HELP!!! SP1 Failure; Won't Get Past Configuring Service Pack.

Hello lmttag,

1.     Have you tried to start your computer in ‘Safe Mode’?

I suggest that you try to start your computer in ‘Safe Mode’ and check if you are able to boot going past the configuring updates sreen.

Follow the below steps to boot the computer to ‘Safe Mode’:

a.     Restart your computer if it is powered on.

b.     Tap the F8 key after your computer initially powers on.

c.      Once you see the Advanced Boot Options menu you can stop tapping.

d.     Use the up/down arrow keys to highlight your selection.

e.     Select Safe Mode and press Enter.

f.       Logon to your computer using an account with Administrator privileges.

If you are able to boot the computer in ‘Safe Mode’, I suggest that you do a System Restore on the computer choosing a restore point before installing Service Pack 1.

a.     Click Start, type system restore in the Start Search box, and then click System Restore in the Programs list.

b.     If you are prompted for an administrator password or confirmation, type your password or click Continue.

c.      In the System Restore dialog box, click Choose a different restore point, and then click Next.

d.     In the list of restore points, click a restore point that was created before you began to experience the issue, and then click Next.

e.     Click Finish.

Same exact thing here both machines with Windows 7 Home Premium. It never gets past 14 percent and it does exactly what you described. The only way i found to get out of it is boot to safe mode. It tries to configure at first but then says failed reverting changes. After a few minutes it reboots normally. However, sp1 is still not installed. There has to be an issue with the service pack itself. I'm seeing too many threads on forums with the same issue for it to be isolated.

Been banging my head against a wall for two days over this install of SP1.
Just found an answer that worked for me.

Give Full Permission to All Users/Desktop:

1. Go to Start Search, type in CMD.

  Right click on CMD and Open as Administrator

2. Type each command below, pressing enter after each command. When asked to confirm press Y and hit enter:

   cacls "C:\Users\Public\Public Desktop" /t /g everyone:f

   cacls "C:\ProgramData\Microsoft\Windows\Start Menu\Programs" /t /g everyone:f

 

3. Exit the CMD.

I have Windows 7 Home Premium also and experienced the same problem with one crucial exception. After installing and attempting to re-boot, it tried to configure, failed, reverted, tried to configure, failed, reverted, but then booted normally. Someone I work with said that it makes two attempts and then re-boots as if the whole thing never happened (2-1/2 hours later) and that's what it did. Have you waited through both complete iterations? There's a chance it may boot normally after. I would suggest trying it. If it tries to configure three times then yours is acting differently than mine.
 Still haven't installed it. Waiting to hear of a hotfix or patch. It's frustrating to waste 2-1/2 hours just to find out it fails. When it fails the first time you know it's going to fail the second time too but you can't stop it because you're warned not to turn it off. Good luck and if you're successful in installing it please come back and tell me how you did it.

I tried it but after pasting the first command and then Y, it said access denied. I ran it as administrator. I'm the only one who's ever used my laptop since I bought it new. Any ideas?
