JSI Tip 3709. QChain.exe is a safe way of installing multiple hotfixes with a single reboot.

In tip 1981, we installed multiple hotfixes, with a single reboot.

When using the unattended method of installing multiple hotfixes with a single reboot, it is possible to get the wrong version of a file installed. If a file is locked or in use, it is placed in the Pending File Rename queue, so it can be installed during a restart. If file X exists in multiple hotfixes, at differing versions, it is possible that the wrong one gets installed.

NOTE: See Qfecheck.exe.

Microsoft has released QChain.exe, which has the following benefits:

1. It version checks / clears duplicate entries in the Pending File Rename queue, so only the latest file version is installed.

2. It works on both Windows NT 4.0 and Windows 2000.

3. It is now the only supported method for installing multiple hotfixes with a single reboot.

To use QChain.exe:

1. Perform the application of hotfixes using the technique in tip 1981, but DO NOT reboot after the last hotfix, use the -z switch.

2. After all the hotfixes have been applied, run QChain.exe.

3. Shutdown and restart your computer.

NOTE: If you are doing this in a batch, use Shutdown.exe.
