Windows Share Across Users

  • If you have connected a network share for a certain user and want to access it, e.g. via an elevated powershell it might not be visable (e.g. caused by UAC)
# create/set DWORD to 1 and reboot
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\EnableLinkedConnections

Set Windows NTP Server

  • Per default Windows is calling Mircosoft NTP servers, to change this do the following
# set new ntp server
Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\w32time\Parameters" -Name "NtpServer" -Value "my.fancy.ntpserver"

# restart service
Restart-Service w32Time

# sync
w32tm /resync

# check
w32tm /query /status

Windows 11 Install Without Internet

  • Since M$ is forcing to use a Microsoft account for installation of 11, hence an active internet connection, this sucks for some people
  • Out of Office Experience for the help
# Step through installation procedure until network requirements
# Press 
SHIFT + F10

# In the the opened command prompt enter
oobe\bypassnro.cmd

# after automatic reboot, step through installation procedure again ...
# ... in the network requirements menu, you can now use the "I don't have internet" option
  • If Microsoft is removing the bypassnro.cmd script, but not disabling the registry keys
# Reg key
reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\OOBE /v BypassNRO /t REG_DWORD /d 1 /f

# Cmd
@echo off
reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\OOBE /v BypassNRO /t REG_DWORD /d 1 /f
shutdown /r /t 0

# Powershell
Write-Host "Set BypassNRO" -ForegroundColor Cyan
& reg load HKLM\SOFT $workdir\Windows\System32\Config\Software
& reg add HKLM\SOFT\Microsoft\Windows\CurrentVersion\OOBE /v BypassNRO /t REG_DWORD /d 1 /f
& reg unload HKLM\SOFT
  • Another option is the following
# Step through installation procedure until network requirements
# Press 
SHIFT + F10

# In the the opened command prompt enter
start ms-cxh:localonly

# Create your local account
