Change default directory for Windows command prompt and Powershell when running with admin privileges

 Hi all,

It's been a while since I posted things.

Here is my previous post where the non-admin user changes the default directory for the command prompt and PowerShell.

https://psrdotcom.blogspot.com/2022/03/change-default-directory-of-windows.html

But in this post, I will be explaining about running the command prompt / powershell with admin rights and setting the default directory. Because, when you are running with admin privileges, it by default goes to the SYSTEM32 folder of Windows.

Environment

I use the command prompt and PowerShell, which are pinned to the taskbar of Windows.

Run the application with the admin rights

• Right-click on the application icon -> click on Properties
• Go to the "Compatibility" tab
• Check "Run this program as administrator"

Run the shortcut with the admin rights

• Right-click on the shortcut icon -> click on Properties
• Go to the "Shortcut" tab
• Click on the "Advanced" button
• Check "Run this program as administrator"

Change the command prompt default directory

• We need to have a .bat file with the following content
• @echo off
• cd <default_directory>

Now use the .bat file in the shortcut properties

• Right-click on the shortcut icon -> click on Properties
• Go to the "Shortcut" tab
• In the "Target" field append the below text
• /k "batfile_dirpath\batfile.bat"

Change the PowerShell default directory

• Right-click on the shortcut icon -> click on Properties
• Go to the "Shortcut" tab
• In the "Target" field append the below context after powershell.exe

• -NoExit -command "& {Set-Location <default_directory>}"

• Click on "OK"

Hope, this helps you to reduce the frequent directory changes in the command prompt and PowerShell.

Generate Free SSL HTTPS Certificates with 90 days validity using letsencrypt

 Hi all,

As discussed in my earlier blog, Generate Free SSL Certificate using ZeroSSL where the limitation of one free certificate on ZeroSSL can be eliminated using Get HTTPS for free!

This process includes the following prerequisites and procedures.

Note: This process is not for beginners or production usage scenarios. Use this process if you are knowledgeable about certificate generation.

Prerequisites

• OpenSSL command line
• [Li]nix / Mac OS

Procedure

• Open the URL https://gethttpsforfree.com
• It has 5 steps
• Account Info
• Certificate Signing Request
• Sign API Requests
• Verify Ownership
• Install Certificate
• In each step, some commands or processes need to be followed to get the free SSL certificate.

1. Account Info
1. In this step, we will be providing the email and public key.
2. Keep the generated private key security in your system.

• Note: If you are unsure about the public key generation commands, click on the "how do I generate this?" link, which is available over the public key input textbox.

2. Certificate Signing Request (CSR)
1. Generate the CSR for the required domains

• Note: You can generate the CSR for wildcard certificates and www subdomain with the same command

2. Try to follow the same format, including the line feeds mentioned below.

#change "/etc/ssl/openssl.cnf" as needed:
    #  Debian: /etc/ssl/openssl.cnf
    #  RHEL and CentOS: /etc/pki/tls/openssl.cnf
    #  Mac OSX: /System/Library/OpenSSL/openssl.cnf

    openssl req -new -sha256 -key domain.key -subj "/" \
      -reqexts SAN -config <(cat /etc/ssl/openssl.cnf \
      <(printf "\n[SAN]\nsubjectAltName=DNS:foo.com,DNS:www.foo.com")) 

3.  Sign API Requests
1. Sign all the requests with the private key

• Note: You need to copy the command and execute it on your PC/Mac terminal, and the result needs to be pasted on the web page.

4. Verify Ownership
1. In this step, you need to prove your domain ownership
2. You will be given 3 options
1. Python server
2. file-based
3. DNS record (I've used this option)
1. Update the DNS records with new TXT entries, and use the online dig tool to make sure the records are visible.
2. After we verify the availability of the records, you need to click on the respective buttons on the web page.
3. Repeat the same steps for each domain on CSR (www and any sub-domains).
5. Install Certificate
1. You will be able to receive your certificate in "chained.pem" format
2. Copy and paste the first certificate section (e.g. the first "-----BEGIN CERTIFICATE-----" section) into a text file named "domain.crt".
3. Copy and paste the second certificate section (e.g. the second "-----BEGIN CERTIFICATE-----" section) into a text file named "intermediate.pem".

• Note: Expand the "how do I install this?" link for quick help.

Hope this will help you to generate free SSL for your websites.

Change default directory of Windows command prompt and Windows PowerShell

 Hi all,

Today I will explain the steps to change the default directory for Windows command prompt and Windows PowerShell.

The default directory for both the command prompt and PowerShell is the "system32" folder of the OS installed directory (By default: "C:\windows\system32").

Day in - Day out, we will open the terminals (command prompt / PowerShell) and navigate the source directory. It sometimes irritates and wastes lots of time.

I have come across this situation and want to avoid re-entry the change directory command.

Environment,

I use the command prompt and PowerShell, which are pinned to the taskbar of Windows.

Change default directory of Windows Command Prompt

1. Right-click on the taskbar pinned Command Prompt icon
2. Right-click on the "Command Prompt" menu
3. Select the "Properties" item
4. Under the "Shortcut" tab, you will find the "Start in:" label
5. In the respective text box, enter the path you want to navigate by default.
6. For example, "C:\Projects".

Change default directory of Windows PowerShell

1. Open the PowerShell with administrator privileges
2. Create a profile by using the following steps

New-item -type file -force $Profile

3. This will create a file "Microsoft.PowerShell_profile.ps1" in the current user documents PowerShell folder.
1. Syntax

C:\Users\<UserName>\Documents\WindowsPowerShell

2. Example

C:\Users\PSR\Documents\WindowsPowerShell

4. Edit file

notepad.exe $Profile

5. Change the default directory
1. Syntax

Set-Location <Directory Path>

2. Example

Set-Location C:\Projects

Clear-Host # To clear the PowerShell screen

6. Save and close the file
7. In the PowerShell window, enter the following command to change the profile

. $Profile

8. It immediately changes from the current directory to the updated default directory.
9. Close the PowerShell and try to open the PowerShell again to see the change in the directory.

Hope the above information is helpful to you reduce the change directories in day-to-day life.

Change IP Address and DNS from static to DHCP and vice versa in Windows Command Line Dynamically using Batch file script

Hi friends,

I was frequently changing my system network from static to dynamic.

I was fed-up with the manual changes by entering the static IP address and changing it to dynamic.

I though of creating a batch file, which requests user to select options and proceed further.

 

I found something on Internet, just modified it for my purpose and thought of sharing with you all.

 

• Check your network name
• cmd> netsh interface show interface
• It will list all the network interfaces connected to your system
• Select the network which you want to change the settings
• Modify the below code with appropriate network name, IP address, subnet, gateway and DNS server

@echo off

set NETWORK="Local Area Connection"
set IP=10.9.40.95
set SUBNET=255.255.255.0
set GATEWAY=10.9.40.47
set DNSSERVER=192.168.178.1

echo Choose:
echo [S] Set Static IP
echo [D] Set DHCP
echo.

:choice
SET /P C=[S,D]?
for %%? in (S) do if /I "%C%"=="%%?" goto S
for %%? in (D) do if /I "%C%"=="%%?" goto D
goto choice

:S
@echo off
echo "Setting Static IP Address, Subnet Mask and DNS Server"
netsh interface ip set address %NETWORK% static %IP% %SUBNET% %GATEWAY% 1
netsh interface ip set dnsservers %NETWORK% static %DNSSERVER% primary
netsh interface ip show config
pause
goto end

:D
@echo off
echo "Resetting IP Address, Subnet Mask and DNS server For DHCP"
netsh interface ip set address name=%NETWORK% dhcp
netsh interface ip set dns %NETWORK% dhcp
ipconfig /renew

echo "New IP Address, Subnet Mast and DNS Server for %computername%:"
netsh interface ip show config
pause
goto end

:end

Now enjoy the feature of changing IP address with 3 clicks
