Change the listening port for RDP on your computer- Windows 10, Windows 8.1, Windows 8, Windows Server 2019, Windows Server 2016, Windows Server 2012 R2, Windows Server 2008 R2

When you connect to a computer (either a Windows client or Windows Server) through the Remote Desktop client, the Remote Desktop feature on your computer “hears” the connection request through a defined listening port (3389 by default). You can change that listening port on Windows computers by modifying the registry.

  1. Start the registry editor. (Type regedit in the Search box.)
  2. Navigate to the following registry subkey: KEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp\PortNumber
  3. Click Edit > Modify, and then click Decimal.
  4. Type the new port number, and then click OK.
  5. Close the registry editor, and restart your computer.

The next time you connect to this computer by using the Remote Desktop connection, you must type the new port. If you’re using a firewall, make sure to configure your firewall to permit connections to the new port number.

Enable WIndows Photo Viewer in Windows 10

Default windows “Photo” app is clumsy at some point, missed the earlier “Photo Viewer” program. So, going back to root and after googling, here’s a small hack to enable “Windows Photo Viewer” in windows 10 edition.

  1. Download the photo.zip and unzip it. You’ll get a photo.reg file. The file is created from this forum http://www.tenforums.com/software-apps/8930-windows-photo-viewer-gone-2.html#post290818 
  2. Double-click on your new REG file to merge it with your Windows Registry. You will need to click through the User Account Control and a few other windows to allow the file to make changes to the Registry.
  3. Basically you are done.
  4. Next what you need is to right click on any JPEG/JPG/BMP/PNG/GIF file that you want open/view using legacy windows photo viewer and make it as default.

Windows 10 Saving Spotlight Images

The most aesthetic part of windows 10 is the spotlight images on login screen. Few of them were really too mind blowing that I wanted to save and keep it as a wallpaper! So, here’s the hack on how to do it-

Navigate to the following folder (or just copy the path below and paste it into the File Explorer address bar):

%userprofile%\AppData\Local\Packages\Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy\LocalState\Assets

Note that the %userprofile% part of that path automatically jumps you to the user folder for the currently logged in user (by default at C:\Users\<username> ). In the folder, you’re going to see a whole bunch of files with long, meaningless file names and no extensions. Some of these are the image files you’re looking for; many are not.

How to install Legacy Photoshop 7 on windows 10

Regarding the OP’s problem, it appears the installer exe requires to use resources held by other processes. For me it was Skype and Logitech wireless mouse software.

To work out what is “blocking” the installer:

  • start  task manager, you’ll see setup.exe running as a background process but consuming no CPU cycles.
  • click on the “Details” tab in task manager
  • scroll down to setup.exe, right click on it and select “Analyse wait chain”
  • close the program / end the process which setup is waiting on

You may have to repeat steps 3 & 4 if there are multiple contentions. For me once I killed Skype & Logitech processes the installer popped up instantly. Also I ran setup.exe as administrator

Converting laptop into a wifi router

Well, first assuming, that the laptop has 2 NIC- one with an ethernet port for wired and the other- of course the Wifi ethernet (without this presume this content won’t exist otherwise 😉 )

Now, the next thing- either you get internet from the wired port or to be in some case, you may connect your android phone as wireless tethering and connect through mobile data service. Whatever the case- you basically got 2 interface for setting up the router- the WAN (either the wired or the mobile tethered connection) and the LAN- the wifi ethernet.

This document works good on Windows 7 and 8 (I didn’t test other editions of windows- hope they support too) Continue reading “Converting laptop into a wifi router” »
