Windows 10: Windows file explorer window in my PC doesn't show and pop up anymore

The Windows file explorer window in my PC doesn't show and pop up anymore in my Windows 10 computer. It does highlight on the Windows taskbar where I can see that that window is opened and also, I can hover over it with my mouse cursor and then its little explorer window icon pops up on the task bar but that's it, the big window itself doesn't show up or is accessible anywhere.
I have all latest updates of Windows 10 installed. What I tried already: I uninstalled a couple of apps which I think I had installed around the time this problem started happening. And I also updated all my drivers with my paid/premium driver update software. But all with no success.
I never had this kind of problem before and I don't know what else to do.
I could uninstall all remaining apps on my PC one by one and see if that fixes it but those are still quite a lot of apps and then I would need to re-install them later again. Not sure if I should do that.

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

Windows Explorer Replacement?

I don't use Internet Explorer, I meant the thing where you can look at files etc. Hotkey Windows+E. Maybe it's the wrong name in english though. *Stick Out Tongue

 

Some files listed in Windows Explorer are blue font

I seem to have run out of room on a Windows XP Pro system. I tried to defrag but don't have but 7% room available. I looked in Windows Explorer to try to find some huge files that might be corrupt and I see a few that are listed in blue. What does that mean? I have not compressed anything on purpose. Thanks
