Windows provides a number of recovery tools that can help you recover from problems with Windows. Try these recovery methods first, then move to a clean install (wiping the computer and reinstalling everything) if you're unable to recover your computer. File recovery differs between Windows versions.
Recovery from a severe crash or system instability that won't allow Windows to load correctly requires advanced knowledge when using these tools. If you're uncomfortable with this process, get a local computer service to do this for you.

Develop a recovery strategy before your computer fails. Even a basic plan is better than no plan at all.
Be sure to print your computer's instructions on how to recover a non-functioning computer. If you can't access your computer you won't have access to that documentation.
While another computer or device may allow access to the Internet, you must know exact details about your computer's hardware and operating system to obtain documentation online. You must also have access to any documentation proprietary to the disabled device.
Recovery partitions have replaced recovery media in today's computers.
It is critical that you create these recovery media using the manufacturer's instructions.
Some manufacturers (like HP) will only let you create the recovery media once.
Once created, label them clearly and save them in a safe place.
Recovery media will generally offer two options:
A factory restore will wipe the drive and remove all applications and data that didn't come with the computer.
Windows 10 and 11 built-in recovery options allow you to:
Be sure to keep a recent backup of all your important data. Having your data and program settings backed up will give you more options, especially if you have to call upon a professional to restore your system.
The only way to ensure that you can recover your data and programs is to have a recent and reliable backup of your data (photos, documents, emails, etc.).
Many technicians won't bother to try to recover data, but simply restore your computer to working condition. It takes time to recover data from a non-working system and many folks save files in unusual locations.
Most shops do not bother with backups in order to stay "competitive" and avoid issues with missed data. That places the onus on you to have current backups.
It is strongly recommended that you create a fresh backup prior to doing any procedure which could potentially result in the loss of data (e.g., Windows Update, upgrading Windows, installing a new hard drive).
The more recent and complete your backups, the more likely you'll be able to recover everything you lost in a crash.
See backup & recovery strategies to develop a strategy that suits your requirements.
Modern Windows versions have a recovery function called System Restore.
System Restore keeps track of significant files and settings in Windows, so that you can recover from a corruption in Windows caused by a corrupt installation of software or a driver.
System Restore keeps a series of restore points (a backup of various critical Windows files at a certain time, including registry entries and drivers) in a hidden area on the hard drive.
Windows automatically makes certain restore points, but you can also create a restore point prior to making a change to your system that you might need to undo.
System Restore will neither affect your data nor recover lost data or programs.
It is turned off by default in Windows 10 and 11, so enable it so that you have this option when disaster strikes.
Click Start ⇒ Settings ⇒ System ⇒ About then select System Protection from the menu on the right.
Ensure that System Restore is enabled so that you can restore Windows if there is a problem in the future.
While Windows will automatically create restore points for many things, you may wish to create one manually:
You can use System Restore to return your system to a state before a problematic driver was loaded or your Windows Registry was corrupted. Be sure to close all running programs before starting System Restore.
You can only use System Restore on the drives where it is enabled via the Configure button.
The following resources can help you with this process:
Safe Mode starts a minimal Windows environment with only the essential drivers and files are loaded. Video resolution is greatly reduced and startup programs are not launched.
Some of the reasons you may enter Safe Mode include:
Windows 8 and later were designed to run on the UEFI boot environment rather than the BIOS system used in earlier computers so the process is a little different.
Windows 11 adds the requirement for TPM 2.0 in a secure boot environment.
The Shift+F8 key combination will NOT work in recent versions of Windows.
Try pressing the Shift+F8 key combination or just hold the Shift key and click Restart from within Windows (or at the login screen).
Other boot options are available on the Advanced Options Menu, including:
Additional options exist, but most users are unable to take advantage of them.
Each Windows version has some sort of a bootable recovery option or disk. See Recovering Windows.
If you don't have the ability to recover your computers operating system and programs you'll need to perform a clean install.
If your computer came with a Windows 10 licence (or you upgraded from an earlier version of Windows) you'll need to know where your licence is for a clean install although if the hardware is the same, the license is recorded on Microsoft's activation servers.
This is usually a last resort when all other recovery methods have failed, but a clean install can also resolve accumulated performance problems.
Performing a clean install involves these steps:
This is a relatively involved process which will remove any programs which didn't come with your operating system as well as your data. Backups are essential.
Fortunately, Windows 10 and 11 has made this process much easier.
The “Reset Your PC” feature in Windows 10 restores your PC to its factory default settings, including all that bloatware your PC manufacturer included.

Fresh start removes third-party antivirus software and all apps that don't come standard with Windows.This includes Microsoft apps such as Office, any desktop apps that came preinstalled on your device, and any Windows desktop apps, such as your device manufacturer's apps, support apps, and drivers.
It keeps only Microsoft Store apps that your manufacturer installed.

Be sure you have backups of any data since things can go wrong. The shop is not liable for your data. You know whats important to you and what can be ignored.
A clean install requires you to do some preparation first:
If your computer came with a Windows 10 licence (or you upgraded from an earlier version of Windows) you'll need to know where your licence is for a clean install:
In situations where you're unable to do this (such as a hard drive failure), you may lose all your data and programs — which is why a recent backup is critical if you care about your photos and other data.
Some software providers may provide the ability to reinstall a registered program if you contact their support department and explain that you've lost the ability to recover a functioning Windows installation. If not, you'll need to purchase the program again.
Once you've completed these preparations, you'll need to reinstall Windows.
This process will destroy ALL information currently on the disk.
There are two options available to you:
If possible, try to recover from within Windows first because it gives you the most options to save current settings and data.
Windows 8, 10 and 11 provide the ability to recover Windows from within Windows itself.
Click Start ⇒ Settings ⇒ Update & Security ⇒ Recovery.
There are two situations where you cannot recover from within Windows:
You'll need to boot from installation media then do a clean install:
You'll need to choose the option to install Windows 10 on a different PC using a blank USB flash drive with at least 8GB of space or blank DVD.
The DVD option only works if you have a DVD burner on both the computer you're creating the media on and the computer you're installing Windows on. DVD capability is increasingly rare.
You can also do a clean install using the Windows installation DVD. Vendors seldom provide these.
Choose the custom (advanced) install rather than the upgrade. You'll need to format the existing partitions (at least the current C: partition). Optionally, you'll want to delete all partitions and let Windows create the partitions it needs.
WARNING: deleting or formatting partitions wipes all existing data.
The DVD will copy installation files onto the hard drive then Windows will reboot several times as it completes the install.
During the first reboot you'll want to be sure that the computer boots to the primary hard drive, NOT the Windows DVD.
If your computer came with the operating system you wish to reinstall (e.g., Windows 10), you can use the manufacturer's recovery partition if you have the media.
Like the Windows Installation Disk, you'll boot to the recovery disk and follow instructions.
There is generally at least two options:
This second option is the clean install option during which all existing programs and data will be destroyed.
The computer will be restored to the condition it was when shipped including the original (not updated) versions of programs and will not include any personalization.
Regardless of whether you used the Windows Installation Disk or the Manufacturers Recovery Disk, you will need to do the following once the reinstallation is complete:
I recommend you keep a current list of the software you use on your computer and any licence numbers required in a safe place where you can find them. This will make it easier to recover in situations like this.
Windows 10 & 11 | Windows 8 | Legacy
In addition to the general information contained in the Recovery Tools section, there are recovery options available in all current versions of Windows.
If you are selling or disposing your Windows computer, you should do a clean install.
This will format the drive and install only Windows and its default programs without your personal data and software.
Windows 11 has a built-in recovery option that allows you to reset your computer (keeping your files), go back to an earlier build or advanced setup.
Windows 10 has a built-in recovery option that allows you to reset your computer (keeping your files), go back to an earlier build or advanced setup.
Much like Windows 10, Windows 8 has recovery options that allow you to restore your computer with either the programs and data intact or with a clean install.
If you're using a recovery partition on an older Windows 8.1 computer, it may restore Windows 8. You'll then need to install the update to Windows 8.1.
Instructions for recovering legacy Windows (those unsupported by Microsoft) are archived.
I do NOT recommend running older versions of Windows, especially while connected to the Internet.
New vulnerabilities are often present yet unpatched in older systems.
Most laptops and many name-brand computers don't come with a Windows or drivers CD. Instead they rely upon a hidden recovery partition. To ensure your ability to reinstall Windows, you'll need to create the recovery CDs or DVDs while your system still works then put them in a safe place.
This option varies by manufacturer, but most will depend upon a hidden recovery partition on the primary hard drive plus a DVD or CD recovery disk to start the process.
The recovery partition and the recovery disks are the only sure way to restore Windows and the programs that came with your computer.
Most systems require a special boot disk (created in this process) to access the recovery options.
These recovery disks are your only option if the hard drive fails or if you want to install a new hard drive on your computer. You cannot copy the recovery partition; it must be created using the recovery DVD.
You may be able to order recovery disks from the manufacturer provided they still support your computer.
These are usually expensive and you'll have to await delivery. It can be a long wait if your computer isn't working.
Sometimes you can re-install Windows using an Windows installation DVD — provided the Windows installation DVD is the same version as your licence.
You'll need to download the drivers for your computer model from the manufacturers site.
The same model of computer can be configured with various brands of hardware.
It can be difficult to determine which drivers to install if the system isn't running, especially on a laptop.
You'll need to know the exact drivers for your particular computer.
There is no guarantee that the manufacturer will provide access to the drivers for older versions of Windows.
I recommend storing the drivers for your model on a removable device in case you need them later.
