How to Remove Your Mobile Number From Truecaller

December 17, 2020

Do you know how you can remove your number from Truecaller’s database? There is no direct way available to delete the account from the app; however, it is possible to do so by deactivating your Truecaller account, followed by delisting the number.

Truecaller app was first launched exclusively in 2009 by Blackberry. Later the app was released on Android and iOS platforms that could be used to manage calls with the help of the caller ID function.

It gained popularity as it accurately displayed the contact details of unknown callers and thus helped to avoid or block spam callers and telemarketers. But not many people prefer using Truecaller, considering it to be a privacy threat.

In this blog, we will first look at how Truecaller tracks and identifies all phone numbers, followed by which will be the methods of shutting down the Truecaller account.

How Truecaller Identifies the Callers?

Truecaller gains access to the address book of users to collect information about their contacts. This way, through crowd-based outsourcing, it collects the data and stores it in the databases. Thereby, it further identifies the number and displays it accordingly.

This means that even if someone doesn’t use the app, still their data will be available on the Truecaller database that is collected from other people’s phones. Therefore, many people prefer to Unlist their numbers from the Truecaller database.

Truecaller also collects and stores addresses associated with a landline number. Truecaller acquires this data from Telecom companies. Due to this reason, the residential address of a landline number can also be displayed to whoever you are calling, which may be far too risky to reveal to unknown people. The risk of exposure is not only limited to this sphere but even to the extent of discoverability on Google’s search engine.

Final Thoughts

Therefore, it can be noted that the above-described methods can be used to delete your number from Truecaller and also to remove the account related private information from their databases.

Occasionally, it has been noted that it doesn’t remain off the records forever because tracking continues to happen through other people’s number every time a new person downloads the app and provides access to their contacts list. So, this can lead to the reappearance of the number in the Truecaller database again.

To prevent this from recurring, again and again, you can keep verifying with Truecaller if your number is appearing with them and request them to delete your number.

How to Fix HYPERVISOR ERROR 0x20001 in Windows 11/10 

October 8, 2026
0

HYPERVISOR ERROR 0x20001 is a Blue Screen of Death (BSOD) error that indicates Windows cannot launch a VM (Virtual Machine), as the hypervisor has encountered a critical issue and can no longer function. The hypervisor supports virtualization technologies such as Hyper-V, VirtualBox, and VMware, managing how system hardware communicates with virtual environments. When the hypervisor stops working, Windows stops virtualization operations to avoid data corruption.

You can fix it through the solutions in this article, including restarting your PC and disconnecting external devices, enabling virtualization in BIOS/UEFI, disabling Hyper-V, updating device drivers, and running system scans. Before moving into the details, it is important to understand the error and its causes.

What Is HYPERVISOR ERROR 0x20001

HYPERVISOR ERROR 0x20001 is a fatal condition that prevents the hypervisor from functioning safely. The hypervisor, or virtual machine monitor, allows a single PC to host multiple operating systems. In Windows, Hyper-V manages this function, and when it runs into problems, you get the HYPERVISOR_ERROR (0x00020001).

What Causes HYPERVISOR ERROR 0x20001

Windows 10 or Windows 11 hypervisor errors typically occur if virtualization is incorrectly configured or disabled in BIOS/UEFI, if Hyper-V conflicts with third-party hypervisors such as VirtualBox or VMware, if critical device drivers are outdated, or if the CPU or memory has hardware instability.

Whatever the cause may be, you can follow the guide below to fix it.

How to Fix HYPERVISOR ERROR 0x20001

To fix BSOD HYPERVISOR_ERROR 0x20001, you can restart your PC and disconnect external devices, turn on virtualization in BIOS/UEFI, disable Hyper-V, update outdated device drivers, fix RAM issues, perform SFC and DISM system scans, update BIOS, check Hypervisor Boot Configuration, turn off overclocking, uninstall the recent Windows update, and clean boot your computer. Below are these solutions in detail; follow them sequentially until the error disappears.

Fix 1: Restart your PC and remove external devices

Restarting your computer and disconnecting unnecessary USB or other devices is the easiest thing you can do to fix the HYPERVISOR ERROR 0x20001. If this does not solve the problem, then move to the complex solutions below.

Fix 2: Check and enable virtualization in BIOS/UEFI

Modern CPUs have virtualization extensions like AMD-V (also known as SVM mode) or Intel VT-x. BIOS/UEFI must have these extensions enabled for Hyper-V to function correctly. Hence, follow the steps below to check and enable them.

  • Restart your computer and press F2, Esc, or Del to enter BIOS/UEFI.
  • Find settings such as AMD SVM Mode or Intel Virtualization Technology (VT-x).
  • Configure these settings to Enabled.
  • Lastly, save the changes and restart your PC.

Fix 6: Run SFC and DISM scans

Missing or corrupt system files can cause virtualization errors, such as the Windows 11 hypervisor error. Hence, follow the steps below to run System File Checker (SFC) and DISM tools to repair system files.

  • Click the Start button.
  • Type cmd in the search bar.
  • Right-click Command Prompt in the search results and then click Run as administrator.
  • In the Administrator Command Prompt, copy and paste sfc /scannow.
  • Press Enter.
  • Next, copy and paste DISM /Online /Cleanup-Image /RestoreHealth.
  • Press Enter.
  • After the scanning is complete, restart your PC.
