Remove Windows Activation Key & Licence

To remove windows activation key and Licence follow these steps:

 

  1. Open a command prompt as an Administrator.
  2. Enter slmgr /upk and wait for this to complete. This will uninstall the current product key from Windows and put it into an unlicensed state.
  3. Enter slmgr /cpky and wait for this to complete. This will remove the product key from the registry if it’s still there.
  4. Enter slmgr /rearm and wait for this to complete. This is to reset the Windows activation timers so the new users will be prompted to activate Windows when they put in the key.

Three Ways To Access Linux Partitions (ext2/ext3) From Windows On Dual-Boot Systems

This article was originally published here



If you have a dual-boot Windows/Linux system, you probably know this problem: you can access files from your Windows installation while you are in Linux, but not the other way round. This tutorial shows three ways how you can access your Linux partitions (with ext2 or ext3 filesystem) from within Windows: Explore2fs, DiskInternals Linux Reader, and the Ext2 Installable File System For Windows. While the first two provide read-only access, the Ext2 Installable File System For Windows can be used for read and write operations.

I do not issue any guarantee that this will work for you!

Reverting back to windows boot loader

1. Remove the Ubuntu partitions (EXT3 and SWAP) and resize the Windows partition (NTFS) to use that space.

To do this, you can follow the blog post I made which uses the Gparted LiveCD. The NTFS partition is Windows, and the EXT3 and SWAP partitions were created by Ubuntu.

2. Fix the MBR (Master Boot Record) so that Windows will boot, instead of GRUB.

Boot from the Windows XP CD.
Rress the “R” key in the setup to start the restoration console.
Select your windows XP installation from the list, and enter the administrator password.
Enter the command: “FIXMBR” (without the quotes) at the input prompt and confirm the next question with a “Y” (without the quotes).
Use exit to restore the computer.

If you do not have your Windows XP cd, then you can use the SuperGrub LiveCD to fix your MBR.

Another option is to boot to a floppy and use “FDISK.EXE /MBR”, but the first two options are much better. Good luck!

How to stop windows making automatic diskcheck on start up

There are some people suggested to edit the registry but the proper way to disable CHKDSK from starting up is using the /x switch on chkntfs command in command prompt. The /x switch will exclude a drive from the default boot-time check. If you have drive C: as your hard drive, then the command to disable chkdsk from scanning C: drive would be:

chkntfs /x c:

If you have 2 drive, C and D, you can disable chkdsk with the command below

chkntfs /x c: d:

then go ahead and reboot.
