STORAGE-windows 11-update

The available space on C: drive reduces after a windows update; the temporary files are "windows update clean-up" 4.54 GB.

I had 21GB, now only 13.8GB spare, 2.51GB temp was downloads.

I have not cleaned it up, the temp files may be needed, in the older windows 10, I think the update temp files used to deleted after 10 days.

I had to check why I had suddenly lost space, I had switched on storage sense, not sure what it does but have now switched it off as it seemed to reduce my spare storage space rather than free up space.

2022-09 Cumulative Update Preview for .NET Framework 3.5, 4.8 and 4.8.1 for Windows 11 for x64 (KB5017859)

Since this update my laptop keeps crashing/freezing and I have to force a shutdown with the power button and restart.

Windows updates seem to cause problems.

Widows 11 has also removed the windows update cleanup and my C: drive has returned back to normal with 21.9gb free.

I have not yet installed update 22H2, will wait for feedback first.

Windows 22H2 Problems

I posted this here as it refers to W11, however, the same things mentioned also happen on W10.🙄

WINDOWS 11 UPDATE- 29/11/2022

Security Intelligence Update for Microsoft Defender Antivirus - KB2267602 (Version 1.379.1116.0)

I watched the 22h2 YouTube video thanks, 22h2 feature update is still in development, but some issues now fixed by microsoft, not so good for business users or remote desktop.

I have not had any issues as a home user.

I found my system is more stable with updates if only one active antivirus is used, I have defender switched off but set to do scans and put defender exceptions in my own antivirus.

Also, windows 11 can become corrupt and I now avoid cleaning the registry which may cause problems and require re-installing windows 11, I have also done that when updates failed and use an admin account in Microsoft but also have a local account as well.

My windows 10 also works with 22h2 but has also been recently re-installed.

I always make and keep a recent windows recovery usb drive handy, and ensure the computer has enough storage usually 20gb needed

Each computer may behave differently, but I had more issues with 21h2 than I do with 22h2, so happy that my updates are working now.

PORT 5357 ON COMPUTER-windows 11

Both my laptops had this port open, it is for sharing on the local network.

I switched of sharing in network discovery, and this closed the port.

Not sure if the port 5357 should be open, or if closing it will cause any problems or it could be used by trojans.

It was only used on Windows 7 or Vista for network discovery, later versions of windows don't use port 5357, so should be closed, unless you have network discovery enabled (which allows sharing on the network, remote desktop etc) which you should then disable. It is disabled by Windows firewall, I think, as it's not open on my Windows 10. I think it can be used as a vulnerability.

https://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers 

Thanks, the list of ports is interesting.

Not sure why port 5357 was open and could be a vulnerability.

I have also blocked the port in the windows 11 firewall now.

Network discovery is now set to be switched off and is not enabled in the firewall.

I spotted the open ports doing a router check using an app on my tablet, which showed both laptops with port 5357 open, which was unusual.

A new RouterCheck does not show the port 5357 open now on my windows 11 laptop.

An online scan shows all common ports on my router are closed, but  a RouterCheck shows there are open ports within the local network which I presume are for communication between devices.

(local wi-fi network)

V6 TV box open port 443 

my own router-open ports 22,53.80,443 

Now TV box -no open ports

Epson printer- has 7 open ports

HP printer -has 5 open ports

Samsung tablet- no open ports

My own  router has no vulnerabilities in the database and passed 8 common vulnerability tests for home routers.

Acer Incorporated - HIDClass - 1.0.0.10 (6/03/2023) update for my own laptop.

These updates required required 2 restarts.

The update seemed to cause an unusual event, not noticed before, when I first switched on my laptop there was a timer circle,then the  laptop  was already logged in with an accounts page showing, I switched it back off and then it said too many attempts to log in so I had to type in a  displayed code to proceed and then logged in using my pin. At first I though it was suspicious activity but probably just part of the update system.

this may be due to a setting -

sign in options-use my sign-in to automatically  finish setting up after an update- (now switched off)

I also notice port 5357 was open so switched off network discovery in manage sharing.
