You can run sfc more than one time to catch / fix more errors -- and you may end up having to look at the .log file to see what you need to fix manually. .LOG files are text, open with Notepad.
I have pinged ShlomiL - if he is around and available, he may get back to us. We are all volunteers and we are spread around the globe -- folks come and go as they wish / need. Smiling.
I don't like errors that include not being able to use WebScan -- that program is not printer software driver dependent. It makes the issue worse in that the Windows vanilla print drivers on the system are apparently failing.
You may end up having to run a Recovery on the OS. Eww.

A great leap here, based on very sketchy data:
Printer software and other installed programs require at least a certain level of .NET Framework to be installed and functional (uncorrupted and enabled).
I believe you must have at installed, at absolute minimum, .NET Framework 3.5 -- the actual version required for some programs to run on your computer may be higher.
.NET Framework 3.51 should be included in your OS; check / enable it in Windows Features.
How To Install Microsoft .NET Framework 3.5.1 on Windows 7
Some program sets on your computer may like to have .NET Framework 4.x installed (and enabled).
Microsoft .NET Framework 4 (Web Installer)
Once .NET Framework 4.0 installed, you can perhaps update that package to 4.5.2:
Microsoft .NET Framework 4.5.2 (Web Installer) for Windows Vista SP2, Windows 7 SP1, etc.
I continue to be concerned that you cannot run Webscan -- the program is not dependent on your printer software (Full Feature Software package).
Windows Updates are not as common for Windows 7 -- there is perhaps an Update that has compromised your File System.
You could try using System Restore to take the system "back in time" to a date when the system was working as expected. (Have the complete system backed up before running System Restore.)

Windows Process Activation Service is part of your Services:
Control Panel > icon view > Administrative Tools > Services

4. An interesting note - I look at my laptop's and my desktop's Program Features list side by side and they are identical except for one item that I cannot enable on the desktop - the Windows Process Activation Service where there is a checkbox for .NET Environment. On my laptop, it is checked, but not on my desktop and I cannot enable it. I get a failure message when I hit "OK."
Does that give you any hints?
Not sure -- both my Windows 10 systems are set to run the WPA Service Manually (trigged by program start) -- perhaps the service must be running to change the configuration in Windows Features.
Or maybe the manual start is not working as expected when called. Note the dependencies are the same as those requested by WIA.
Open Services, scroll down > Highlight Windows Process Activation Service > Start
Good to hear that Webscan works -- irregardless of the fact it is a pain..
Try using one of the alternatives here:
naps2 and Infranview are nice scanning programs.
Yes, recovery is a large inconvenience -- and it may end up not helping. It is a personal decision at what point you decide to try it.
If you can do so, I would suspect if there are File System issues, these are located in the main install disk (where Windows is located / installed) -- Restore the main disk / OS.
If I think of anything else useful, I will post back.
