Press Windows R, type msinfo32, and check "System Type": "x64-based PC" means 64-bit, "x86-based PC" means 32-bit. 2. In Settings, go to System > About and view "System type" to see the OS architecture. 3. In Control Panel under System, look for "System type" to confirm if the OS is 64-bit or 32-bit, which is essential for installing correct software, drivers, and understanding RAM limitations, with most modern systems being 64-bit.
You can quickly check whether your Windows is 32-bit or 64-bit using built-in system tools. Here’s how:

1. Using System Information (Recommended)
This method works on all modern versions of Windows (7, 8, 10, and 11).
- Press the Windows key R to open the Run dialog.
- Type
msinfo32
and press Enter. - In the System Information window, look for "System Type".
- If it says "x64-based PC", you're running a 64-bit version.
- If it says "x86-based PC", it's a 32-bit system.
This is the most accurate way because it shows both the processor architecture and the operating system type.

2. Through Settings (Windows 10 & 11)
- Click the Start button and go to Settings (or press Windows I).
- Go to System > About.
- Under Device specifications, check "System type".
- It will clearly state whether you're running a 64-bit or 32-bit operating system.
Note: Even if your processor supports 64-bit, the OS might still be 32-bit — this setting tells you what version of Windows is installed.
3. Using Control Panel
- Open Control Panel (you can search for it in the Start menu).
- Go to System and Security > System.
- Look for "System type" under the System section.
- Again, it will say either 64-bit Operating System or 32-bit Operating System.
Why It Matters
Knowing your system type is important when:

- Downloading software or drivers (many require 64-bit versions).
- Installing new applications that have separate 32-bit and 64-bit installers.
- Upgrading RAM — 32-bit systems are limited to about 4 GB of usable memory.
Most computers made in the last 15 years use 64-bit processors, and modern Windows versions default to 64-bit installations.
Basically, just check System Type in System Info or Settings — it’ll tell you everything you need.

The problem of slow booting can be solved by the following methods: 1. Check and disable unnecessary booting programs; 2. Turn off the quick boot function; 3. Update the driver and check disk health; 4. Adjust the number of processor cores (only for advanced users). For Windows 11 systems, first, the default self-start software such as QQ and WeChat are disabled through the task manager to improve the startup speed; if you use dual systems or old hardware, you can enter the power option to turn off the quick boot function; second, use the device manager to update the driver and run the chkdsk command to fix disk errors, and it is recommended to replace the mechanical hard disk with SSD; for multi-core CPU users, the kernel parameters can be adjusted through bcdedit and msconfig to optimize the startup efficiency. Most cases can be corrected by basic investigation

If you need to obtain the Windows 11 product key, the answer depends on how you get the system. 1. If the system is pre-installed (OEM authorization), the key is usually embedded in the firmware and cannot be directly accessed and will be automatically activated during reinstallation; 2. You can use BelarcAdvisor, ProduKey and other tools to extract the key from the system, but you must ensure that the source is trustworthy; 3. If purchased or activated through a Microsoft account, you can log in to account.microsoft.com to view the associated key and digital license; it is necessary to note that the retail key can be transferred, while the OEM key is usually bound to the original hardware.

When Windows cannot detect a second monitor, first check whether the physical connection is normal, including power supply, cable plug-in and interface compatibility, and try to replace the cable or adapter; secondly, update or reinstall the graphics card driver through the Device Manager, and roll back the driver version if necessary; then manually click "Detection" in the display settings to identify the monitor to confirm whether it is correctly identified by the system; finally check whether the monitor input source is switched to the corresponding interface, and confirm whether the graphics card output port connected to the cable is correct. Following the above steps to check in turn, most dual-screen recognition problems can usually be solved.
