How to Fix Error 421

1. Check Speakers or/and Headphones first

   The first thing would in any troubleshooting be to check are your speakers turned on or are your headphones connected and the volume or switch on them is set properly. Nothing more embarrassing than spending an hour or so troubleshooting only to find out that issue was in a malfunction of speakers or them not being turned on.

2. Check the Volume control in Windows

   Same as the previous step where you have checked hardware, now it is time to check to see if the volume control is set properly and not by any chance muted or volume is brought all the way down.

3. Check if the Device Manager is reporting an error and update the driver

   If both hardware is functioning properly and volume control in Windows is set correctly then the issue might be in Windows not detecting device or driver malfunction. In any case, the Device Manager will be the one who will report this problem. In order to check to see if the driver is properly working press ⊞ WINDOWS + X to open the hidden start menu. Once it opens, click on Device Manager to open it, If you have a driver device error inside Windows, you should see it immediately when entering the Device Manager, it will have a yellow exclamation mark beside it. Right-click on it and choose update driver.

4. Reinstall driver

   If driver update failed or you already have the latest drivers, reinstalling them could fix the issue since drivers might have corrupted during installation of some update or application. Follow steps from point 3 to get to the driver in Device Manager, then right-click on it but instead of update choose to uninstall. Reboot Windows once the driver is uninstalled and Windows will install a new one.

5. Check Windows update

   Check to see if the latest Windows update is installed, update your Windows if needed

6. Fix driver issue with DRIVERFIX

   If everything else fails, get DRIVERFIX, a premium solution for your PC issues, and fix driver errors.

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:

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.

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.

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.

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.

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.

A surprisingly large amount of things present at your home can and do interfere with your wi-fi signal making it weak so devices are dropping it, having trouble connecting, or being slow.

Hello and welcome to our latest article where we will take a look at all things that are present in a lot of homes but are very bad for your WI-Fi signal.

Bad router placement

Having a router in a bad position can have some really large effects on WI-Fi signal strength and its availability. Usually, we do not give great attention to where we are placing our router but it has been proved over and over again that being close to certain objects does indeed have a great influence on the wireless signal strength and performance.

So, what are these objects and bad positions where we could place the router and effectively kill his Wi-Fi capabilities?

Fish Tanks

Water will block all radio waves including Wi-FI signals and waves themselves, so having a router next to the aquarium or any large source of water is a bad idea. You should always look at water as something bad for your Wi-Fi and move your router away from it as far as possible.

Bookshelves

Paper is another story and example of the dampening effect on radio waves. Did you know that various patterns of paper are used in silent rooms and recording studios in order to eliminate sound reflection from surfaces? Well besides absorbing sound waves, the paper also absorbs Wi-Fi signals and if you have a large bookshelf with a lot of books packed one beside another you just have a great wall of signal absorbing.

Mirrors

The problem with mirrors is in their coating that goes over the glass in order to turn it into the mirror, that coating is metal and as such, it is absorbing signals in large amounts. If you have an old or high-quality mirror that has a silver coating things are even worse since silver will absorb even more waves than modern cheap ones.

TV

Yup, TV is also on this list and for a similar reason as a mirror, although TV does not have coatings of metal, they have something even worse: a large metal plating on the back. Metal plating is there to produce structural integrity of the TV set and provide it with shielding from electromagnetic waves and as such it will prevent Wi-Fi waves as well. Do not place the router behind your TV.

Things that influence signals in homes

Any kind of metal decoration

Now when we covered mirrors and TV because of the metal they have, we must take a look at the metal itself. Any kind of metal stuff that you might have like baskets, figures, statues, frames, etc will effectively block your signal.

Kitchen appliances and Home utilities

Kitchen appliances like refrigerators, microwaves, ovens, stoves, etc. along with home appliances and utilities like dishwashers, washing machines, dryers, etc are large metal objects enclosed in a metal cage that will block signals from spreading further and it is no secret that most kitchens have weaker Wi-Fi because of this reason.

Home gyms

This is a logical conclusion as to everything explained so far if you have a workout room or small gym at home it is probably filled with weights that are metal and have mirrors inside, all of that will interfere and block signals.

Things blocking your Wi-Fi that you have no easy control over

Walls

Thick walls will dampen signals, thick walls from bricks will dampen even more and concrete walls will kill it almost completely. Any kind of metal reinforcement wiring inside walls will reduce and kill signals as well.

Floors and ceiling

This is somewhat important if you have a floor beneath or under the room where is your router located, but for the same reason how walls are blocking your signal floor and ceiling can do it as well, especially since most of the time they are made of some stronger material like concrete with metal fence inside.

Heating systems

If you have a heating system that is composed of metal radiators with water inside, then in terms of Wi-Fi signal strength you have an aquarium but in a metal box, and as such it will greatly reduce signal strength.
