How To Factory Reset Windows To Its Default Settings

If you’re having trouble with your Windows PC or planning to give it away or sell it, you may want to reset it to factory settings to erase your data. A full factory reset erases all your apps, settings, and files to return it to the way it was when you first purchased it. It’s a quick way to start from scratch.

Note: a Windows factory reset is a good way to fix many drive update issues and registry errors. However, you have to be patient, as the process can consume a lot of time, so allocate at least a few hours for this activity. This works for both Windows 10 and 11.

Note: factory resetting your Windows PC should be treated as the last option. It is best to troubleshoot the issues first, be it a Windows Store error, Windows update issues, or a Bad System Config error. Only reset the PC if none of the solutions work.

Back Up Your Data

A Windows factory reset erases all your data. This includes pictures, documents, music, etc. Back up all your important files before you perform the reset. You can do this easily by copying your files to an external hard drive, a flash drive, or your favorite cloud service. Alternatively, create a backup to a network drive.

You can simply copy and paste the files you want to keep or do a full system backup – either one will work. Do not make a system copy to another partition on the same hard drive as Windows.

Reset Windows to Factory Defaults

After all your files are safe, it’s time to start the reset process.

Select “Update & Security” in the left pane.

Select whether you want to keep or remove files. If you choose “Keep my files,” Windows attempts to reset everything but preserves personal files. It will delete any apps and app settings, though. If you choose “Remove everything,” Windows deletes everything. It’s best to delete everything if you’re having trouble or selling/donating/giving away your PC.

Choose whether to reinstall Windows with a local copy (this may be a recovery partition or physical media) or a cloud download.

Select custom installation options. These will vary slightly based on other options you’ve chosen. You’ll see things like “Clean data,” “Download Windows,” whether to wipe all drives or just the Windows drive, and whether to reinstall the preinstalled apps with your PC.

The PC will reset in the background. The exact time varies greatly based on the size of your hard drive and what type of reset you chose. For instance, deleting everything and installing all preinstalled apps will take longer. If you have a slower Internet connection, choosing to download Windows will also add to the time.

Advanced Startup “Reset” Method

Another option is to reset the Windows PC in Safe mode. This is preferred if you are stuck infinitely in the “Prepare to reset” option in the above section. It is mostly a GUI error. The same procedure is used in safe mode, but the steps are slightly different, as shown below.

To reset Windows in Safe mode:

Go to “Advanced Startup” in the Start menu. Once the blue screen starts, go to “Troubleshooting” followed by “Reset this PC.” You will get a choice to reset only the driver where Windows is installed or all drives. Choose the latter for a complete reset.

You will get the choice to “fully clean the drive” or just “remove the files.”

After the Reset Finishes

Once the reset finishes, you’ll receive the same prompts to set up your PC as you did when you first bought it. This includes setting up your network, setting your time zone, and various personal settings. Go step by step through these screens to get Windows back to the way it was.

Before you add your files, install all Windows updates. When you factory reset Windows, it also removes all updates that didn’t come with the original installation.

Press Win + I to open Settings.

Select “Update & Security.”

Choose “Windows Update.”

Search for updates and install all that you find. You’ll likely need to repeat this process several times to get them all. The process can take a few hours, depending on how much you need to install.

Finally, reinstall any apps that didn’t come with Windows that you use regularly. These may include games, productivity apps, photo editors, antivirus, etc.

Once everything else is set up, it’s time to copy your files over. If you did a system backup, you can use this versus having to reinstall all your apps.

Frequently Asked Questions Will a factory reset remove viruses?

Yes. However, if you don’t delete all the files, it’s possible the virus will still be attached to your files. Scan your backup drive for viruses before copying your files to the PC.

Why are some of my files missing if I chose to keep personal files during the reset?

While Windows usually does a good job of retaining your personal files, sometimes they do get deleted or corrupted during the process. This is why it’s important to make a full backup before doing a reset.

Will Businesses Ever Return To The Office?

Did You Know?

A telecommuting policy should address who is eligible to work from home, set expectations about hours, and help workers set up a secure home office.

Key Takeaway

Cloud computing facilitated the rise of remote work by allowing users to access files and specialized applications as if they were in the office.

Advantages of returning to the office

The “new normal” way of working — allowing employees to work in various environments — has benefitted many businesses and their employees. However, returning to the office also has unique perks.

Here are some benefits of returning to an in-office setup that may help businesses determine if a return-to-office mandate is what they need to thrive and grow.

1. Returning to office work will reduce distractions. 

Working in an office reduces many of the common productivity-killing distractions that affect a home office. Office environments tend to be quieter, more focused, and more structured than a WFH setup, where kids, neighbors, pets and so on may interrupt workflow. 

Global Car Accessories owner Muhammed Alkhudri agrees that it can be challenging to concentrate at home. “I have tried to work from home, and I still to this day do that sometimes, but the distractions become much more compelling when you work from home,” Alkhudri noted.

While office environments differ, returning to in-office work often means you’ll be in surroundings designed to ensure as few distractions as possible to boost productivity. 


Distracted workers cost businesses time and money, leading to productivity loss, inefficiency and overpayment for labor.

Did You Know?

Having everyone in the same office also offers more opportunities for team-building and camaraderie, which can improve employee engagement, collaboration, productivity and company culture.

Key Takeaway

Research from Ergotron says remote workers are more productive, enjoy an improved work-life balance, and have healthier lifestyles.

Business type and industry are crucial considerations

When exploring whether your company should ask employees to return to working onsite, consider the type of business you run. Remote work isn’t an option for businesses that require in-person, customer-facing employees. If your office frequently welcomes clients, having staff onsite is necessary. 

Other businesses have more flexibility. Let’s say you sell online via an e-commerce shop. You have few storage needs and outsource shipping and order fulfillment to a third party. In this case, bringing employees back to an office may not be necessary. There’s no need to incur the expense of a commercial lease. 

Ultimately, you’ll need to weigh your business’s unique needs and culture before mandating a return to the office. Business owners shouldn’t feel pressured by trends or what other companies are doing. Doing what’s best for your organization — and protecting your employees and resources — is most important. 


Conduct employee surveys to determine how your team feels about working at home vs. returning to the office. Meeting the needs of your top achievers can foster loyalty and employee retention.

Find the right work arrangement for your business

Returning to the office after years of working from home or in a hybrid setup is a huge step. Many businesses can make a case for returning to the office. In fact, this step is inevitable for some. 

However, some organizations may benefit from a hybrid arrangement where some workers report onsite and some work remotely. Offering the best of both worlds may positively impact your employees and the entire organization. 

Business owners must carefully balance the needs of their organization and consider their employees’ best interests before mandating a return to the office. 

Cloud Reset Lets You Reinstall Or Reset Windows 11/10 Via The Cloud Download Option

One of the major drawbacks of recovery or reset without any ISO is when the installation is in a terrible state or is too corrupted. The process will ask you for an ISO if it finds something beyond repair or usable. That is where this latest cloud download option in Reset this PC can help.

Says Microsoft, The cloud download option will reinstall the same build, version, and edition, that is currently installed on your device. This new cloud download option is available to all Windows devices and is different from the “Recover from the cloud” feature available on some earlier Windows devices.

How to reset or reinstall Windows 11 via Cloud Reset

Open Settings.

Choose Windows Update.

Go to Advanced Options.

Choose Recovery tab.

Select the Keep my files or Remove everything option.

Select the Cloud download option.

Select Reset.

That said, once you choose this option, it will not restore the tools, apps, and configuration that came with the original image provided by the manufacturer.

Switch to the right, choose Advanced Options.

Move to Recovery tile under Additional options section.

Hit the Reset this PC button. Choose to Keep my files or Remove everything option.

Following the selection of Keep my files or Remove Everything option, you should see Cloud download or Local reinstall options. The Cloud download option connects to Windows Update over your current network connection.

When you select the Keep my files option, two additional steps will be performed namely –

Preparation phase – It checks all the necessary requirements like whether the Windows Recovery Environment (Windows RE) is present and enabled, find what optional features and languages are installed. It also checks for connectivity with Windows Update and the download size.

Offline phase – when the download completes, the offline phase kicks in by rebooting into Windows RE. It will apply image from the downloaded payload, gathers the user profile from the previous OS and applies it to the new OS. Apart from this, the offline phase will gather drivers from the previous OS, apply optional features/ languages to the new OS, delete the downloaded payload, and reboot into the new OS.

It gathers Drivers

Optional features and languages of the prior installation, and use it to the new one.

Switch OS root folder from the previous OS to the new OS

Delete downloaded payload

Reboot into the new OS, and apply drivers, OEM customization, preinstalled apps.

Reboot to the Out-Of-Box-Experience (OOBE)

(Keep my files) Skip OOBE and proceed to login screen

This will complete Cloud Reset or Reinstall in Windows 10.

Troubleshooting if Cloud reinstall fails

If your computer is not able to boot into Windows, you can reset the computer using the cloud download option from the Windows Recovery Environment (Windows RE). When Windows is unable to boot after two consecutive failed attempts, the device should boot into Windows RE automatically.

If you previously connected over WiFi, then it will still work but will depend on drivers loaded by the PC manufacturer. We always suggest using an Ethernet port if available.

Does Windows 10 Cloud Download look good?

There are a few things still missing in the Cloud download. In case of a connection failure, does it redownload the whole ISO again? Because this has been the primary reason why many prefer to download the ISO and create bootable devices. Does it roll back if there are multiple failures? Does it allow you to use Windows while the download is in progress? It is important for those who don’t have very high-speed internet and download an ISO that can take about 40 minutes.

How long does it take to Reset Windows from the cloud?

It depends on the strength of your Internet connection. On average, it can take 45 minutes to 3 hours depending on the kind of OS you have installed, the speed of the processor, the RAM, and whether you have an HDD or an SSD drive.

Does resetting the PC make it faster?

The answer is yes. A factory reset can make your laptop run faster, though temporarily. This is because, with the passage of time, some temporary files may build up and turn your PC into the same sluggish machine as before.

How Will The Change In Internet Privacy Laws Affect The Www?

At this point we’ve been all around the topic of how our Internet privacy will be affected after the change in the law last month. The House and the Senate in the U.S. voted to give Internet service providers the right to sell and share our web-bowsing data … without our consent. What we haven’t talked about, though, is what effect it will have on computing in the distant future. We asked our writers, “How will the change in Internet privacy laws affect the WWW in the distant future?”

Our Opinion

Our writers all have differing opinions on this matter.

Trevor “sadly” doesn’t think there will be much effect on the Internet as a whole. “There will be a lo of talk, but not many end users will change anything.” Fabio agrees. He thinks “everything will stay the same.”

In the process he believes it will “slowly erode the free and openness of the Web unless there is a backlash on the effort to monetize everything possible.” He figures it’s only a matter of time before the FCC is for sale like Congress and that we”ll no longer have any sort of net neutrality.

Ryan believes “the amount of bad press this issue has received will ultimately influence websites/companies to include disclosures about how they will or won’t use your data.” He believes that users may even have the ability to opt out of data collection, depending on how negative the public’s reaction is. And in the meantime, “VPN providers will pop up like weeds, making it more difficult to sort the wheat from the chaff.”

I think this is all going to indelibly change the WWW in the future. This was taking away a law that was previously passed just a few months ago and wasn’t even enacted yet. And while it may seem that this newer law is just canceling out the other law, people didn’t realize what they stood to lose until now.

This isn’t just setting everything back to where it was a few months ago. It’s now making people panic thinking about what could be shared without their knowledge and making companies realize what they could be gaining. I think it’s going to make users make different choices and lead to companies taking more than they thought to take to begin with.

Which Console Maker Will Win The Next

Which Console Maker Will Win the Next-Generation Battle?

The Nintendo Wii U has kicked off a new generation of consoles. The device, which comes with HD graphics that can about match those we have from the PlayStation 3 and Xbox 360, will likely be joined by vastly more powerful PlayStation 4 and Xbox 720 consoles at some point in the next year or chúng tôi those devices launch, it will be time to handicap the marketplace. Which console will succeed? Which console will fail? And perhaps most importantly, which console will win the next-generation battle?[Image credit: Andreas Levers]

I’m sure there are those in each company’s camp armed with reasons their particular favorite will win.

Those who support Nintendo will say that the company’s commitment to innovation and fun, coupled with its high-quality first-party library, will be enough for the Wii U to dominate the gaming market.

Sony fans disagree. They point to the PlayStation 3’s late surge in the gaming space to make their case. Sony fans believe that the PlayStation 4 will come with high-quality specs and a large game library that will give it the edge. To think otherwise, they might say, would be nonsense.

Microsoft, however, has a different take. The Xbox 360 has proven steady over the last six years, and it’s likely that in the U.S. and Western Europe, it will have a strong showing. And Microsoft’s fans say that the software giant’s online experience and Kinect functionality will impress gamers and get enough people to join up to take over the console market.

I honestly believe that all three companies have a chance at dominating the next-generation console market. After all, coming off the GameCube, no one thought that Nintendo would win the space, but it did so with the Wii. And although the PlayStation 3 got off to a slow start, it’s starting to show now why it had so much promise in the beginning.

[aquote]I don’t know how Nintendo expects to hang tough in the long term[/aquote]

At this point, though, I don’t quite know how Nintendo expects to hang tough over the long-term. The Wii U, while nice for its fans, will be trumped very quickly by whatever Microsoft and Sony offer. And if Nintendo doesn’t find a way to respond with some sort of update or new addition to the console’s featureset, it will be impossible for the game maker to keep pace.

Sony’s issue might have something to do with cost. The company has historically tried to deliver a high-end product, but in the gaming market lately, value has been the name of the game. And I’m not sure Sony realizes that.

Microsoft, meanwhile, might be popular in the U.S. and Europe, but the company has yet to establish itself in Asia. And until it capitalizes on that extremely important continent, the Xbox 720 will have some trouble.

So, while all three consoles might have some features that could push it over the top, they all also have some troubles. And the winner of the next console generation will be determined not by how much “stuff” they all have, but by how well they can get over the issues and capitalize on their virtues.

It should be a fun fight to watch.
