my programs still working after fresh install

Specs: Windows 7, 2.699 GHz / 759 MB
I split my HD into 2 partitions, and installed windows ONLY on c:\ and placed all my documents, and installed all my programs on the D drive. Well after a recent crash I formatted and fresh installed windows on C, leaving D intact. Expecting I would have to reinstall all of my software, I noticed that a lot of the programs installed on the D drive are still working. Obviously, there are no shortcuts to them in the start menu, or options to uninstall in the control panel, but should I just keep it like it is, and manually make shortcuts in the start menu and such, or should I reinstall anyway?

It is generally recommended to install the OS and applications on the same partition. This provides the best performance and the simplest configuration. And there is little point in doing otherwise as you really should be installing applications after installing the OS. Many applications won't work at all if you don't while others may exhibit unusual symptoms. Every application is different. Your applications are operating under conditions they were not designed for. Some will forgive you for this. Others will not.

There are no issues with documents
and other data on a separate partition.

I respectfully disagree with the above. I recommend installing all but a few core programs on a different partition.

I would just re-install the programs to reestablish the proper links.

In the future if you image both partitions then restoring either partition will put the computer back to the same state it was in when the two images were made. That is the main advantage of installing to separate partitions.

You will find that those partitions will need to be re-imaged at different intervals. I would recommend leaving the Documents folder in the default location and simply performing an interval image more often on the C partition.

The only time you will need to re-image the D partition is when you install a new program. Failure to image at that time would only force you to re-install any programs installed after the last image.

That is where the core programs I mentioned come in. Any program that requires constant updates like your AV or malware programs should be installed on the C partition. That is where all or most of the changes occur.

Finally, I recommend a third or more additional partition for things that aren't really tied to the OS. Movies, photos, music, etc. are all usually in a compact file that can't be compressed much more if imaged therefore imaging of that partition is not necessary. Simple backup of those files is an easier solution.

Setting up a drive in this manner requires the least amount of maintenance.

I backup the OS partition to DVDR and I usually use only three disks total. Optical media is the best type for backup/imaging, IMO. Once made it is easy and cheap to duplicate for even more security. I keep a lot of files in the Documents folder so I use a file comparison program to maintain a running copy of that folder on an external drive.

Beyond compare is the name of that program.

Yes I do install "core" programs within the same partition as the OS and do make images of the partitions for backup/recovery. This time I wanted to do a clean install of windows anyway because my backed images (of the windows partition) was full of years of garbage anyway, and just restoring to that point would resore it to a "slow" state. I was ready to start reinstalling all my programs when I noticed many, but not all, of then were still running whichi is when I started this thread. For now I think I will keep it like it is but reinstall anythig that is NOT working, then manualy create the links for the start menu, etc. Many of theose programs that are still working are just simple gadgets anyway and not needed for major function/productivity

Simple programs may not have any dlls and that is why they are still working. For the other programs your could try to run them by using Windows explorer the find the exe in the program folder and clicking it. Just might work. I had heard that Windows 7 was supposed to look for installed programs and configure them but I can't recall if I heard that from a reliable source or not.
