Windows 10: Side by Side Configuration error and some of my programs will not open

I am getting a Side by Side Configuration error and some of my programs will not open. Any suggestions?

:)

 

is there any demand for a system configurator?

Processor(V) <--drop down arrow
-AMD(V)
--Socket(V)
---AM2(V)
----List of cpu's
---939(V)
----List of CPU's
-Intel(V)
--Socket(V)
---775(V)
----List of cpu's
---771(V)
----List of CPU's


etc etc.

 

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.

 

CD drive error

1) Close all open programs
2) Click on Start, Run, and type REGEDIT and press Enter
3) Click on the plus signs (+) next to the following folders

HKEY_LOCAL_MACHINE
SYSTEM
CurrentControlSet
Control
Class
{4D36E965-E325-11CE-BFC1-08002BE10318}
4) This folder is the DVD/CD-ROM Drive Class Description in the registry. Look for any of the following names in the right hand column.

UpperFilters
LowerFilters
UpperFilters.bak
LowerFilters.bak
5) If any of the above keys shown in step 4 are listed, right-click on them and choose Delete
6) After deleting the keys, close the Registry Editor
7) Reboot your computer
8) Open My Computer and check to see if your CD or DVD drives have returned. You may also want to open Device Manager and verify that the yellow exclamation and error code on the CD or DVD drive is gone.

And it likely has something to do with the emulated drive you have listed there.
