We couldn’t update system reserved partition” - What is it?

Customers will most likely encounter the “We couldn’t update system reserved partition” error when upgrading to Windows 10 from Windows 7 or Windows 8.1. This error may also come with error code 0xc1900104 or error code 0x800f0922.

Solution

Error Cause

“We couldn’t update system reserved partition” Windows 10 upgrade error is normally caused by too little space on the System Reserved Partition (SRP). The System Reserve Partition is an additional small partition created by Windows, which stores boot files. The SRP can be filled up with security apps and third-party anti-virus. Once this partition has insufficient space, the system will not be able to upgrade to Windows 10.

Further Information and Manual Repair

Caution: The following steps are complex and need to be done by experienced users especially using the command line. Once an error is made in entering commands, there’s a chance that your device can be put in a no-boot situation, or data stored on the device can possibly get lost.

To upgrade to Windows 10, your device needs to have at least 15MB free space on the System Reserved Partition. Follow the procedure below and then try upgrading again.

First, know if the System Reserved Partition is whether in GPT or MBR partition style:

1. Open the Run window by pressing the Windows key + R. Type msc in the window then press Enter.
2. Right-click on the Disk where SRP is located then select
3. Click over the Volumes
4. On the Partition Style line, you’ll see which partition style your device is using, either Master Boot Record (MBR) or GUID Partition Table (GPT)

Second, determine which method you will need:

Depending on what partition style your device has and whether you’re currently on Windows 7 or Windows 8/8.1, there are various methods you need to do.

Method 1: Windows 7 or 8/8.1 with GPT partition

1. Click on the Start button and search for cmd. In the results, right-click on Command Prompt then choose Run as administrator. The command prompt window will appear.
2. Type mountvol y: /s at the command prompt then press Enter. This command will add the Y: drive letter where you can access the System Partition.
3. Type taskkill /im explorer.exe /f then hit Enter. Afterward, restart explorer in Admin mode by typing exe and hitting Enter.

NOTE: While in Admin mode, some apps like OneNote will not run.

4. Open File Explorer then type Y:EFIMicrosoftBoot in the address bar. Hit Enter.
5. Choose the language folders you want to permanently delete. Language folders are named with four letters split with a hyphen. For instance, you want to delete the German language: choose de-DE.
6. Optional: You can also delete unused font files for more space. Type Y:EFIMicrosoftBootFonts in the address bar then press enter.
7. Once you permanently deleted the unnecessary files, reboot the device to return to explorer.exe to normal mode and remove the Y: drive letter.

Method 2: Windows 7 with MBR partition

Doing this method will make a permanent, but small increase in the free space of the device’s SRP.

1. Delete language folders

a. Open the Run window by pressing the Windows key + R. Type diskmgmt.msc then hit Enter. b. Select System Reserve partition then right-click on it.

c. Choose Change Drive Letter and Paths then select Add.

d. Type Y for the drive letter then click OK.

e. Click on the Start button and search for cmd. In the results, right-click on Command Prompt then choose Run as administrator. The command prompt window will appear.

f. Type Y: at the command prompt then press Enter.

g. Once you’ve switched to drive Y, type takeown /d y /r /f . then hit Enter.

NOTE: Ensure that the space and period after “f” is included in order for the command to work properly      

h. Type icacls Y:* /save %systemdrive%NTFSp.txt /c /t then hit Enter to back up the permission to the drive.

NOTE: Ensure that all files are marked as successful and that no files are marked as failed.

i. Type whoami then hit Enter. Record the username that appears. Afterwards, type icacls . /grant <username you got from whoami>:F /t then press Enter.

NOTE: Ensure that there’s no space between the username and “:F” or the command will not work.

j. In the File Explorer, open the SRP drive and select the Boot folder. Choose the             language folders you want to permanently delete. Language folders are named      with four letters split with a hyphen. For example: de-DE is the German language          while en-US is the U.S. English language.

2. Truncate the NTFS Log:

a. Open the Command Prompt then type chkdsk /L Y: to check the size of the NTFS Log. If the NTFS Log size is less than 5000KB, you need not truncate the file.

b. Type chkdsk /L:5000 /X /F then hit Enter to truncate the NTFS Log.

c. Return to Disk Management window. Select Action menu then select Check if the device’s SRP now has a larger amount of free space. Once there’s enough space, right click the System Reserve Partition then select Change Drive Letter and Paths. Choose Y: then select Remove.

3. If there’s still not enough available space after truncating the NTFS Log, resize the USN journal:

a. Open the command prompt then type fsutil usn queryjournal Y: to display the size in hex value. Convert the hex value to decimal then divide it by 1048576. The result you will get will be in MB. If the journal size is 30MB or more, proceed with truncating the file.

NOTE: To convert the Hex value to Decimal, open the Calculator app in Windows then choose View menu. Select Programmer then choose Hex. Type the Hex value then choose Dec.

b. Type fsutil usn deletejournal /D /N Y: then hit Enter to delete the journal. Type fsutil usn createjournal m=1500 a=1 Y: to recreate the journal having the new log size value.

4. Restore permissions

a. Type icacls Y: /restore %systemdrive%NTFSp.txt /c /t in the Command Prompt. Check if the files were successfully processed before proceeding. If you see a message saying some files failed while processing, this is normal since some of the files have already been deleted before performing a backup. However, if there are no successful files indicated, the command was not properly executed.

b. Type icacls . /grant system:f /t then hit Enter to adjust the ACL back to System. Now, you can set the owner of the drive by typing icacls Y: /setowner “SYSTEM” /t /c then press Enter.

c. Check if the device’s SRP now has enough free space by going back to Disk Management and refreshing the data. If the SRP already has sufficient space, you can now remove the drive letter. Right-click on the System Reserved Partition then choose Change Drive Letter and Paths. Select the Y: drive then choose Confirm deleting the drive letter by clicking OK.

Method 3: Windows 8/8.1 with MBR partition

This method makes a larger, but temporary, increase in the SRP free space.

1. Be sure you have an external drive having at least 250 MB free space and formatted as NFTS.

2. Open Run by pressing the Windows key + R. Type mscthen to choose the Recovery Partition. Right-click on it then choose Change Drive Letter and Paths.

3. Select Add then type Y for the drive letter, click

4. Click on the Start screen then type cmd in the search bar. In the results, right-click on Command Prompt then choose Run as administrator. The command prompt window will appear.

5. Switch to another drive by typing Y: in the command prompt. Once you’re in the drive Y, type takeown /d y /r /f .

NOTE: Ensure that space and period after “f” are included in order for the command to work properly.

6. Type whoami then hit Enter. Record the username that appears. Afterward, type icacls . /grant <username you got from whoami>:F /t then press Enter.

NOTE: Ensure that there’s no space between the username and “:F” or else the command will not work.

7. Once the command is completed, type attrib -s -r –h Y:RecoveryWindowsREwinre.wim then hit Enter.
8. Open File Explorer and check the drive letter of the external drive you’re using (In this case, let’s assume F: is the drive letter of the external drive so when you see F: for the rest of the steps, this means the drive letter of the external drive you’re using).
9. Type mkdir F:RecoveryWindowsRE in the Command Prompt then hit Enter. Afterward, type xcopy Y:RecoveryWindowsREwinre.wim F:RecoveryWindowsREwinre.wim /h
10. Type C:WindowsSystem32Reagentc /SetREImage /Path F:RecoveryWindowsRE /Target C:Windows to map the new path
11. Verify if the copy was successfully done then type del Y:RecoveryWindowsREwinre.wim /F
12. Return to Disk Management window. Click on the Action menu then hit Check if the device’s SRP now has a larger amount of available space. Once there’s enough space, you can proceed with the upgrade.
13. Upon completion of the upgrade, move back the wim file to the Recovery Partition. At this point, you can re-map now the location by:
    1. Open the Command Prompt then type xcopy F:RecoveryWindowsREwinre.wim Y:RecoveryWindowsREwinre.wim /h and press Enter.
    2. Type C:WindowsSystem32Reagentc /SetREImage /Path Y:RecoveryWindowsRE /Target C:Windows to re-map to the original path.
14. Return to the Disk Management window. Right-click on the Recovery Partition then choose Change Drive Letter and Paths. Select the Y: drive then choose Remove.

Valve has officially announced that Steam Deck will be compatible with Windows 11 despite TPM 2.0 Microsoft requirements. From the beginning, Deck was announced like a mini handheld PC device. Powered with new Steam OS 3.0 based on Linux. However, besides out-of-the-box OS it was also stated that Deck will be a personal device meaning that other PC-based operating systems could be installed on it and even run your typical applications in it. Since Microsoft announced Windows 11 hardware requirements, specifically the TPM 2.0 requirement many users voiced concern that Steam Deck will not be able to connect to Windows 11 TPM 2.0 is something that Microsoft requires for every internal and hardware component that is to connect on a Windows 11 device. This is to ensure that only trusted devices would be included in the array of a PC setup and avoid any problems like malicious hardware injecting software into a system. This would also minimize the compromise Windows would have, as unverified or untrusted devices connect to a Windows PC. However, Valve and AMD are ensuring us that Deck will not have any issue connecting to a PC running Windows 11 or even if you wish to transform Deck itself into a Device running Windows 11.

If you are trying to copy large files that are over 4GB to a USB flash drive or SD card, but you suddenly get an error message saying, “File Too Large, The file is too large for the destination file system”, read on as this post will help you fix this problem. A user recently reported that while trying to copy a 4.8GB zipped file from a Windows 10 PC to a new 8GB USB drive but only got the File Too Large error message instead. If you share the same problem with this user and you know that there is more than enough available space for the file in your USB drive or SD card, continue reading until you get to the instructions provided in this post so that you will be able to copy the file successfully. It is most likely that the USB drive has been FAT32 formatted which is why you’re unable to copy the file and got an error. The FAT32 file system has a built-in limitation on the size of the individual file that it may contain. For instance, it’s 4GB so even though collectively, it may have files or even 1TB individually it shouldn’t be more than 4GB. Thus, you need to change the file system from FAT32 to NTFS. To do that, carefully follow the instructions provided below.

• Step 1: Connect the USB drive and open the Windows File Explorer.
• Step 2: Afterwards, right-click on the USB drive letter and select Format from the context menu.
• Step 3: Next, select NTFS instead of FAT32 the instant a dialog box appears from the drop-down menu for the file system.
• Step 4: Now click on the Quick Format option and then click the Start button to reformat the USB drive.

Note: There is also another way you can change the file system. In this alternative way, you need to open an elevated Command Prompt and type the convert X: /fs:ntfs /nosecurity command, and hit Enter to execute it. Remember that in this command, “X” is the letter of your USB drive so whatever the letter of your drive is, you need to make sure to put it instead of “X”. Once the process is completed, try copying the file again.

Every computer has to have a graphic card, it is one of the essential components in order for the computer to work.

The GPU’s manufacturer and model names are displayed at the top right corner of the window. You’ll also see other information, such as the amount of dedicated memory on your GPU, in this window. Windows 10’s Task Manager displays your GPU usage here, and you can also view GPU usage by application. If your system has multiple GPUs, you’ll also see “GPU 1” and so on here. Each represents a different physical GPU.

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.

Privacy is a hot topic lately in all circles so naturally themes like private or incognito browsing pop up immediately as discussion topics. Naturally, when discussing private or incognito browsing it is very important to understand what exactly private or incognito browsing is, what does it do and how it works in order to shed some light on is it really private and safe as we are told. So, when you browse the internet normally websites have tendencies to save your browsing data, save cookies, remember passwords, etc in order to provide you with a better surfing experience next time you visit that same site. Private or incognito browsing treats you as a completely new user which is the first time visiting a given website. It clears all your data, including your browsing history, cookies, etc., on exiting. Every website you visit in private or incognito mode treats you as a new visitor, even if you have visited it before in incognito mode. And basically, that's it. So is it really private? No, it is just a non-remembering mode of internet browsing where after your browsing session history and other data is cleared from the browser, but while you are on the internet you are pretty visible to all like any other normal user. There are a lot of misconceptions and wrong thinking about browsing the internet in this mode so let's take a look at some typical ones.

1. The government and other companies can not track me

   Many people think that the Government cannot trace their identity when they surf privately. This is only a myth. There are many ways by which the Government can reach you if you do something illegal. When you surf online, you are connected with an ISP of your area, which helps the officials track your location.

2. Virus and other malware can not infect me while in private or incognito mode

   Many people think that private mode protects them from virus and malware attacks. It is not true because malware and viruses can enter your PC through a software download, phishing email, etc. To protect your PC from virus and malware attacks, you should have good security software.

3. My IP address is hidden when I am in incognito or private browsing mode

   This is not 100% true. If you search “What is my IP” in incognito and standard mode, you will get the same results. This means that websites can view your IP address in private mode also. Using a VPN would be a good option if you want to hide your IP.

4. I can not be tracked via ads

   Since cookies are deleted after exiting private browsing, many people think that ads cannot track them. When you surf in incognito mode, the browser saves cookies in a temporary mode, allowing ads to track you during your entire private browsing session.

5. I am not visible when I am in incognito or private

   You may think if you sign in to your Gmail or other social media accounts in private mode, no one will see you online. This is not true. It does not matter whether you have signed into your account in normal mode or incognito mode; others can always spot you online.

In your regular browsing mode, you may have some addons, extensions, themes, etc installed and you can use them. They may track your activities. The data is deleted when you exit the browser. When you use the private browsing mode, the browser is loaded in its original form, typically without the installed addons, extension, themes, etc. The data gets deleted when you exit the browser. This mode doesn’t save data to disk but keeps it in memory during the current session. If you are really concerned about your privacy we have articles about using DuckDuckGo and deep web where you can be sure that your browsing sessions are encrypted.
