1. If your registry modifications were in the HKCU hive, run System Restore from another administrative user account.

2. You can access the Registry from the DVD Startup Repair / Command Prompt.... Type Regedit and browse to the modified registry values.

3. Try running System Restore from the Windows 7 DVD Startup Repair...

Have you tried to "Boot to last known good configuration"? During boot jam f8. it should come up with a menu. I believe it's under advanced options.

No... the last known good configuration starts Windows with the previous configurations that worked normally... I'm not sure it will work but you can try... Registry modifications may not apply as configurations.. but you can try it with F8 right after the beep... Tap it once every second until the Safe Mode options screen comes up and select "Last Known Good" option and press Enter. You can also try the Safe Mode option, and if you can logon try running System Restore.

To try and access the Registry from the Widows DVD:
1. type "DISKPART" (without quotes)
2. type "LIST VOLUME"
a list of disk volumes will come up on screen...
3. type "SELECT VOLUME #" (the drive number where Windows is installed)
4. type "REGEDIT"
5. browse to the registry keys where you made the modifications.

If none of these works, if you have a second computer available, download the Hiren's Boot CD/USB iso, burn it to a CD or install it on a USB pendrive, boot from it, and from the Registry tools, one of them (can't recall which it is at this moment) you can access the Widows Registry remotely.

You can also access the Registry from the Hiren's Boot CD as follows: Start Button > Run command > type REGEDIT > this will be the Hirens Boot CD registry.. to access your Windows Registry in the HDD, > Place the cursor on the HKLM Key > click on the File menu > Load Hive > browse to X:\Windows > System32 > Config > Software > type in the tittle bar: any name which for ease can be; "AAAAA" > select the registry key named AAAAA, > and browse the registry to the keys and values you want to make corrections to. After editing the values place the cursor on the key named AAAAA, > and from the File menu,> click on "Unload Hive". Next exit the Registry and restart the computer, > logon to Windows and see if the issues have been reverted.

The Hiren's Boot CD also includes a Registry application named Regreswiz (Registry Retore Wizard) that can perform a Registry restore sort of like System Restore but applied directly on the Registry, but the application has to find registry backups to use them. if none is available (no automatic registry backups have been made), the application will not find any and nothing will be done.

[strike]Just wondering how Windows got installed on the A: drive? it always installs on C and occasionally on D if C already has a Windows installation... it mostly installs on C and a second Windows 7 installation on a second partition, also installs as C and sees the first Windows installation as on D... so, Windows is designed to install by default on C and I find it very strange it should be on A:[/strike]

Another question is why rename the Program Files folder as "Prgram Files"? that may also be causing the issues.

EDIT: Strike that!!.. Guess you moved the Program files folder to the HDD which is connected through USB?

There's another way.. you can create a new folder on the HDD and name it Program Files > and with the program named "Application Mover", move each program folder to the HDD... A:\Program Files..
