SP2 - stalled at "reverting changes"

movemaine asked on
Sony Vaio laptop 64bit, sp2 update installed at 100% and then stated "Service Pack did not install. Reverting changes. Do not turn off your computer."

It has been stuck there for hours. I have shut down the machine & restarted, only to get the same thing.

It is completely stuck.

Hello movemaine,

Thank you for using Microsoft Answers forum. I suggest you restore your system to the day just before you installed the service pack.   

Start the computer in safe mode, and then use the System Restore feature

Starting your computer in safe mode prevents several software programs and drivers from starting. This can help troubleshoot the system problem.

To start your computer in safe mode and use the System Restore feature, follow these steps.

Start in safe mode:

1.     Make sure that there are no floppy disks, CDs, or DVDs in the computer, and then start the computer.

2.     Use one of the following procedures, as appropriate for your situation:

o    If a single operating system is installed, press and hold the F8 key as the computer starts. You must press F8 before the Windows logo appears. If the Windows logo appears, turn off the computer and then restart it.

o    If more than one operating system is installed, use the arrow keys to highlight the operating system that you want to start in safe mode, and then press F8.

3.     On the Advanced Boot Options screen, use the arrow keys to select the safe mode option that you want, and then press ENTER. Any of the safe mode options will work.

Use the System Restore feature:

1.     Click Start, type system restore in the Start Search box, and then click System Restore under the Programs section.

If you are prompted for an administrator password or for a confirmation, type the password, or click Continue.

2.     On the System Restore page, click Next.

3.     Select a restore point at which you know that the operating system was working, and then click Next.

The restore point should be a date before the first time that you experienced the problem that is described in the "Symptoms" section. To select a date, use the
Choose a different restore point option, and then click Next.

4.     If you are prompted to specify the disk to restore, select the hard disk on which the operating system is installed, and then click Next.

5.     On the Confirm your restore point page, click Finish.

6.     When the restoration process is complete, click Restart.

Here’s a link with other options and an explanation of this process.
