Setting the default application for a file extension in Windows 10
When you click on a file in Microsoft Windows, the operating system opens the
file with whatever application, if any, that has been set as the default
application to open files with the
filename extension on the file. The file extension is a dot at the end of
the file name followed by a sequence of other characters, often 3 characters,
e.g. for myfile.doc, the extension is .doc. If some program has changed the
default setting on a file type so that it now opens files with the relevant
extension, but you want to revert to the application that previously opened
those types of files, you can do so on a Microsoft Windows 10 system by taking
the following steps:
- Right-click on the Windows Start button, usually in the lower, left-h
and corner of the screen, then click on Settings.
- From the Settings window, click on Apps.
- Click on Default apps.
- In the Default apps window, scroll down until you see Choose
default apps by file type and click on that text.
- Scroll down the list of file types until you see the one for which you wish
to change the default application, e.g., .doc.
- Click on the the icon for the current default application shown to the
right of the file type. You will then be able to choose another application to
become the default application for opening files of that type, e.g., Microsoft
Word for .doc files.
- You can then close the Settings window by clicking on the
"X" at the upper, right-hand corner of the window.

Somone else is still using this PC
I connected remotely to a Microsoft Windows 10 system using the
Remote Desktop Protocol (RDP). I updated some software on the system which
required a reboot, so I clicked on the Windows Start button and chose to
restart the system, however I saw the message "Someone else is still using
this PC. If you restart now, they could lose unsaved work." There was a
"Restart anyway" button, but, since it was late on a Sunday night, I didn't
think anyone else should be accessing the system.

Data loss provided by Microsoft's security "feature"
I was reminded tonight why one should avoid using Microsoft's latest
desktop operating system, Windows 10, for any critical system. I had
postponed some work on a Microsoft Windows 10 system that I was connected
to by a Remote Desktop Protocol (RDP)
connection. I had been working
on the system a few days ago and returned to using the connection this
evening only to see the system was going to reboot in a few minutes for
an automatic update. I often have many applications and windows open at
once and I knew there wasn't enough time for me to save all of my work,
but I thought, even though I only had a few minutes remaining until the
forced reboot, that I could at least postpone the reboot until tomorrow evening
using the steps at
Changing the time for a Windows 10 automatic restart
that I've used before
to postpone the forced reboot due to a software update. However, tonight
when I got to the Windows Update settings window where a "Restart
now" button appears, I was not able to click on "Change active hours"
because that option did not appear under the "Restart now" button. I
frantically tried to find another alternative. I thought, perhaps,
I could hibernate the system to save the work in progress, but it was
too late; the system rebooted and I lost all of the work in progress,
much of which I'll be unable to recreate, since it had been several days
since I had been working on the system and I now can't rememeber what I
had put in some open Notepad windows, etc.
I understand the need to update systems to install security patches
to prevent malware attacks, etc., but I've never lost data on this system
over the course of several years due to such issues. I've only lost data
due to Microsoft's automatic reboot "security feature".
I've read Microsoft is deigning to give their users a little more
control over reboots due to automatic updates with the release of
the Windows 10 "Creator's Edition" in April of 2017, e.g., see
Windows 10 now prevents random reboots during updates, but Microsoft's
decision that rebooting a system while a user is working on it even
when there are open unsaved files, because Microsoft has decided that
"this is for your own protection and too bad if you lose data" gives me
a much more negative view of the company and its products. And I know there
are many others similarly angered at the company after losing work to
these forced reboots in Windows 10.

Determining which version of Windows 10 is installed
There have been various iterations of Microsoft Windows 10 since it was
first released. Though you might think of Windows 10 as one version
compared to Windows XP, Vista, 7, 8, etc., but there are versions of
Windows 10 itself and "builds" within those versions.
You can determine which version of Microsoft Windows 10 is installed on a
system running Windows 10 by typing
"Ask me anything" field. You will then see a window, such as the
one below, displaying the version and build number of the operating system.
In the example shown below from a Dell laptop, the system is running Version
1511 build 10586.713 of the Windows 10
operating system (OS)
, which is the
"November Update" to the OS

Changing the Windows 10 proxy server settings
You can view or change the
settings for a Microsoft Windows 10 system by
using the Microsoft Edge
browser to manage the proxy server settings
or you can do it from a
command line interface (CLI)
, i.e., a
, using the
determine whether the system is currently configured to use a proxy server,
you can use the reg query
C:\> reg query "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyEnable
ProxyEnable REG_DWORD 0x0
hexadecimal value zero and that value indicates the system is not currently
configured to use a proxy server. A value of one, i.e.,
indicates it is currently configured to use a proxy server.
Even if the value is 0, you can determine if a proxy server had previously
been set that will be used again if you set the value to 1 by using the
reg query command below.
C:\>reg query "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyServer
ProxyServer REG_SZ socks=127.0.0.1:1080
In the example above, if the value is set to 1, i.e., the system is
reconfigured to use a proxy server, a
SOCKS proxy server will
be used that is listening on the
127.0.0.1 on the SOCKS proxy
i.e., TCP port 1080. E.g., a
SOCKS proxy could be set up with PuTTY, a free
Secure Shell (SSH)
To enable a proxy server, a reg
add command can be used as shown below.
C:\>reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyEnable /t REG_DWORD /d 1 /f
The operation completed successfully.
In the example above, since the proxy server setting was set to be a
SOCKS proxy, any browser, such as Edge or
Firefox, if it was
configured to use the system wide proxy settings, would now route web traffic
through the proxy server.
