Create new String value with any name, like 1 and set its value to the desired program's EXE file.
e.g., If you want to restrict Google Chrome, then create a String value 1 and set its value to googlechrome.exe. If you want to restrict more programs, simply create more String values with names 2, 3 and so on and set their values to the program's exe file.

25. Restricting Drives in My Computer
Go to following key:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\Explorer
In right-side pane, create new DWORD NoViewOnDrive and change its value as following:
3 : To Restrict A and B drives only.
4 : To Restrict C drive only.
7 : To Restrict A, B, and C drives only.
8 : To Restrict D drive only.
F : To Restrict A, B, C, and D drives only.
03FFFFFF : To Restrict all drives.
If you want more specific restrictions, like you want to restrict a combination of drives, you can use decimal no. instead of hexadecimal no. Following is a list for all drives decimal no.:
A: 1
B: 2
C: 4
D: 8
E: 16
F: 32
G: 64
H: 128
I: 256
J: 512
K: 1024
L: 2048
M: 4096
N: 8192
O: 16384
P: 32768
Q: 65536
R: 131072
S: 262144
T: 524288
U: 1048576
V: 2097152
W: 4194304
X: 8388608
Y: 16777216
Z: 33554432
ALL: 67108863
So if you want to disable a combination of drives, just sum their numbers and give the same value to NoViewOnDrive. e.g., for restricting C, D, E and F drives, give the value: 4+8+16+32 = 60
NOTE: You can also hide the drives using NoDrives DWORD value. The location and its value remain same as the above trick.
That's all. Above are some common restrictions, if you want to know about any specific restriction, please let us know.
NOTE: If you want to remove the restriction, simply delete the DWORD or set its value to 0
