📌 IMPORTANT NOTES ABOUT WINDOWS BETA (TIMEBOMB)

Welcome to the 100% genuine Windows Beta collection from Microsoft. Below are important notes for successful installation and troubleshooting common errors.

1. Note on Timebomb Mechanism

All Beta/Preview versions in this collection have an expiration date. If you install with the current time, the system will report an expiration error or continuously restart.

How to fix:

• Adjust BIOS: You must change the date in the virtual machine's BIOS to the exact time when that build is still valid.

• Disable time synchronization: Turn off the "Time Synchronization" feature in VMware/VirtualBox settings so that the virtual machine does not automatically update to 2026.

• Disconnect the Internet: Do not connect the virtual machine to the network during installation.

2. Common Errors and How to Fix

• Error "This build of Windows has expired": This is due to not changing the BIOS date or the virtual machine automatically synchronizing the time with the host machine. Please double-check your time settings.

• Blue Screen of Death (BSOD) during startup: This is often due to Windows Beta not recognizing modern SATA/SCSI hard drives.

• How to fix: Go to virtual machine settings and change the hard drive configuration to IDE.

• Product Key required error: Beta versions require a specific installation code. Search for "Windows Beta Product Keys" on forums like BetaArchive to obtain an official trial key.

• Missing graphics driver error (Aero not working): Vista Beta versions require a graphics card that supports DirectX 9. Install VMware Tools (an older, compatible version) to enable Aero Glass effects.

How to configure virtual machine software for Windows Beta

1. For VMware

To prevent the virtual machine from automatically using the time from the real computer (year 2026), you need to adjust the configuration file:

1. Completely shut down the virtual machine.

2. Find the folder containing the virtual machine, right-click on the .vmx file and select Open with Notepad.

3. Paste the following lines at the end of the file:

• tools.syncTime = "FALSE"

• time.synchronize.continue = "FALSE"

• time.synchronize.restore = "FALSE"

4. Save, then turn on the virtual machine, press F2 to enter the BIOS and adjust the date according to the Excel table above.

2. For VirtualBox

1. Enter BIOS: Press F12 or ESC when the logo appears to adjust the date.

2. Command to block time synchronization: Open CMD on your physical computer (PC) and type:

• VBoxManage setextradata "Your_Virtual_Machine_Name" "VBoxInternal/Devices/VMMDev/0/Config/GetHostTimeDisabled" 1
