By now, I presume that most of you may have installed Service Pack 1 for Windows 7, after checking its pre-requisites. But in case you have not, the reason being that you don’t see your Windows Updates offering it to you as a download, you may want to check out if any of these factors are responsible.
1. First and foremost, check if you have installed Updates 2534366 and 2533552 as these are pre-requisites and they have to be installed on your computer before Windows 7 SP1 will be offered in Windows Update
2. Are you running SafeCentral as your security software? Check if you are running version 188.8.131.52 or an earlier version. If so, you will have to update SafeCentral to its latest current version.
3. Intel integrated graphics drivers Igdkmd32.sys or Igdkmd64.sys are known to create issues too. Especially if their versions are
- Igdkmd32.sys (32-bit), versions 184.108.40.2064 through 220.127.116.111
- Igdkmd64.sys (64-bit), versions 18.104.22.1684 through 22.214.171.1241
These drivers cause problems with certain applications that use D2D (Direct2D). To check your versions, type dxdiag in start search and hit Enter to open the DirectX Diagnostic Tool. Here under Display tab, search for the drivers and their version numbers. You might want to update them to their latest current versions, states KB2498452,
4. If you have used vLite to customize your Windows 7 installation, well, you are going to face problems in this case. You may not expect Windows Update to offer you the option to install Windows 7 SP1 in this scenario.
What you can do if you have tried and addressed the above, is that you can download Windows 7 Service Pack 1 and see if you can install it.
