As you know, Microsoft constantly releases new updates with the main goal of fixing bugs as well as deliver users with new and exciting features. However, there are times when the latest update comes with an unwanted bug. One of these bugs is an error message saying, “Low Disk Space. You are running out of disk space on Local Disk (G:). Click here to see if you can free space on this drive.” So if you have recently installed a Windows 10 update, then you’ll most likely see a completely new drive on your computer which will appear right after the installation of the update and you’ll also start seeing the aforementioned error message. It gets irritating as this error message keeps on popping up even if you still have a lot of free space on your other drivers. Obviously, the main reason why this error message pops up all the time is the bug brought along by the Windows Update. This bug unhides the recovery partition drive and allocates it a drive letter which is why you are seeing a new drive in your computer. Thus, you can get rid of the pesky error message by simply removing the letter of the new drive. Just remember that you must not delete anything from the recovery partition drive nor format the drive. Formatting or deleting the recovery partition drive can heavily affect the recovery of Windows since the data on the drive is used by the Windows Recovery Environment or your system’s manufacturer. A lot of users have reported that removing the drive letter has resolved the issue. And if you worry that removing the drive letter will delete the drive, you are mistaken. This solution is basically harmless and is proven effective to make the notifications go away. Carefully follow the instructions below to get rid of the Low Disk Space notification by removing the drive letter.

• Step 1: Tap the Windows key once.
• Step 2: Next. In the Windows Start Search, type in “command prompt” and right-click on Command Prompt from the search results and select the “Run as administrator” option or you could simply tap Win + R keys and then input “cmd” and hit Enter to open Command Prompt.
• Step 3: After opening Command Prompt, type in “diskpart” and tap Enter.
• Step 4: Next, type in “list volume” and tap Enter. After that, you will see a list of drives.
• Step 5: Take note of the letter associated with the newly created drive.
• Step 6: Afterwards, type in “select volume <drive letter>” and tap Enter. Take note that you must replace the <drive letter> with the drive letter you’ve found in Step 5.
• Step 7: Now type in “remove letter=<drive letter>” and then tap Enter. Once again, replace the <drive letter> with the letter you took note of in Step 5.

Finally upgraded to Microsoft’s newest OS, but the performance is a bit sluggish? Here are a few useful tips you may not have thought about that could significantly transform your experience!

How to speed up Windows 11?

1. Disable startup programs

There are many programs that launch right on startup that really aren’t essential. This, in turn, causes your PC to launch and run more slowly.

To check which programs are enabled on startup, go into the Task Manager and select the Startup tab. Find every program that doesn’t need to launch immediately, right-click on it and press ‘Disable’.

This will not shut down the program in that instant. It’ll just prevent it from running automatically as you turn on your PC. You can always launch it manually when you need it.

2. Expand your memory and storage

If you want your PC to run super smoothly, you need to have enough memory to support that. This is especially significant for those of you who love to multitask. Upgrading your RAM gives your PC more space to store the temporary data it needs to complete processing tasks. In other words, processing takes a lot less time.

Your long-term storage is equally important. Hopefully at this point you’re already using SSD over HDD, since this type of storage offers a faster boot time.

In any case, we recommend expanding your storage capacity. The more files and data you store, the more there is to load, significantly influencing your PC’s speed. Larger storage capacity means new data and essential updates can be stored comfortably, preventing any strain on your PC’s performance.

3. Clean up disk space

If you aren’t willing to upgrade your storage just yet, the least you can do is clean up your storage right now. 

Aside from manually deleting stuff you no longer need, you can also get rid of temporary files that clutter up your storage and eat up performance for no reason. To get to them, click Windows + X and select ‘Run’ (or just type it in the search bar).

A small window will pop up, where you need to type %temp%. This will take you to a whole folder full of all the temporary files you can remove without thinking twice. 

For those who upgraded from Windows 10, there’s a neat trick to get rid of potential leftover files you don’t need on your brand new iteration. Only do this if you’re 100% sticking with Windows 11, though. Go to System > Storage > Temporary files. Make sure to only leave ‘Previous Windows Installation’ and ‘Windows Update Clean-up’ checked and click on ‘Remove files’.

Lastly, make use of Windows 11’s fantastic Storage Sense feature. Turning it on will enable your PC to constantly watch out for junk or unused files to optimize your PC’s performance to the maximum.

4. Install pending updates

This one should go without saying, but pending updates can be detrimental to your Windows 11 performance. The longer you leave them untouched, the more bugs the outdated programs and patches can cause. So, make sure to regularly check for updates and install them as soon as they’re available.

5. Disable visual effects

As cool as visual effects, animations, shadows and transparency are, they can also put quite a toll on your computer’s speed. On a newer setup this generally shouldn’t be a problem, but if you do notice a drop in performance, definitely consider turning off some of these settings.

To do this you can go to the Control Panel, System Properties and click the ‘Advanced’ tab. In the Performance section, choose Settings. If you’d like a quicker way to get to the dialog (Performance Options) with Visual Effects, you can also type sysdm.cpl in the search bar.

Once there, you can either have your PC choose what’s best, choose the best appearance or the best performance. The other option is to manually toggle the effects off and on. The biggest obstacles to speed are taskbar animations, window shadows, control/element animations and animations upon minimizing/maximizing.

In the same vein, you should go to Settings > Personalization > Colors and disable Transparency, to prevent your computer from doing overtime just to hit the aesthetic appeal.

6. Get rid of bloatware

Bloatware is one of the biggest culprits of slow computer speed. 

Pre-installed software that’s pretty much useless but takes up valuable system resources has been around since day one. No matter which device or platform you’re talking about. Luckily, a lot of it is removable, making it easy to lighten the load on your device.

To boost your Windows 11 computer, go to Settings > Apps > Installed apps. You’ll probably see a bunch of apps you don’t want or need. Click on the three dots next to each one you want to remove and press ‘Uninstall’. 

Aside from helping optimize performance, removing bloatware has another great benefit. Unfortunately, often this pre-installed software is quite vulnerable, exposing you to great risk of cyberattacks. So, removing it definitely improves your device’s security and gives you at least some peace of mind.

Summary

These are a few of our fastest tips for boosting performance. There are other, more complex and time-consuming ways, of course. If you’ve tried these quick ones and still need advice on how to improve your PC’s speed, feel free to reach out!

Default Taskbar inside Windows 11 is pretty good if we are talking about its height. Sitting at 48 pixels it is a pretty decent size considering functionality and size ratio but if you want to make it a little larger or smaller know that you can do that as well in order to customize it for your personal needs. Sadly in order to actually change height size, you will have to do it inside the registry editor, but worry not, we are here with you to guide you all the way, one step at a time. Also, note that you can only change Taskbar from normal size of 48px to either small of 32px or large gapping at 72px. Icons will also be scaled proportionally with the taskbar.

Guide

1. Press ⊞ WINDOWS + R to open the run dialog
2. Inside run dialog type in RegEdit and press ENTER
3. In registry editor locate and find HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced
4. Right Click on it to select it and create a new DWORD (32-bit) value
5. Name the value TaskbarSi
6. Inside TaskbarSi double click in order to set the value to 0 if you want a small size Taskbar, 1 is if you want to revert back to medium (standard one), or type in 2 if you want a large Taskbar.
7. Save and close the Registry editor
8. Reboot PC

And there you go, you have successfully changed Taskbar size inside Windows 11. If you want to revert back to standard size just repeat steps and place 1 as a value in point 6.

Today most people have Facebook accounts where they keep in touch with friends and family. But large Facebook network of users is also very interesting to another party as well, hackers. There are many ways hackers can steal your data via direct hacks, trickery, and social engineering in order to get your credentials, emails, and many other things using them to wreak further havoc. Once a hacker has needed information it is very difficult to minimize impact and all of your information could be compromised from a list of friends to credit card numbers. Keep on reading to learn how can you protect yourself against these attacks and learn about common practices that hackers use in order to steal your data.

Stealing Facebook data via email

A couple of years ago there was a lot of talk about not opening suspicious emails. Well, it still holds today. The difference is that today’s fake emails have become very difficult to differentiate from official ones since hackers put the effort into creating them copying fonts and layout, making them identical to original ones. So if emails look and feel like original ones how do you know if it is fake? Very simple, you do not click anything in it. If Facebook or for that matter any company wants to contact you they will do via their platform. Clicking inside a hacker's email will lead you probably to a fake Facebook website replica where you will have to type in your username and password providing an attacker with your login credentials, etc. If you receive this kind of mail where there are threats about terminating an account, missing payments, etc. it is always the best thing to go directly to Facebook and see if you have any kind of notifications there. Do not trust any emails that ask for account information, request money, or threaten to suspend your account.

Phishing attacks

As stated previously if you click on the link inside fake mail it will probably lead you to a website replica of the original. Although hackers can pretty much copy all things from an original website like layout, fonts, colors, etc. There is one thing that he cannot, web address. Take a good look into your browser address bar to see if there is a typo or anything strange in the address of a website. Also, make sure to check for the secure icon in the web address before signing in.

Fake Facebook buttons

If by any chance and for whatever reason, you end up on a fake Facebook site be vary careful about like and other buttons since buttons themselves behave and act like links inside your browser. IF when you click on like you get a prompt to sign in, it is almost 100% that you ended up on a phishing fake website.

Password brute force attack

Having complex and long passwords is a must. If your Facebook password is 12345 there is a very high chance that if a hacker wants he can easily guess it via trying out the most used and simple passwords via simple guessing. To avoid being hacked just for having poor passwords try to think of something longer, combine letters and numerical characters, place special characters inside it or just simply as the best solution use a password manager and create passwords with it.

Password grab outside Facebook

If you use the same password for multiple accounts which is a big no-no and you should not do it then hackers can use passwords from other services and login into your Facebook in order to steal data. Avoid these situations by having different passwords for different accounts or use a password manager to keep everything in order.

Hacking via key logger

Some time ago we have made an article which explained in detail everything you need to know about key loggers here: https://errortools.com/windows/how-to-know-if-you-have-keylogger-in-windows/ Anyway, this is a more advanced hacking technique in order for hackers to steal your data and it includes placing malicious applications into your system that records your keystrokes and sends them directly to hackers. Since this is an application best protection against this type of attack is to have a security suite installed and active on your PC or device you use to go to Facebook.

Connecting and surfing on an unsecured network

Using no password and unsecured WI FI or any other type of network is risky at least. You can have all protection installed on your device and have a strong password but hackers also logged in to the same network can track all outgoing stuff going through mentioned network leaving you again exposed to attacks. It is better to connect to your mobile operator network than on free WI FI, at least there is some level of security in your operator network while free WI FI is completely unsecured. Getting a virtual private network or VPN is also one thing you could think about for protection since almost all VPN services will encrypt your data thus providing you with a security layer even on unsecured Wi-FI.

Conclusion

Hacking and stealing have come a long way from their infant stages and in today’s world when we use a lot of gadgets and have plenty of online presence taking some steps for security is a must. I hope that you have found anything here informational and helpful so you can avoid getting your data compromised.

The Google Chrome browser checks the SSL Security Certificate of the website that you are trying to open. However, if Chrome is not able to check the certificate then you might encounter an error related to the SSL Certificates which you might face when browsing the web. This particular error is the ERR BAD SSL CLIENT AUTH CERT error which is caused by many factors such as the computer’s Time, Cached Data is corrupt, Date is out of sync, as well as third party software installed in your computer is the one that’s blocking the site and many more. The ERR_BAD_SSL_CLIENT_AUTH_CERT error might also be coming from the website’s end. It could be that the server is rejecting the certificate the client website is sending. The certificate might have already expired or the server may not trust its issuer – whichever the case may be, here are some options you can check out to fix the error.

Option 1 – Sync Date and Time

The first thing you can try is to sync the Date and Time of your computer as the wrong Date and Time settings are one of the most common causes of connection problems like the ERR_BAD_SSL_CLIENT_AUTH_CERT error. This is because of the incompatibility between the SSL Certificate validation date and the System Clock. Thus, you have to sync your System Clock. Refer to the steps below to do so.

• Right-click on the Taskbar and click on the Adjust Date and Time option.
• Next, click on the Sync Now button to synchronize the Date and Time with the Microsoft Servers.
• Now make sure that the Time Zone that’s set on the same page is correct.

This might be a very basic solution but oftentimes it works in fixing this kind of error in Google Chrome. Follow the steps below to clear the data in your browser.

• Open your Google Chrome browser.
• After that, tap the Ctrl + H keys. Doing so will open a new panel that allows you to delete the browsing history and other data in your browser.
• Now select every checkbox that you see and click on the Clear browsing data button.
• Then restart your Chrome browser and check if you can now open any website or not.

Option 3 – Try to check and fix any possible conflicts with third-party programs

Third-party programs like internet protection software could be interrupting the connection and causing the error. For some unknown reason, your antivirus program or firewall might be detecting the webpage you are trying to open as malicious or with less credibility which is why it is blocking the browser from opening the website. To fix that, if you have third-party programs installed like VPN, security software, or any add-on, or firewall, you can disable them temporarily and see if it fixes the problem and you’re able to pull up the website. After a while, you have to enable them back and configure their settings so that the website won’t get blocked again.

Option 4 – Try enabling SSL 3 / TLS and disable QUIC Protocol

If you were using Google Chrome when you got the ERR_BAD_SSL_CLIENT_AUTH_CERT error, then you need to follow the protocol fixes for SSL3/TLS and QUIC which are usually some of the reasons that cause the SSL version / Cipher Mismatch. It also has a few fixes for Windows 10 computer where you can clear the certificates and make sure that your computer date and time is in sync with your time zone and so on. If you were using Edge or Internet Explorer when you got the error, then you have to follow the steps below.

• Type “Internet” in the search box of your browser. After that, you should see the Internet Options from the search results.
• Next, open the Internet Properties window and switch to the Advanced tab and then scroll down to the Security section.
• From there, check the “Use TLS 1.1” checkbox as well as the “Use TLS 1.2” checkbox and then click OK to save the changes made.

• Open Firefox and in the address bar, type “about:config” and hit Enter.
• If a warning appears, just click on the “I accept the risk!” button to proceed.
• Next, type in “TLS” in the search field and hit Enter.
• Then look for “security.tls.version.min” and double click on it and set its integer value to 3 to force the protocol of TLS 1.3.
• Now click OK and restart Firefox and do the same thing with SSL.

Option 5 – Try to update Google Chrome

You might also want to try updating your browser to its latest version and have it installed in your computer. After you install the update, check if you can now open the website you were trying to open earlier.

Option 6 – Get rid of any conflicting browser extensions

• Open Chrome and press Alt + F keys.
• Go to More tools and click Extensions to look for any suspicious browser extensions or toolbars.
• Click the Recycle bin and select Remove.
• Restart Chrome and press Alt + F keys again.
• Proceed to On Startup and mark Open a specific page or set of pages.
