Windows 10: Some tabs are missing

It's been like this for a few months since developer beta, I've tried these steps but none of them works, is it because of the region setting? 1. wsreset.exe2. sfc /scannow3. clean install windows

:)

 

The readyboost tab is missing but is enabled in services.why?

Can you insert a different SD card on it to check if the same issue will happen? Which version of Windows are you using on the other device where ReadyBoost tab appeared? Is it running Windows 10 as well? This will help us isolate if the issue is only happening
with the SD card or the computer itself.

Meanwhile, we suggest performing the System File checker as it can help detect possible corrupted or missing system files that can be causing the issue. Kindly follow the steps below:

• Open Cortana/Search.
• Type in Command Prompt.
• On the Search results, right-click on the best match for it and choose
  Run as administrator.
• On the Command Prompt window, type in sfc /scannow then click
  Enter on your keyboard.
• Restart the computer after the process, then check if ReadyBoost tab will appear.

Update us with the outcome.

 

Location Tab Missing from Almost All Folders

I assume your referring to the Location tab in the Properties of user folders .... Documents, Desktop, Downloads, Pictures, etc

If the tab is missing, it would suggest you're not looking at/accessing the actual user system folder, but simply folders that have the same name(s).

Do the folder listing(s) in Windows/File Explorer have the user system icon, or are they just plain common everyday folder icons?

Try restoring the icons to their default location C:\Users\username\

Note : "Restoring" doesn't mean simply copy/move > paste. The registry has to be adjusted accordingly. This forum has steps to do just that ...
Restore Default Location of Personal Folders in Windows 10

Looking at this part, and having second thooughts ...

Yo don't "create" user system folders, you have to re-locate them from the original system location (as indicated above).

But if you're referring to everyday-usage user-created personal folders ..... they don't have a Location tab.

 

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.
