If you are upgrading to Windows 10 then you won't loose any of your files.

You may follow step by step upgrade process of Windows 7 to Windows 10 from Microsoft. This will help you and will answer any of your concerns.

Well there is not much in steps above from Microsoft, its just you reserve your copy, your existing windows will download a copy automatically for you and will prompt you once it is ready to install.

hi you can use the windows 10 media creation tool to upgrade. see the link below. do a backup beforehand, as this is always good practice

what happens when you upgrade is windows creates a folder named windows.old

within this folder you will find the users folder and your user account folder will be there

Windows creates a new folder for your Windows 10 account then you will need to copy any files you wish from the windows.old users folder to your new users account folder.

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

Hi tjie,

The following steps should help you

1. Ensure that your computer has the internet & the Genuine Windows 7 OS is updated with the latest patches (If not Update).
2. Go to RUN & type regedit
3. Computers\HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate
4. Check for the OSUpgrade Key & if not found create the same & type in the binary value AllowOSUpgrade & Provide Hexadecimal value 1. (Refer attached Snapshot for the registry key value settings)

Let me know if you require any more support on this.

Hi tjie,

Two suggestions:

(1) Read John's excellent EE article about upgrading to W10:
Upgrading older systems to Windows 10 - a real world test

(2) You may want to consider disabling the Windows Update Delivery Optimization (WUDO) feature (peer-to-peer updating), as described in my EE article:
Windows 10 uses YOUR computer to help distribute itself

Regards, Joe
Just a small addition about Thomas' comment: No, you'll not need to copy anything over, that's what upgrading is about. Make a backup anyway.

Download the free backup tool from Paragon -Backup & Recovery:
Create backup to external drive.
Then download Media Creation Tool from Microsoft and start it. Select first option and it will perform upgrade.

Upgrading to windows 10 generally doesn't damage any files on the system, during the upgrade you should be carefully with the antivirus softwares if any as some versions doesn't support windows 10. In this case you will have to uninstall the antivirus and complete the upgrade to windows 10. In my case I had problem with Symantec antivirus 12.1.15 not supporting and had to uninstall the same after the upgrade I installed Symantec 12.1.16 which supports windows 10. Iam in a domain environment and didn't face any issues during the upgrade. I found all my software and data  and applications running fine during the upgrade,  the upgrade was carried across 5 computers in the domain network.

even if it is not needed - make abackup before you start
you never know if there won't be problems down the road...and then you're sorry for not having a backup (all systems should have a regular backup)
ANUPKUMAR NAIRManager IT InfrastructureCommented:
Right said Guys, Its always safe to have a backup done before the upgrade, also try to gets confirmed with the application vendor if you are using some customized software which works only on windows 7 platform.
All the above-mentioned items are correct - you should make a backup FIRST, before doing anything else in regards to the upgrade to Windows 10. However, what no one seems to have mentioned is the number of installs where things seem to get "lost". Most of these users fear that they have lost everything - but what has happened is that the Windows installation process has moved the files to a different and sometimes "hidden" location. There does not seem to be much rhyme or reason to the process.
     See this ongoing drama unfold -
     People have found their data in a /network folder, other drive partition folder and in hidden folders. Some people are also confused by being logged in as administrators when they should be logged in as a user.
     Yes, a backup is a good thing! (Saves heart failure.)
