Why does the Windows registry exist? [closed]
location: linuxexchange.com - date: September 20, 2014
this is more OS architecture question than programming directly, but still. Why was the Windows registry created as a completely separate subsystem for storing system/application settings? In *nix OS'es there is /etc directory which is perfectly understandable, as filesystem is a natural hierarchical way for storing settings, while Microsoft decided to create a completely outside hierarchical subsystem, which seems to be a foolish investment, why didn't they just use a filesystem hierarchy?
Why does Windows slow down eventually

I've experienced that all Windows eventually slow down until their speed is half or quarter their original speed. Why does this happen?
Why does Windows slow down your computer?

Why does Windows slow down you computer over time but other OS don't?
I'm just asking out of curiosity. I'm not asking how to speed it up, just why it does that.
Why does Windows only show about 3.5 GB of my more than 4 GB of RAM?
location: linuxexchange.com - date: August 18, 2012
I recently upgraded my computer's RAM to 4 GB. My 32-bit Windows installation shows only 3574 MB of the memory. How can I make Windows use the full amount of RAM?
When viewing an Applet, why does Safari for Windows display “Java is Unavailable or Not Installed” when Java is installed and available? [closed]
location: linuxexchange.com - date: July 26, 2013
When using Safari on Windows 7 to load any page containing any Java applet, the following alert appears:
"Java is Unavailable or Not Installed. Do you want to go to a page where you can download java?"
This message is incorrect. These are developer machines with one or more instances of the Java JRE / JDK installed, including 1.7.x. Many alerts are accompanied by messages referencing a non-existent file path, similar to:
"The Java Runtime Environment cannot be loaded from
The following attempts to repair the situation have all failed:
Uninstalling and re-installing various Java versions.
Updating to the latest Java version.
Changing security settings in Safari.
Going to http://www.java.com/en/download/help/testvm.xml detects an obtuse version that is not even installed (Java 2 Runtime Environment, SE v1.4.2_19 ?!?!)
Searching the internet reveals many users with similar problems, but no answers.

FAQ: Why does my time in Windows keep getting reset to UTC?
location: ubuntuforums.com - date: November 27, 2004
Ubuntu assumes by default that the system clock is set to UTC. To change this behavior:
sudo gedit /etc/default/rcS
Find the line UTC=yes
Change it to UTC=no
Save the file.
The next time you reboot to Windows, your time will be correct. (Assuming that the time in Ubuntu was correct when you edited the file)

why does MEPIS miss my Windows partition?
location: linuxquestions.com - date: August 9, 2006
My MEPIS is working very well, but all three times I've installed it, it's had a very peculiar quirk regarding its ability to read the Windows partition. In Konqueror, if I try to access the Windows partition from /mnt, it opens the partition but always initially claims there is nothing there. "0 Files, 0 Folders." Uh...what?? A couple of times I've let it sit, and after ten-to-fifteen minutes, the files and folders belatedly appear.
However, I found an easy way to get around this, which makes it even stranger. If I avoid /mnt, and click on the floppy drive link on the desktop, I can view "4.7 GB Media" (this Linux partition) and "7.3 GB Media" (Windows partition). If I open the 7.3 GB media, MEPIS finds the files and folders partition without a problem.
I think this oddity is not indigenous to MEPIS. When I briefly tried Fedora Core in June (whatever the latest release was), something similar happened. But then, MEPIS is the only distro I'm interested in
Why does this simple Java program work correctly under Windows but not Fedora 10?
location: linuxquestions.com - date: July 29, 2009
I have written the following little framework for a game I was hoping to write for Linux. This works fine with the same version of the JDK on Windows - a black screened window with a frames-per-second readout on the top left, but this fails to work under Fedora 10. I have installed Sun's official JDK and all I get is the Swing window which is the default grey and nothing else.
Why does linux performance seem so terrible in comparison to windows?
location: linuxquestions.com - date: April 27, 2005
I'm not trying to start a flame war here, and I'm no advocate for windows, I'm really asking this seriously:
I'm using Mandrake 10.1 (kernel 2.4), and Openbox 3.
I've got an AMD K6-2 processor (400mhz) and 164mb of ram.
I also have an installation of Windows 2000
my question is this: why do linux applications run so much more sluggishly than do windows applications? I understand that windows preloads a lot of stuff, I'm not talking about IE start time vs. firefox start time... in fact, if they both ran at the same speed, I wouldn't care which took longer to load. Firefox runs WAY faster under windows 2000 than it does under linux.
I don't get it. Am I doing something wrong? Isn't linux suposed to run faster than, or at least at a comparable speed to windows?
