Windows 10: Strange Windows 10 behavior

I just assembled my first gaming PC with AMD Ryzen 7 5800X, Radeon RX6900xt, 16GB RAM and Samsung 1TB SSD. I am experiencing a strange behavior. After playing for about 2 hours, the background windows that were open while I was playing the game started malfunction. The top tab disappeared, the close button x b

Registry strange behavior in HKEY_CURRENT_USER\Software\Microsoft\...

I tried to clear all contents of
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts
then set security permission to logger user name () to be clear from:

• create key
• set value

and let it inherently apply to all keys under it

But it responds with icons flickering / blinking very often
so I undo the security setting.. but while keeping on registry browsing under this key I came across:

1. The jpg filetype key and userchoice key were created
2. On userchoice key the logging user () ACL was created, and
3. It's set to DENY on SET VALUE !

Is it windows 10 behavior or an intruder's been screwing up ?
Please help me.. many thanks in advance

 

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

Strange behavior of the Start menu

You can add shortcuts in the start menu, alphabetical list, by adding them in the old start menu location. What is strange is that if you add several shortcuts to the same program with different parameters, only one appears on the list, why ? No idea. Anyway
it appears with the right icon, the one defined by the shortcut. If this entry list is pinned to the start screen, it appears with the icon of the exe file, not the one of the shortcut. Second strange behavior. I regret all this. The start menu of W10 lost
something very important in the W7 and previous versions. The ability to create a hierarchical menu : one for internet, one for multimedia, one for office programs etc… The actual start menu is a real mess compared to what could be done in W7. This can be
partly solved by the start screen : it’s possible to create folders, one for internet, one for multimedia ad so on, and the folders can contain pinned tiles to the right programs. Anyway, its’ completely impossible to create several shortcuts to the same program.
For example one for starting the browser to one a website, one for starting it to another website and so on. Personally, I solve this by using an alternate shell able to manage several shortcuts to the same program… and to choose the icon. Anyway, this behavior
of the start menu remains very strange, and makes the start menu of W10 less usable than the ones of the previous versions of windows (not W8 of course which was a complete failure).
