Judging from the reported experiences of others who have tried to repair or
reinstall IE6 in similar circumstances, I would not recommend trying the
suggestion of my esteemed colleague, Doug Knox.
<QP>
Do not reinstall any version of Microsoft Windows in any way after you
install Internet Explorer 7. Do not upgrade in place or upgrade to a new
edition.

Best to resolve your current issue (get IE7 Beta uninstalled) instead.
Uninstalling IE7 Beta will return you to IE6 SP1.
Before proceeding, please read! =>

1. First try uninstalling via Add/Remove Programs. (Tip: Make sure Show
Updates box is checked.)
If IE7 isn't found there, try the following which is based on the notes of
MVP Sandi Hardmeier:
2. Run the commandline
%windir%\$NtUninstallie7bet2$\spuninst\spuninst.exe (IE7 Beta2)
%windir%\$NtUninstallie7bet2p$\spuninst\spuninst.exe (IE7 Beta2 Preview)
Replace %windir% (above) with the path to your Windows folder, most often
'C:\Windows'. Make sure Show Hidden File and Folders is enabled via Control
Panel > Folder Options.
or
3. Go to the key
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer
Right click on Internet Explorer > New String Value > Name that value
InstalledByUser (the value of the new String should be your User Account
name) > Uninstall IE7 via Add/Remove Programs.
NB: Some software (for example CCleaner) deletes uninstaller directories
such as $NtUninstallie7bet2$ (or $NtUninstallie7bet2p$, for IE& Beta2
Preview). If the $NtUninstallie7bet2$ folder is empty, or has been deleted
completely, whether by third party software or manually to preserve disk
space, you will *not* be able to remove the Beta 2 Preview via Add/Remove
Programs or the commandline. If running System Restore does not resolve the
situation for you, then your only choice is to stay with the Preview, or
format your PC and install Windows anew. You will not be able to install
any future builds of IE7 while Beta 2 Preview is installed, nor will you be
able to run a Repair Install of XP.
