Microsoft Office Programs laggy when dragging with mouse

Problem: When clicking and dragging Office Programs by the title bar, the window is slow to move and respond to the mouse location.

Resolution: The problems appears to be related to the USB polling frequency for the mouse. Look at the mouse settings and try reducing the polling frequency. And/or try another mouse.

Windows 10 – Super slow copy speeds

It looks like the Windows Defender Real-time protection can cause issues when trying to copy files on a local drive even if the drive is an SSD.  Typically a copy seems to start out great, but then slows down to a crawl less then 1MB/s copy rate.  Probably has to do with Defender having to scan every file as it is copied.

To fix/increase the copy speeds you can turn off Real-time protection.

To turn off Windows Defender Real-time protection, open up Settings > Update and Security > Windows Security > Virus & threat protection “That should open up the Windows Defender Security Center” > Virus & threat protection settings

Now Turn Real-time protection off.

 

Setting up Proxy over SSH with Putty on Windows

What we are going to do is create a proxy using ssh so we can tunnel our web traffic in Firefox through it.

First, launch putty and setup a SSH connection like you normally would.

Next, in Putty, go to the Connection, SSH, Tunnels.  Set source port, change to Dynamic, and add.  In this example we are using port 1880.

After you have it set, Open the connection and log in.

Now go to the Proxy settings in Firefox.  You can open new tab, type about:preferences, hit enter, search proxy.

Set to Manual proxy configuration, then under SOCKS Host put localhost and the port number from Putty above, 1880 in our case.

You should now be running over the proxy, can test by running a whats my ip address.

This can be particularly useful in cases where you need to access a local IP address range on something like a Ubiquiti radio or router.  Or you need to check something from a different IP address.

How to Find System Uptime in Windows

There are a few different ways to view the system uptime.   either the Task Manager or the Command Prompt.

Task Manager

Launch the Task manager by using the Ctrl+Shift+ESC Shortcut keys, Right clicking on the Task Bar, or by searching and launching from the start menu.

Go to the Performance tab, view Up time at the bottom (On Windows 10 you may need to hit More “details first”

 

Command Prompt

Launch the Command Prompt.  Can do this by clicking start and searching for cmd.

Then run

 systeminfo | find "System Boot Time"

It’ll show you when the system last started up.

Example:

C:\Users\Owner>systeminfo | find "System Boot Time"
System Boot Time: 6/21/2018, 3:45:12 AM

C:\Users\Owner>

Add local DNS entry in Windows

Windows has a similar file like the Linux /etc/hosts file.  It is located in

Windows\System32\drivers\etc\hosts

You’ll need to have administrator privileges to modify the file.  So you can launch notepad as Administrator then open the file.  If you don’t see the file make sure the drop down across from “File name:” is set to “All Files”.

You can add entry’s just like you would on Linux

192.168.22.12   hostname

How to replace Grub with default Windows Bootloader

Note that running this procedure could render any Linux partitions inaccessible.

Boot up into recovery, launch the Command Prompt and run the following command

BootRe.exe /fixmbr

The command should remove Grub and replace it with the Windows bootloader, so when you reboot it should go straight to Windows.

Other Issues

Windows 10 seems to be a little weird when you have two installs on two different drives and your trying to repair one.  I have had issues when trying to repair one, or boot into safe mode.  Removing all other other drives seems to resolve most of the issues.

Issues with multiple drives with an install of Windows 10

  • Reset Drive resets the wrong drive
  • Boot into safemode doesn’t work
