Enable AHCI after installing Windows

I windows installed on an SSD with IDE option on BIOS. After changing to AHCI bios setting I windows was popping a BSOD.  The solution seemed really simple.

Before changing the value in BIOS i had to edit the mode. Open command prompt with administrative rights.  Run this command.

bcdedit /set {current} safeboot minimal

Reboot, change the bios entry,  start Windows and run this command (as administrator)

bcdedit /deletevalue {current} safeboot

Then reboot again.

In general, AHCI mode is faster than IDE emu mode. It allows for things like NCQ (native command queuing) and hotplug for SATA. System feels more responsive and smooth. This solution is tested and works on Windows 7, 8, 8.1

Also remember to check if TRIM is supported on your SSD.  While Windows is designed to automatically detect most SSDs, sometimes  it doesn’t work as intended. If you find the performance of your SSD is degrading (or just want to make sure TRIM is properly enabled), run this command (as administrator):

fsutil behavior query DisableDeleteNotify

It will give you one of two results, either a 0 or a 1. A zero indicates that TRIM is enabled correctly, a one means that it is not.

You can now enable TRIM with the following command.

fsutil behavior set DisableDeleteNotify 0

Or disable TRIM as follows

fsutil behavior set DisableDeleteNotify 1

windows activation

This solution is the only one worked for me… restoring windows to an earlier point did not work for me. So try the following

1) Click Start button.
2) Type: CMD.exe into the ‘Search programs and files’ field
3) Right-Click on CMD.exe and select Run as Administrator
4) Type: net stop sppsvc (It may ask you if you are sure, select yes)
Note: the Software Protection service may not be running, this is ok.
5) Type: cd %windir%\ServiceProfiles\NetworkService\AppData\Roaming\Microsoft\SoftwareProtectionPlatform
6) Type: rename tokens.dat tokens.bar
7) Type: cd %windir%\system32
8) Type: net start sppsvc
9) Type: slui.exe
10) After a couple of seconds Windows Activation dialog will appear. You may be asked to re-activate and/or re-enter your product key or Activation may occur automatically.

Things to know before you download Windows Vista SP1

Published: March 18, 2008


  • Windows Vista SP1 is available in English, French, German, Spanish, and Japanese. Other languages will be made available soon.
  • Microsoft strongly recommends using Windows Update to download and install Windows Vista SP1 on single PCs:
    • The download size from Windows Update of Windows Vista SP1 for x86 is 65 MB (compared to 450 MB from the Microsoft Download Center).
    • The download size from Windows Update of Windows Vista SP1 for x64 is 125 MB (compared to 745 MB from the Microsoft Download Center).
    • Windows Update will recognize PCs with known problematic drivers and postpone downloading Windows Vista SP1 until the PC has updated drivers or other applicable updates. Using Windows Update will help ensure you have the most trouble-free update experience possible.
    • Some Windows Vista users may encounter an issue with a small set of hardware devices that may not function properly after updating a Windows Vista PC to Windows Vista SP1. This is an issue with the way the device drivers were re-installed during the Windows Vista SP1 update process, not with the drivers themselves—these drivers worked on Windows Vista RTM and they work on Windows Vista SP1. This problem is typically corrected by simply uninstalling and reinstalling the driver. We are working with the manufacturers of these devices to get the known problematic drivers and their install programs updated, and also on other solutions we can use to ensure a smooth customer experience when updating to Windows Vista SP1 using Windows Update. For new PCs provisioned with Windows Vista SP1, this is not an issue.
  • If you choose to install Windows Vista SP1 via the standalone installer available on the Microsoft Download Center, Microsoft advises that you first visit Windows Update and install all optional drivers. Read Knowledge Base Articles 948187 and 948343 for more information.
  • If you have a prior version of the Windows Vista SP1 beta installed, you must uninstall it prior to installing the final version. Use the Control Panel applet “Programs and Features” and select “View installed updates” from the top left of the task pane. Under Windows, look for “Service Pack for Windows (KB936330).
