Install Old HP Printer Driver on Windows 7

For many old laser printers specially HPs, there is no dedicated driver for Windows 7. From HP website, I only could find the universal driver which I don’t like. Actually there are alternate print drivers we can use from Windows update, here is how:

1. Go to “Control Panel”, choose “Devices and Printers”, and click “Add Printer”
   
2. Choose “Add a local printer”
   
3. Under “Use an existing port” drop down list, select the old printer (I am using a networking shared printer HP LaserJet 1200)
   
4. In the page “Install the printer driver”, if you couldn’t find the driver for the old printer, click “Windows Update”
   
5. Then you may need to wait for Windows to download the drivers
   
6. After the update is done, find the driver for the old print
   
7. Follow the steps to finish the wizard

How to Fix Acrobat X Pro Won’t Open

     Acrobat X Pro won’t start on Windows 7 (64-bit) recently. It just doesn’t respond whether I try to open PDF files with it or double-click to start the program. I am pretty sure I DID activation while I install it. After some researches, realized the reason might be I did NOT sign in. (how stupid software!!)
     I did the following, and it does the job for me:

1. Delete the file “C:\Program Files (x86)\Common Files\Adobe\Adobe PCD\Cache\Cache.db”
2. Open the program
3. Sign in with your username/password (if you don’t have, apply one)
4. Acrobat will be back

解决″Windows安装程序无法将Windows配置为在此计算机的硬件上运行”

     在安装Windows 7时，如果出现“Windows安装程序无法将Windows配置为在此计算机的硬件上运行”错误，往往是因为一些预装Windows 8的电脑在降级到Windows 7的时候缺少AHCI驱动，而Windows 8已经内置了这个驱动。
     解决这个问题，首先要下载AHCI的Win7驱动：

• 下载32位驱动
• 下载64为驱动

     把解压缩后的文件拷贝到U盘中待用，然后正常安装Windows 7，在选择分区的界面，选择“加载驱动程序”，然后找到U盘中的文件所在地，系统会自动检测到驱动程序，按照提示再继续安装Windows。
