Windows 10: Yellow exclamation icon on C:Disk and an additional 'Account Unknown' in the security tab.

I recently saved an excel file and while using file manager I noticed a yellow exclamation icon next to C disk. I checked online and saw mention of file space being one of the reasons but there is 299GB free space. While checking the security tab I noticed 'Account-Unkown' with several numbers following it. I have never created another account on this device. - I ran Mcafee quick-scan in the middle of full scan and no threats were found. - Windows security doesn't indicate any issues. - Error checking on C disk returned no issues. *Windows 11 Home, Version: 23H2*OS Build: 22631.3737Windows E

Yellow exclamation mark on wifi

Sir there is no yellow exclamation mark on wifi in device manager. There is yellow exclamation mark on wifi icon on the taskbar.

 

showing a yellow exclamation mark on local disk C

I have recently reset my pc, because it needs a bitlocker recovery key every time when I open my pc (with window 10)

resetting was done. this time no recovery key is needed to open the PC, but after that I saw some yellow mark on local disk C with an open lock

local disk C is showing a yellow exclamation mark. Its space is already empty.

I read the article about that explaining some bitlocker on and off.

but the disc is not showing such an option as "managing Bitlocker" or "Turning bitlocker On And Off"

 

Yellow Exclamation mark over Internet icon

Hello, I have Windows 10 pro and I am able to connect to my Router wifi without any issues and have a working internet connection. I am able to browse internet and ping my DNS server, gateway etc, no issues but there is an yellow exclamation mark over the
wifi internet icon in notification area. When I take my cursor there, popup says Limited connection next to my SSID!! When I click on it, below wifi icon, tag says "no internet". Earlier this yellow mark used to appear when there was no internet access. What
all troubleshooting I have done:

• Updated the wifi card drivers.
• Checked for any firewall/security software conflicts.
• Upgraded the router firmware and also used another router.
• Changed the DNS from ISP to google to other open dns ip addresses.
• Deleted and recreated wifi profile.

Please suggest what else I can do and if I am missing something. Thanx
