Solved: Windows 7 Service Pack 1 (SP1)will not install

I have an Acer Aspire 5551-2036 running Windows 7 Home Premium. Each time I download SP1 and attempt to install it, the configuration gets to 8% then fails. I have ran System Update Readiness, troubleshooter, uninstalled all anti virus software, cleared out cache and deleted previous installed files that could cause problems.... short of restoring my unit is there another solution?

 

Have you checked if SP1 is already installed in your computer.

Click start/right click computer/select "properties".

 

Yes, service Pack 0..........error code is 0x800f0826

 

Are you trying to install Service Pack 1 through Windows Update? If so, try manually downloading it from here :

Then run it .

 

It is an old unit I didn't use for years.....

 

yes, that is my last option...

 

I have done a complete virus/malware cleanup with Norton, McAfee, Kaspersky, Malwarebytes, Panda, Webroot.

 

I had a computer that I spent more than a week on, doing everything to get SP1 installed. It just would not do it.
I finally resorted to downloading the ISO of Win 7 Home Prem with SP1. I burned the ISO to a DVD then I used my serial number on my COA and installed it that way.

Unfortunately the ISOs for Win 7 with SP1 have been moving around and closing so it is not easy to point you to a download that is guaranteed to work.
