Windows General

NOTE: For ease of life when opening either the command prompt, Powershell or Regedit run them as an administrator.

HOWTO: FIX:

Reset Network Adapters via commandline

Open either the command prompt or powershell as administrator, then run the following commands:

netsh winsock reset
netsh int ip reset
netsh int ipv6 reset
netsh advfirewall reset
ipconfig /flushdns
ipconfig /release
ipconfig /renew

Ignore messages about problems with Bluetooth adapters, then reboot the system.

For testing:

ipconfig /release
ipconfig /renew
arp -d *
nbtstat -R
nbtstat -RR
ipconfig /flushdns
ipconfig /registerdns

Exception Breakpoint Has Been Reached

This is an error that is often experienced when shutting down a system. In the case that brought it to our attention was a problem with OneDrive.

Windows Running Slowly

As with most things tech, this fix is not the be all and end all to fix a slow running system, but it is a place to start.

Open a command prompt:

sfc /scannow
Dism /Online /Cleanup-Image /ScanHealth
Dism /Online /Cleanup-Image /CheckHealth

If DISM reports a fault run the following:

Dism /Online /Cleanup-Image /RestoreHealth

To check for any errors, the log file is located at:

C:\Windows\Logs\CBS\CBS.log

When SFC has completed, run the following:

findstr /c:"[SR]" %windir%\logs\cbs\cbs.log >sfcdetails.txt

The text file is outputted to the root of the user's directory.

For further information on deciphering the output, see the Microsoft Knowledge Base article found here.

Error: "Windows Update Cannot Check For Updates"

Batch File to Release TCP/IP, Flush DNS, Reset Winsock, Reset Proxy

Copy and paste the following in to Notepad and save as a batch file:

ipconfig /release

ipconfig /flushdns
ipconfig /registerdns

Once you have the batch file run it in a command prompt.

Thanks to The Windows Club.

Windows Apps (Windows 10 & 11)

Open the PowerShell, then run the following:

Method One

Get-Appxpackage –Allusers
Get-AppXPackage -allusers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

Method Two

Get-AppxPackage -allusers | foreach {Add-AppxPackage -register "$($_.InstallLocation)\appxmanifest.xml" -DisableDevelopmentMode}

After running the above a system reboot is required.

Generate File Listing On Shell Menu

Note: The following creates when you right click on a folder an entry in the shell menu called 'Create File Listing'. This creates a text document listing of all the files with in a folder, with the resulting text file saved in the folder itself. The listing is a plain list of all the files, if you want to have listed in the document details of the files themselves i.e. dates, then drop the /b switch.

Open Notepad and paste in the following text:

dir /a /b /-p /o:gen >filelisting.txt

Save the file in to the Windows directory calling it file_listing with a .bat file extension not .txt

Open Windows Explorer, click 'Tools' --> 'Folder Options' click on the 'Files Type' tab, find and highlight 'Folder' then click the 'Advanced' button.

Click the 'New' button, in the 'Action' box paste the following:

Create File Listing

Then browse to and highlight the .bat file created above.

Click all the 'OK' buttons as required.

DNS cache - Clearing/Flushing (Windows 7/8/10/11)

Even with a web browser's private mode enabled Windows still (inadvertently as this system was in place long before private mode browsing) tracks the websites visited by the machine via the DNS cache.

Output the contents of the DNS cache to a text file (the complete cache may well be too large to display in the terminal):

ipconfig /displaydns > dns.txt

Sample output:

Windows IP Configuration

   mozilla.org
   ----------------------------------------
   Record Name . . . . . : mozilla.org
   Record Type . . . . . : 1
   Time To Live  . . . . : 2
   Data Length . . . . . : 4

   A (Host) Record . . . : 63.245.215.20

   mozilla.org
   ----------------------------------------
   No records of type AAAA

To clear the DNS cache:

ipconfig /flushdns

System File Checker (SFC) Syntax

/scannow Scans all protected system files immediately
/verifyonly Scans all protected system files immediately, but without repairing
/scanonce Scans all protected system files once
/scanboot Scans all protected system files every time the computer is restarted
/revert Returns the scan to its default operation
/purgecache Purges the Windows File Protection file cache and scans all protected system files immediately.
/cachesize=x Sets the size, in MB, of the Windows File Protection file cache
/? Displays help at the command prompt

If SFC detects a corrupted file it will pull a copy from C:\Windows\WinSxS\Backup\, or if the directory is unavailable or itself corrupted the file will be drawn down from the internet.

Winget

winget list

NOTE: This will display all the packages that Winget can manage along with their ID reference.

winget upgrade --all

winget export -o X:\list.json # Where 'X' is the drive letter of the drive being saved to.

winget import -i X:\list.json # Where 'X' is the drive letter of the drive being imported from.

OPTIONS: --accept-package-agreements --accept-source-agreements

NOTE: The .json file is saved in plain text so can be edited to suit the system needs.

winget search <query> # EG: obs

winget uninstall <query> # EG: 69420

NOTE: Uninstallation is done using the packages ID reference not its name.

NOTE: While the option to uninstall via Winget is available it is safer to use Windows Add/Remove Programs GUI as using the command line may result in dependencies for other installed packages being removed!

Background Intelligent Transfer Service (BITS) - Limiting Bandwidth

After much tarting around we found that the simplest solution to this issue is to purchase a modem/router that can instigate limiting the bandwidth on a system-by-system basis. Windows 11 does provide the ability to limit the speed of Updates, which can cause local area network slowdown.

OEM Information

Open Regedit
Navigate the the following key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\OEMInformation

OEM systems, say those from manufacturers such as HP will display the following entries:

Logo
Manufacturer
Model
SupportHours
SupportPhone
SupportURL

Systems that created from a clean install will not display any values, and will need to be added.
To do so highlight the OEM key, then right click, select New > String Value and add one of the entries above.
Rinse and repeat for those you wish to add
Next double click on the value and in the resulting window add details in the Value data: box
Click OK
Rinse and repeat as required

NOTE: The OEM logo should be in .bmp format and no larger the 150x150 pixels, the file path will be needed in the value data.

Once all the information is entered correctly the entire key could be exported for use on other systems.
