New Mobo, CPU, & GPU. Should I reinstall Windows?

I am currently running Windows 8.1 (64 bit) and I recently installed new hardware (Mobo, CPU & GPU). Should I reinstall Windows? After placing in my new hardware, my PC booted up just fine but I've noticed a couple of issues. For example, now of my programs will execute from the home screen any longer. I have to go into the program files folder and manually execute the app or either use the search bar to find the exe file.
I've also been trying for the life of me to get that windows logo to appear on my taskbar so that I can install the windows app in preparation for the windows 10 upgrade but whatever I try doesn't seem to work.
The fact that I chose not to reinstall windows could this be causing my problems? The only reason I didn't reinstall is because everything "seemed" fine at first.
Thoughts?

Have you updated/installed the drivers to the new hardware in device manager(if needed don't forget to show hidden devices) or the manufacturer sites?

Then try:
Dism.exe /online /Cleanup-Image /StartComponentCleanup&sfc/scannow&Dism /Online /Cleanup-Image /RestoreHealth&sfc/scannow&pause
in an admin command prompt.

Yes the drivers have been installed via the manufacturers' websites.

You might have to sysprep it.

Are these 3rd party programs or are these features within windows?

Will Refreshing the PC help at all?

Ok I'm in the process of running that now. I will post a screenshot once it is complete.

Ok here are the results...

Ran it again. This was the result.

It looks like system file checker (sfc /scannow) wouldn't complete for some reason. Try just running in admin cmd sfc /scannnow reboot then try again to see if it completes.

I've already reinstalled Windows 8. Working on installing 8.1 as we speak. Thanks for the recommendation though.

You're welcome. After the first set of commands(SFC & DISM) it should have looked like the below picture that contains false positives because of the windows update to do with telemetry for the Win10 upgrade.


Just for future reference, if you wish, here is a mini tut I have created, so I just have to copy & paste to help people.- It's good for Win8 & Win10:

You can try fixing the files by copy & pasting in an Admin
Command Prompt:

Dism.exe/online /Cleanup-Image /StartComponentCleanup&sfc/scannow&Dism/Online /Cleanup-Image /RestoreHealth&sfc/scannow&pause

And let it run through then
reboot and run it again to check if it cleaned everything. It
may take a while depending on your hardware(HDD or SSD), and it may
appear to freeze at 20% on the third part, just be patient and
let it run out.

:note:: Only 2 false positives will show up(this is the result of the GWX software as Windows has nothing from the original OS software to compare it to´) and they are(in red):

his update enables the Diagnostics Tracking Service in Windows 8.1,Windows Server 2012 R2, Windows 7 Service Pack 1 (SP1), and Windows Server 2008 R2 SP1. This tracking service collects data about functional issues in Windows.

This update contains the following two manifests that are occasionally updated by the Diagnostic Tracking Service

•

• utc.app.json​

The two files are marked as static files in the update. When an advanced user runs the System File Checker Tool (sfc.exe), the files are unintentionally flagged as corrupted. There is no impact or corruption on a device that is running this update, and this issue will be fixed in a later service update.　​
