A Virtual Machine, Laptop or Computer running Windows XP is Slow to Startup and/or Applications take a long time to load

These two issues can occur for two different reasons, a corrupt file in the Windows Prefetch Folder or it could be that the Prefetch Folder is cluttered.

To resolve these issues you need to delete the contents of the C:\Windows\Prefetch folder and then restart your computer.

The Prefetch folder is just a cache of recently used application executables and will be recreated based upon the applications you use most frequently.  Over time the folder becomes cluttered with rarely used and prefetched applications hence the launch of applications becomes slower.

You may find following the clear down of the Prefetch folder and reboot that the first time you open each application it is still a little slow, ths is because Windows will automatically re-add the application on its first launch to the prefetch folder.  After your first use of the common applications everything should now be much faster and you should find startup times have been reduced.

Microsoft Windows 7 – Service Pack 1 and Microsoft Windows Server 2008 R2 Service Pack 1 – How to Easily Free Up Some Disk Space

Have you started to notice that C drive is getting a little full or do you just want to have a spring clean, well you may not realise it but when you installed Service Pack 1 onto your lovely Windows 7 machine or Windows 2008 R2 Server that Microsoft very sensibly backed up all the old system file before replacing them with new ones.

Assuming that you have had Service Pack 1 installed for sometime without issue it may be good to know that you might be able to reclaim some disk space by dumping these obsolete system files.

Simply launch an elevated Command Prompt by right clicking “Command Prompt” and selecting “Run as administrator”.  Once you are in a command prompt simply paste in the following:

DISM /online /Cleanup-Image /SpSuperseded

Be patient with this command as it will need to enumerate a large number of files and could take up to 60 minutes to complete.  Once finished I would recommend a reboot.

Windows 7 and Server 2008 R2 all use an imaging environment to install so with this command we are launching Deployment Image Servicing and Management (DISM) and then telling it to remove any of the superseded service pack files.  If you do not have any files to remove, might be because someone else has already removed them or your computer/server may have already come with Service Pack 1 pre-installed/integrated.  In this instance you will get a message like the one below, you will also get this if you try to run the command a second time after all the old files have already been removed.
