How to free space in SSD on window 7

After installation of window 7 in computer with SSD and high RAM you may notice high usage of disk space than normal.This happens to me when i was installing window 7 on 100GB SSD drive with 16GB of RAM, i noticed installation took almost 40GB which is not normal at all for window 7, below is how i did to restore my space.


This is how my C look after installation but before space recovery:

Decrease the size of page file/Virtual Memory
Window as in Linux it allocates part of your hard drive as page file or virtual memory for the aim of increasing the performance of your computer, but if you have more than 4 GB of RAM this is useless, for me it allocates 16 GB of my hard drive as virtual memory, so the best way is to minimize it to 1024 Mb to 512 Mb by following the steps below:

-Click the Start button, right click Computer and then click Properties
-In the left pane click Advanced system settings
-In the window that opens click the Settings button in the Performance group box and select the Advanced tab page.
-Click the Change button and select the drive where you page file currently is (by default C:)
Select Custom size and fill the initial and maximum size of your page file to be the same amount of space
512 MB /1024 MB is more than enough if you have more than 4 GB of RAM When ready click Set and then OK.

By doing that it free most of my hard drive space, see below after performing the step above and restart computer.

Hope it helps someone, enjoy.

Solved!!! The problem of wifi disconnection in Dell Latitude 7450 (7000 Series) when using Ubuntu/Deepin Linux

Friend of mine bought dell latitude 7450 which came with window 8 Pro, but because the guy is in love with Linux he installed Deepin Linux (http://www.deepin.org/) a linux distro based on Ubuntu, soon after installation he started facing problem of wifi disconnection which was so bad as sometimes the wifi forgets the password so he was supposed to retype the password every time it disconnects.
We take as challenge, and starting working with on it, where we discovered that the computer come with Intel Wireless 7265 card which has problem of loading the wifi driver in Ubuntu and all Ubuntu derivative distros.
The solution is to reinstall the drivers manually, by following the below two simple steps.

1. Download the kernel driver from this link (https://www.kernel.org/pub/linux/kernel/projects/backports/stable/v3.18.1/backports-3.18.1-1.tar.xz), although the driver is based on kernel version 3.18 but it works well also for kernel 3.13 ,and save it to desktop, then run the following commands,

sudo apt-get install linux-headers-generic build-essential
cd ~/Desktop/backports-3.18.1-1
make defconfig-iwlwifi
make
sudo make install

2. Download the firmware from the following link (https://wireless.wiki.kernel.org/en/users/Drivers/iwlwifi#Firmware), from documentation they suggested to use -9 for kernel version 3.17 but because we have kernel version 3.13 we downloaded both -8,9 and 10, download them on Download folder and extract then run the following commands,

cd ~/Downloads/iwlwifi-7265-ucode-23.11.10.0
sudo mv iwlwifi*  /lib/firmware

cd ~/Downloads/iwlwifi-7265-ucode-25.228.9.0
sudo mv iwlwifi*  /lib/firmware

cd    ~/Downloads/iwlwifi-7265-ucode-22.24.8.0
sudo mv iwlwifi* /lib/firmware

sudo chmod 644 /lib/firmware/iwl*

Reboot your computer for the change to take effect.


Problem solved, Enjoy!
