learn how to use and install windows in PC's or desktop.
Step 1: Purchase Windows
Parallels Desktop for Mac does not include Microsoft Windows. If you don’t have a Windows copy, you can purchase Windows 10 from the Microsoft Online Store:
Buy Windows 10 Home
Buy Windows 10 Pro
Note: visit this page if you need help to choose Windows 10 edition: Home or Pro.
After the purchase please visit the Download Windows 10 page to create your own installation media and the Windows 10 page to learn more about upgrade from previous Windows versions.
For earlier versions of Windows, please refer to retail stores or authorized online resellers, including Amazon.com.
Step 2: Create a new virtual machine
In the Applications folder open Parallels Desktop and choose File > New.

Step 3: Select the installation media
You may install Windows from a DVD or an .iso disc image, or a bootable USB drive.
Important: Windows installation files with an .exe extension can be used only to upgrade an existing Windows virtual machine (VM). If you are performing a new install to create a new Windows VM, the .exe installation file will not work. Please contact a retailer to request either a physical disc or an .iso image.
Parallels Wizard will detect the installation media automatically for installing Windows.
You can also switch to manual mode and choose the source for Windows installation.
Step 4: Enter your Windows product key
Click Continue. In the Windows Product Key window, leave Express installation selected.
Note: If you uncheck Express installation, you will need to install Parallels Tools manually after the Windows installation.
When you are ready, click Continue.
Step 5: Select how you want to use Windows
Select how you want to use Windows in Parallels Desktop for Mac:
Productivity
Games only
And in Parallels Desktop for Mac Pro and Business Edition:
Software development
Software testing
Design
To learn more about virtual machine profiles, visit KB 123878.
Step 6: Specify a name and location
Name: You may specify a name for your virtual machine.
Location: The default location for Parallels Desktop virtual machines is /Users/username/Documents/Parallels.
If you want other user accounts on your Mac to have access to this installation of Windows, select "Share with other users of this Mac".
If you want to change your default virtual machine settings select Customize settings before installation. These settings can also be changed easily after installation.
Step 7: Begin the installation
Click Continue and Windows installation will begin. Once Windows is installed, launch it by opening a Windows application or by clicking the Power button in the Parallels Virtual Machines list.
Important: The first time you start Windows, Parallels Tools will be installed to allow seamless operation between Windows and OS X. Please do not cancel or stop the installation process. Once the Parallels Tools are installed, you will be prompted to restart Windows.
Troubleshooting
If you have any problems installing Windows from a DVD, or if you don't have a DVD drive, you can use another drive to create an .iso image and install from that. For instructions, see KB 4917: How to create an .iso image from a Windows installation DVD.

For the past few weeks, I have been trying to install the latest windows security update onto my custom built PC. Every time I tried to update it would reach a certain point and then give me the error message "Unable to Complete Update, Undoing Changes" ( or whatever it says there). It gave me no information as to why it failed every time, but I got tired of having to restart my computer all of the time so I began actively trying to solve the problem.
First thing I tried:
Downloaded the standalone installer, ensured that my internet was not set to metered connection (since that can prevent some updates from installing) and tried again. Same thing, update failed.
I ran the Windows Update Troubleshooter. It found a few errors and fixed all of them but one. I don't remember precisely what the error was, but I was something security related. After going through the list on the Microsoft website ( https://support.microsoft.com/en-ca/help/10164/fix-windows-update-errors ) and made it through to option 4. When I tried to run the sfc /scannow command, it told me that the scan could not be completed. For me, the next logical step was to reboot into safe mode and try to run the scan there.
I went in and set my computer to boot in safe mode, then restarted my computer. I got to the screen with the blue windows icon and that's where it stayed. I used the restart button on my computer and it brought me to the advanced startup page after displaying the logo screen with text at the bottom saying "Diagnosing Your P.C."
Things I have tried and what the result was:
Restart: Freezes at the Windows icon screen
Continue and Exit to Windows 10: Freezes at the Windows icon screen
System Image Recovery: Windows can not find a system image on this computer. (I have never created one)
Startup Repair: "Checking disk for errors..." "Attempting repairs" "Startup Repair couldn't repair your PC. Press 'Advanced Options' to try other options to repair your PC or 'Shut Down' to turn off your PC. Log file: E:\Windows\System32\Logfiles\Srt\SrtTrail.txt"
Command Prompt (from advanced options): sfc /scannow yielded the same result, not sure what else to try.
Go back to the previous build: "We ran into a problem and won't be able to take you back to the previous bud. Try resetting your current build instead."
Enable debugging: Stuck at Windows icon.
Any version of Safe Mode from the Startup Settings: Stuck at Windows icon
Clear CMOS and try everything again: no change
Disable overclocking and try everything again: no change
Switch to Bios B (dual boot) because why not and try everything again: no change
Reseat ram: no change
I would re-install windows, but there are a few things that I do not want to lose (mainly game files in things I've been working on for years) that I fear will be lost when the operating system is uninstalled.
