Windows 10: Relink Programs and Apps from another drive after a full Windows Reset

After having quite a few productivity problems with the latest Windows 10 ver 1909 that my laptop got. I decided to test if the root of my problems is the latest Windows update by rolling back to an older build of Windows 10 following the response to the very similar problem and situation presented in this question https://answers.microsoft.com/en-us/windows/forum/all/rollback-a-windows-update-without-any-backup/c8e300a5-e0c4-48aa-a33a-e554650654fe.


That said. up till now I took my time to uninstall all my programs before doing such a reset just in case. Alas for a while now I have always had the "logistics" to install many of my programs in another partition of my drive E. So I come to the question:

Is there any process that can use to effectively relink the programs into my OS in my C drive after the reset? Or is my only option to uninstall and reinstall always?
Years ago that I remember coming across a thread stating that I would need to do something with windows' Registry, but I am not sure if it applies anymore.

:)

 

Why did the startup window get cleared?

I didn't missed any step, the list was gone and gone , even after using lot of programs the programs were not listed in that list.

 

Programs Not Responding repeatedly even after resetting Windows 10

My 3-year old Windows 10 Home laptop is repeatedly unresponsive. The open programs will display "Not responding" for 1-2 minutes, then works for a few seconds before the cycle repeats. I've done everything I can think of to try to fix this (full list of what I've done is below) all to no avail.I notice that when this unresponsive state occurs, the "Disk" process in my Task Manager rises to 50%, even though there are just a few processes that are using 0.1 MB/s.I suspect it could be a driver conflict, but I have gone to my Device Manager and don't see any issues flagged. Could anyone suggest what diagnostic steps or diagnostic tools I could use to identify the source of this problem?------------Here is what I have tried:- Shut down my antivirus (Kaspersky)- Shut down Dropbox and OneDrive- Closed my Chrome browser, MS Office programs and all my other programs- Disabled Windows Search- Disabled SuperFetch- Restarted the PC (this takes some 20 minutes when I hit this problem)- Run Chkdsk and repaired drive errors- Reset Windows 10 (fresh install)It worked ok for about a week after I reset Windows 10, but the problem has since returned.

 

Default programs repeatedly reset to "MS" programs/apps

I had the same problem.
Possible causes:

1. Acrobat preference does not work and if you click on it, it will reset to Windows default acrobat reader with the message:
   
   
   
2. If Windows has update for Acrobat reader App, it will reset it to default.

Just set it from Control Panel->Default Programs->Set Your default programs
High lite Acrobat then click on: Set this program as default.
