it would appear that it is possible.

Here is the thread:

Windows 10 Compatibility

And another:

Windows 10 Compatibility with original Secrets Can Kill and Stay Tuned for Danger

Thanks so much, Marian!

Tracy

That's great news... thanks, Marian. I don't have any of the ND games, so I couldn't check them out.

I'm not sure if this has already been posted or not , however , Vampire The Masquerade : Redemption (the physical copy) will install on Windows 10 . Launches with no issues , however , the brightness can't be corrected via in-game options . The game is next to impossible to play , at least to me anyhow , in darker areas due to this . The GOG version also behaves in the same manner .

I see that issue being discussed here.

If you look at the last two posts in the thread, there might be some helpful information there.

That thread was one of several threads I have read on the issue I've experienced . None of those fixes worked .

Hi again everyone. I was just wondering if you guys know if the Witcher 2 will play in Windows 10? ( not sure if you need more specs, but if so I'll be glad to get them for ya)

Thanks!
Tracy
