Hi Everyone,
I am kindly asking for help with a fresh installation of Windows 7 Ultimate 64 bit on an Acer Aspire V3 -731 laptop. The specs from Speccy are:
Operating System
Windows 7 Ultimate 64-bit SP1
CPU
Intel Pentium B960 @ 2.20GHz 48 °C
Sandy Bridge 32nm Technology
RAM
4.00GB Single-Channel DDR3 @ 665MHz (9-9-9-24)
Motherboard
Type2 - Board Vendor Name1 VA70_HC (U3E1) 49 °C
Graphics
Generic PnP Monitor (1600x900@60Hz)
Intel HD Graphics (Acer Incorporated [ALI])
Storage
298GB Western Digital WDC WD3200BPVT-22JJ5T0 ATA Device (SATA ) 40 °C
7GB Generic Flash Disk USB Device (USB )
Optical Drives
HUAWEI Mass Storage USB Device
MATSHITA DVD-RAM UJ8C0 ATA Device
Audio
High Definition Audio Device.
Between August 23rd to August 25th, I backed up and formatted the hard disk, installed the operating system, Kaspersky Free antivirus, Service Pack 1 and required updates, drivers from Acer's website, Adobe Reader and other software and restored the backed up documents. I also installed 25 Updates during that period without any problems.
I was away in September and installed the rest of the Updates on October 2nd to 4th, eventually getting the "Windows is up to date" message after a battle with Update error 0x80092004 resolved by manually downloading and installing the Servicing Stack and SHA-2 updates from the Windows Update Catalog.
I checked the event viewer and found the following warning:

I checked the Bluetooth driver in device manager and decided to obtain the correct driver from Acer to replace the installed Microsoft driver thinking that it was the cause of the error. I downloaded and installed the driver from Acer and checked the event viewer to see if the issue had been resolved but instead, I found hundreds of warnings like this:

SFC found corrupt files but could not fix them. I ran SFCfix and SURT numerous times with no success.
I used the findstr command to analyze the CBS log and found that iassdo.dll.mui was corrupt.
I then started the long journey, wandering around the internet looking for a solution. Along the way, I discovered that if you change the .mui extension to .jpg you get a Peacock picture which I tried but only got a picture that looked like leaves. A Google search for iassdo directed here via a link to a similar problem that was solved here.
Other sites suggested that the Windows disk is a pirate copy so I downloaded MGADiag and The Ultimate PID Checker v1.2.0.606 Блин by janek2012 to check if it is legal and they reported it is ok.
I also ran the slmgr /dlv command to check the licence.
I checked the downloaded Bluetooth driver file at VirusTotal as I could not find the file hash on the Acer download page. Kaspersky's Application Advisor reported that the hash is ok but the file is not digitally signed.
I also installed Microsoft Office 2007 but got the same warnings as the Bluetooth driver:

In addition, I used System Restore several times but undid all the restorations as they could not solve the problem. I even tried a repair with Tweaking.com repair in safe mode.
One other observation is that these iassdo files in the winsxs folder were modified on October 4th at 17:30 and all the others in 2009.
x86_microsoft-windows-n..ce_iassdo.resources_31bf3856ad364e35_6.1.7600.16385_ko-kr_baa6a5a449f63e2d

I installed a Korean Language Pack. Could that be the problem ?
The Korean language pack is not on the list of installed updates and Windows Update no longer offers it (the other languages are still offered) but the display language can be changed to Korean which means that it is installed.
One last thing: MicrosoftProgram_Install_and_Uninstall.meta.diagcab was used to uninstall the Bluetooth software and office 2007 and I did a disk check which found no problems.
That's all I can think of for now.
The CBS log is at CBS.zip
Thanks in advance,
