If you are planning to rebuild a ’slow’ computer by reinstalling Windows (XP or Vista) from scratch, here’s a pre-installation checklist + some time saving tips.

Fix Problems by Reinstalling Windows
As a SE, part of my job involves reviewing software which is so interesting but frequent installation (followed by un-installation) of software programs also tend to slow down the computer.

To deal with this problem, I did a clean installation of Windows last weekend and re-installed all the important software programs from scratch. As expected, the boot-up time has reduced and the computer’s performance has improved significantly. Luckily, this task is not as complex as it may sound but here are a few things you should remember before taking the plunge:

Pre-Installation Checklist

1. Get Magical Jelly to retrieve a list of product keys that were used to install Windows and Microsoft Office on your computer. Print this information.

2. Get Belarc Advisor to create a detailed report of all software programs, hotfixes and hardware devices available in your system. Print this report as well.

3. Uninstall all software programs that had to be activated at the time of installation (e.g. Adobe Creative Suite or Microsoft Office). It’s important that you do a proper un-installation of these programs through Add/Remove Programs because simply deleting the folder from Program Files directory will not free up the license on the manufacturer’s activation server.

4. Install Driver Max to create a backup of all device drivers currently installed on your system. This will come handy after reinstallation incase you are not able to locate the driver installers on the vendor’s website.

5. Create a backup folder on c: (say c:\old_files) and add the following files to this folder

i. Your Outlook pst file that has all the mails, contacts, tasks and other Outlook items.
ii. If you have purchased any custom fonts, copy the relevant ttf files from the c:\windows\fonts folder. c. All documents, Live Writer drafts, pictures, music and videos from your My Document folder.
iii. Backup your custom dictionaries from Firefox, Microsoft Word, Live Writer, etc.
iv. Export all browser bookmarks and copy them to the backup folder.
v. Open your Firefox add-ons window, take a screenshot and paste that image in the backup folder. This is a good way to remember your favorite Firefox extensions.
vi. Export your podcast subscriptions in iTunes as as OPML (XML) file.
Product keys (serial numbers) of all licensed software.
6. If you have a partitioned hard drive (say C: and D:), just copy* the backup folder created in step 5 to the D: drive. If you don’t have a partitioned hard disk or if the size of partition is small, install Live Mesh, add c:\old_files folder to your Live Mesh account and wait until all the files are uploaded on to the web. Mesh offers 5 GB of space and it may therefore be a good idea to burn all the heavy files (like videos, music, etc) onto a DVD instead of transferring them online.

Re-Install Windows from Scratch

Now is the time to do a clean installation of Windows. This is probably the easiest part. You can either boot your computer from the original Windows installation CD** or, while you are running Windows, pop-in the installation CD and run the setup.exe program just like you would install any other Windows app. Always choose "Fresh Installation" instead of "Repair".
**If you installation media doesn’t include the latest service packs, try creating one yourself. Windows XP with SP3 is available as a downloadable ISO while you can slipstream SP1 into Vistafairly easily.

Post-Installation Tips

It can take around 30 minutes (or more) for the whole installation to finish. Now jump to the Windows Update website and let your browser download all the hotfixes, security updates, driver updates, etc. If your computer is unable to connect to the Internet, chances are that your computer doesn’t have the proper network drivers. No problem as you can easily get the drivers from the dump that you created using DriverMax utility.
If your display is acting funny or there’s no audio, just install the right drivers from the vendor’s website (preferred approach) or use your backup media. Once all the patches are installed, Windows Vista users can free up few gigabytes of disk space by making SP1 permanent. Windows XP users may skip this step.

Now turn on the Firewall and install all the other software programs and associated updates in any order. The next important step is to clone your disk image via DriveImage XML (free software),Acronis True Image or Norton Ghost. Windows Vista Ultimate also comes with a "Backup & Restore Center" that you may use to create a complete backup image of your entire computer to another drive, external disk or a DVD.

These disk images will come very handy after few months when your Windows PC get slow again. You won’t have to repeat the rebuilding exercise as the PC can be easily restored to the original state through these disk images.
Don’t experiment on your main PC

If you are tech enthusiast who loves to try new software / browser add-ons, I would strongly recommend that you don’t install these software on your main system - instead get Virtual PC (it’s free), create a Windows XP / Windows Vista virtual machine and use that environment as your new playground.
Another recommendation - do get a cane of compressed air to remove all the dirt from components inside the computer case. Sometimes software may not be the reason behind your slow and slugging PC - the culprit could be the dust sticking on the CPU heat sink.

The first thing I want you to do is install PC Decrapifier - this will detect and remove all the unwanted trial programs that came pre-installed with your machine.

 

Next you should install Firefox - it’s an Internet Explorer like web browser but slightly better. Instead of using browser bookmarks, try the delicious add-on to save the addresses of all your favorite websites. Another add-on that you should install is Iterasi - web pages come and go but Iterasi will permanently archive your favorite web pages.

 

You should create two email accounts one Gmail.com - share the primary email address with your friends and family but for everything else (like the newsletter and shopping deal alerts) always use the secondary email address. If you come across a site that requires registration, generate a temporary email address from 10MinuteMail.com and enter without sharing your main email.

 

With so many websites around, you’ll soon find it very hard to remember all those passwords so get into the habit of putting down all the different passwords into KeepPass from day one.

 

If you plan to carry laptop in public places (like the Library), get this Laptop Alarm software that will emit a loud sound if someone tries to shut down your computer or remove the power cable. Laptop thefts are not so uncommon after all.

 

The best alternate for Microsoft Office Google Docs - it has all the basic feature you would need in an Office suite including templates for tracking expenses and utility bills. You can use your primary Gmail address to log into Google Docs.

 

Sometimes your friends will send you documents, images or video clips that won’t open on your computer - that’s because you don’t have the right viewer software on your machine. You can simply go to zamzar.com and convert the file into some simple format (like avi for video, jpg for images, doc for documents, mp3 for songs, etc.) that you computer can play/open.

 

If the computer contains too many programs that you’ll rarely or never use, get the Revo Uninstallerto get rid of such programs permanently. To free up additional space on the hard drive, useWinDirStat to learn about file folders that are occupying the maximum space on your computer and delete the unnecessary files.

 

Be very careful when deleting files on your computer but if you ever delete something important accidently, Recuva may help you recover all those erased files. It even works with the memory card of your digital camera.

 

To download pictures from your digital camera onto the computer, get Windows Live Photo Gallery. This software can also upload your photos to our common family Flickr account so everyone gets to see your pictures even though we are several hundred miles away from you.

 

If the computer is not able to play your huge collection of DVD movies, you’re probably missing some codecs  -  just download the VLC player and the DVDs will play just fine.

 

You should also get Live Mesh - it will allow us to share files and documents with each other privately plus you can use Mesh to backup important files onto the cloud (I mean the web).

 

Google Talk is the best IM available, very lite weight, but if some of your online friends use other chat software (like Yahoo! Messenger or AOL), you can easily connect with them through Mirandaor, if you don’t want to install any software, use Meebo.

 

Another thing - do open an account at PayPal and link it to your main credit card as this will make online shopping easier. If you ever have a problem with PayPal or something isn’t clear, just call their toll-free 1-800 support number from your browser using Gizmo.

 

If your current voice plan is too expensive, I suggest that you download Skype - it lets you make calls from the computer to any landline or mobile phone at much cheaper rates. We can also use Skype to have video chats on weekends but if you don’t find me online, just send me a video email with Eyejot.

 

If you have newspaper clippings, bill receipts and business cards lying in the closet, just take a picture of them separately using the camera of your mobile phone and transfer them to the computer with Evernote - it will turn your "paper" documents into digital format that is always so easy to find and manage.

 

When planning a movie or weekend dinner with friends, you can send all of them a quick reminder for the event via phone and SMS for free using Notifu. If you’re inviting people at home for a party, head-over to sites like VideoJug.com, SuTree or 5min.com for new ideas about food, cocktails, party games, etc.

 

If you ever need to fax a document somewhere, just go to FaxZero, upload the document and fax it for free. FaxZero is only available for fax numbers of US or Canada but for international numbers, you may try eFax.

 

You can also consider dropping those magazine subscriptions that are delivered by snail mail - switch to Zinio instead that delivers the same magazine but in digital format.

 

As far as I remember, you’re currently using an unlimited data plan for the Internet but if that’s not true, get BitMeter - it will help you visually monitor your bandwidth usage so you never exceed the plan limit. You may also want to download FlashGet for downloading big files from the Internet.

 

If you notice carefully, some websites add an orange colored icon in the browser address bar (go tocnn.com to see a live example) - this icon means that you can get updates about new articles posted on that site automatically without having to visit the site again and again. If that’s the case, go to Feed My Inbox and type the address of that website - you’ll be notified automatically via email.

 

When browsing the web, you’ll frequently come across photographs, web pages and videos that you’ll want to share with us (your family members) - you could either send the link in a group mail or better still, simply create an account at Tumblr and start saving all the "interesting" stuff there.

 

And if you ever find yourself spending too much time on the computer, get RescueTime to know about websites where you spend most of your time.

 

There are a few other things that I want to do on your computer like installing a hosts file and configuring OpenDNS so that sites load quickly on your machine. These however require some geeky knowledge so I will try configuring them from here itself via CrossLoop - a remote desktop access tool.
