Hi Harry,

Uninstalling a program removes it from your computer, but with Windows System Restore, it is possible to undo this action. The likelihood of successfully recovering the uninstalled program depends on how long ago it was uninstalled.
Any new programs that were installed after the program you want to recover was uninstalled will also be lost if you perform the restore, so you have to decide if it is worth the tradeoff.

Here's how to do it:

To restore system files and settings using a recommended restore point

1. Open System Restore by clicking the Start button . In the search box, type System Restore, and then, in the list of results, click System Restore. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
2. Click Recommended restore, and then click Next.
   If there isn't a recommended restore point, follow the steps below to choose a specific restore point.
3. Review the restore point, and then click Finish.

1. Open System Restore by clicking the Start button . In the search box, type System Restore, and then, in the list of results, click System Restore. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
2. Do one of the following:
   
   • If there is a recommended restore point, click Choose a different restore point, and then click Next.
   • If there isn't a recommended restore point, click Next.
3. Click the restore point that you want, and then click Next.To view the programs and drivers that will be affected (which could include programs that will be deleted), click Scan for affected programs.
4. Review the restore point, and then click Finish.

Also, if you have made a backup of those, you can use the below steps to recover the files:

To restore a deleted file or folder

1. Open Computer by clicking the Start button , and then clicking Computer.
2. Navigate to the folder that used to contain the file or folder, right-click it, and then click Restore previous versions. If the folder was at the top level of a drive, for example C:\, right-click the drive, and then click Restore previous versions.

   You'll see a list of available previous versions of the file or folder. The list will include files saved on a backup (if you are using Windows Backup to back up your files) as well as restore points, if both types are available.

3. Double-click a previous version of the folder that contains the file or folder you want to restore. (For example, if a file was deleted today, choose a version of the folder from yesterday, which should contain the file.)
4. Drag the file or folder that you want to restore to another location, such as your desktop or another folder.
   The version of the file or folder is saved to the location that you selected.

I hope this helps.
