While you have not specified it this is your home computer or a computer at another location, there are a variety of reasons this could have happened.
If your account is not the primary account on your computer, then the options for your account may have been changed to prevent you from doing this.
There are three simple methods to change your desktop. First, the method you have tried. Second, go to your control panel, under display. Finally, right click on an image, and set it as background.
If you cannot access you control panel, then your computer has been set to not allow your account to do so. In this event, you will need to ask the owner/administrator to change your account settings.

Before ANYTHING else, force your antivirus to scan your entire HD. Now. On a 160 Gig one, the scan will take 30 mins +.
After the scan finishes perform a Full System scan w/ AdAware spyware remover. The default is "Smart System Scan" - change the settings to "Full".
THEN run cleanup & defrag

4:By freeing disk space, you can improve the performance of your computer. The Disk Cleanup tool helps you free up space on your hard disk. The utility identifies files that you can safely delete, and then enables you to choose whether you want to delete some or all of the identified files.
Use Disk Cleanup to:
• Remove temporary Internet files.
• Remove downloaded program files (such as Microsoft ActiveX controls and Java applets).
• Empty the Recycle Bin.
• Remove Windows temporary files.
• Remove optional Windows components that you don't use.
• Remove installed programs that you no longer use.
Tip: Typically, temporary Internet files take the most amount of space because the browser caches each page you visit for faster access later.
To use Disk Cleanup
1.
Click Start, point to All Programs, point to Accessories, point to System Tools, and then click Disk Cleanup. If several drives are available, you might be prompted to specify which drive you want to clean.
Disk Cleanup calculates the amount of space you will be able to free.
Choose the files that you want to delete.
3.
Clear the check boxes for files that you don't want to delete, and then click OK.
4.
When prompted to confirm that you want to delete the specified files, click Yes.
After a few minutes, the process completes and the Disk Cleanup dialog box closes, leaving your computer cleaner and performing better.
Speed Up Access to Data
Disk fragmentation slows the overall performance of your system. When files are fragmented, the computer must search the hard disk when the file is opened to piece it back together. The response time can be significantly longer.
Disk Defragmenter is a Windows utility that consolidates fragmented files and folders on your computer's hard disk so that each occupies a single space on the disk. With your files stored neatly end-to-end, without fragmentation, reading and writing to the disk speeds up.
When to Run Disk Defragmenter
In addition to running Disk Defragmenter at regular intervals, optimally monthly, certain events warrant running the utility outside of the monthly rule of thumb.
You should run Disk Defragmenter under the following circumstances:
• You add a large number of files.
• Your free disk space nears 15 percent.
• You install new programs or a new version of Windows.
To use Disk Defragmenter:
1.
Click Start, point to All Programs, point to Accessories, point to System Tools, and then click Disk Defragmenter.
Click Analyze to start the Disk Defragmenter.
2.
In the Disk Defragmenter dialog box, click the drives that you want to defragment, and then click the Analyze button.
After the disk is analyzed, a dialog box appears, letting you know whether you should defragment the analyzed drives.
Tip: You should analyze a volume before defragmenting it to get an estimate of how long the defragmentation process will take.
3.
To defragment the selected drive or drives, click the Defragment button.
After the defragmentation is complete, Disk Defragmenter displays the results.
4.
To display detailed information about the defragmented disk or partition, click View Report.
5.
To close the View Report dialog box, click Close.
6.
To close the Disk Defragmenter utility, click the Close button on the title bar of the window.
Detect and Repair Disk Errors
In addition to running Disk Cleanup and Disk Defragmenter to optimize the performance of your computer, you can check the integrity of the files stored on your hard disk by running the Error Checking utility.
As you use your hard drive, it can develop bad sectors. Bad sectors slow down hard disk performance and sometimes make data writing (such as file saving) difficult, or even impossible. The Error Checking utility scans the hard drive for bad sectors, and scans for file system errors to see whether certain files or folders are misplaced.
If you use your computer daily, you should try to run this utility weekly to help prevent data loss.
To run the Error Checking utility:
Important: Be sure to close all files before running the Error-Checking utility.
1.
Click Start, and then click My Computer.
2.
In the My Computer window, right-click the hard disk you want to search for bad sectors, and then click Properties.
3.
In the Properties dialog box, click the Tools tab.
4.
Click the Check Now button.
5.
In the Check Disk dialog box, select the Scan for and attempt recovery of bad sectors check box, and then click Start.
In most circumstances, select Scan for and attempt recovery of bad sectors.
6.
If bad sectors are found, choose to fix them.
Tip: Only select the Automatically fix file system errors check box if you think that your disk contains bad sectors.
go download the software and clean up your computer and guess what
your problem is over no more probelms
