Hello everyone, I hope you are all doing well. Today we will be changing the Windows Lock Screen background. Changing the lock screen background is a very easy task and it can be done in a very short time. So let's jump right into it.
The first thing you need to do is to press the Windows start button on the bottom left and then press settings.
Once the settings screen appears, choose and click on Personalization.
Inside personalization, click on the Lock Screen tab.
On the right screen, under the picture, you will find Windows spotlight, click on it to bring a drop-down menu up.
Your choice is presented as a single picture for background or slideshow, a series of pictures that are going to be looped in a given time interval.
If you would like just a single picture for your background, choose that and click on it.
Once you are in choose picture dialog, click on the browse button and navigate to the picture on your storage which you would like to have as a background.
If however, you fancy slideshow as your lock screen background, click on the background drop-down menu and choose the slideshow. Next, click on add a folder and navigate to a folder where you have pictures that you would like to have as a slideshow for your Windows lock screen.


Error CausesThe number of Hertz is the number of how many images your screen draws in one second. So monitor with a refresh rate of 60Hz will draw 60 images each second on your screen. To most users, this will look fine and enough but actually, if you would place them in front of a 120Hz screen difference will be visible right away.

In most simple words just looking at a screen that has a higher refresh rate will produce a more natural feel of things, although some people would argue that flickering can not be seen on 60Hz monitors and that should be enough, I would argue that they never watched the movie, played the game or used high refresh rate screen when they can state something like that.
Yes, 60Hz might be enough to look at the web page or read some documents but long exposure to 60Hz can have a tiring effect on the eyes in the long run. 120Hz and above just feel more relaxed and it is far less demanding on the eyes. Watching movies also is much better on a higher refresh screen, with way much less motion blur in fast scenes giving the overall experience a greater natural feel.
Gaming is perhaps an area where a refresh rate of 120Hz and above will show its best. Having a higher refresh rate will be easier on your eyes and can even give you a competitive edge. When for example you have twice more images per second on your screen than your opponent his movement will be more fluid and predictable because of that and overall precision will be much higher when moving the cursor in the game since more frames per second means more precision and smoother movement.
After all the positive things that were said about the advantages of high refresh rates, it is just fair to look at some negatives or in this case only negative one and that is Computer power. As said in the previous section having a 120Hz refresh rate means having 120 frames displayed on the screen per single second. Having even higher monitors like 360Hz means even more frames per second and in order to actually see all of that frames you will need to have enough computer power to back it up. Having for example screen with a refresh rate of 240Hz means nothing if your GPU and rest of the computer are able only to push 150 frames per second, in this case, you will still have 150 frames in one second despite the monitor being able to go to 240.
Generally and with all of my heart I would recommend moving away from 60Hz monitors, yes they are cheaper and more affordable but at the end of the day if you are someone like me who spends most of his daily time in front of the computer you would be grateful to have higher refresh rate screen and save your eyes, and after all, why not enjoy some smoother and better movie and game experience as well as saving your eyesight.

This is a fairly common error, especially for people who own more than one computer upon which Windows 10 is installed and activated. The gist of this error code is that the product key that you have entered has already been claimed or used on a different computer. Because there are limitations on the number of computers that can use any given license activation code or product key, this error code can arise when you have exceeded that limit. If you have a single-use license and have already entered the particular product key onto another machine, you may see this error come up during activation.
Both Error Code 0xC004C770 and Error Code 0x803FA071 arise from the same problem and the same steps can be used to resolve both error codes.
Error CausesError Code 0xC004C770 is likely to appear on your screen during activation of Windows 10 if you or anyone else in your organization have already entered in the product key used on another computer. If you have a multiple-use license, the product key that you are entering may already have been used for the maximum number of computers allowed under that license.
There are two basic methods for addressing the issues associated with Error Code 0xC004C770. These methods can easily be implemented by anyone who is comfortable interacting with the Windows Store from their computer, which makes the resolution of this particular error code fairly simple and straightforward.

You can also get in touch with the Windows technical support team to assist you in the process if needed.
If you have already used the product key on another computer or have used it on the maximum number of allowed devices, you may need to purchase an additional product key for the computer with Error Code 0xC004C770. Product keys can be purchased physically from a retailer that sells Windows 10 software licenses or purchased directly from the Windows store.
To purchase a new product key directly from the Windows Store, follow the steps below:
If you are unable to see the “Go to Store” option when you reach the “Activation” page, you may not be set as an administrator of your machine. In this case, get in touch with the support personnel from your company to complete the purchase, installation, and activation process on your computer.
For users who have changed out parts of their computer’s hardware, like putting in a new motherboard or activating a new hard drive, you may have more success if you attempt activation through a phone.
