Na moim kompie z Windows 10 zainstalowałam sobie WinRar 5.31 Beta i jestem z niego bardzo zadowolona. Nie aktualizuję go, bo wówczas moja licencja straci ważność. Działa sobie obok 7-zip, używam ich zamiennie. Polecam ów program. 
Version 5.80 beta 2
1. "Find files" and command line mode "i" commands:
a) if "Use all tables" option or "t" modifer of "i" command are used,
additionally to already supported ANSI, OEM and UTF-16 encodings
WinRAR will search the specified string in UTF-8 files as well;
b) better support for Unicode text strings;
c) better performance, especially for case insensitive search;
d) hexadecimal search output includes both text and hexadecimal
representation of found matches.
2. File and total progress bar is displayed when unpacking
tar.bz2, tar.gz, tar.lz, tar.xz, tar.z archives.
Previously only the total progress was displayed properly for tar.bz2,
tar.gz and tar.z. Neither file nor total progress was displayed
for tar.lz and tar.xz.
3. "File list/Files/Exact sizes" option also changes the file size format
in WinRAR status bar.
4. Added support for one more variation of TAR format archives.
5. Bugs fixed:
a) WinRAR extraction commands in Windows Explorer context menu
failed if -ag switch was added to rar.ini file.

32bit:Version 5.80 beta 3
1. "Export settings to file" command in "Options" menu saves both
HKEY_CURRENT_USER\SOFTWARE\WinRAR and HKEY_LOCAL_MACHINE\SOFTWARE\WinRAR
Registry data to Settings.reg, so user defined variables in HKEY_LOCAL_MACHINE\Software\WinRAR\Policy are also preserved.
Previously it exported only HKEY_CURRENT_USER\SOFTWARE\WinRAR data.
2. Bugs fixed:
a) previous beta versions failed to unpack ZIP archives with
mismatched order of local file records and central directory entries;
b) if we opened archive properies in Windows Explorer and selected
some text on "Comment" page, selection was lost when moving
the mouse cursor outside of properties dialog.

1. Bugs fixed:
a) if hard link was extracted over existing hard link with same name,
WinRAR could fail to properly set its file attributes;
b) turning off "Integrate WinRAR into shell" option did not remove
"WinRAR archive" and "WinRAR ZIP archive" items from Windows
"New" context menu;
c) extraction could hang infinitely when unpacking some corrupt ARJ
archives and corrupt ZIP archives with BZIP2 compression algorithm.
Pobieranie:Version 5.90 beta 2
1. Added extraction support for GZIP archives with optional header
checksum field.
2. If non-existent path was specified as a start-up folder
in WinRAR settings, previous versions displayed an empty file list.
Now the current folder is used instead.
3. Bugs fixed:
a) beta 1 could produce corrupt archives when using small
128 KB - 1 MB compression dictionaries with delta or executable
compression and source data size exceeding the dictionary size.
Version 5.90 beta 3
1. Bugs fixed:
a) in previous beta versions "Info" command failed to work properly
for a single selected file or folder outside of archive;
b) RAR4 archives compression ratio could be very slightly lower
than in WinRAR 5.80. It is restored to 5.80 level now;
c) non-English names in ZIP archives created by Windows XP integrated
ZIP tool could be corrupted when modified by WinRAR.
Version 5.91 beta 1
1. Dialogs are centered inside of WinRAR window similarly to WinRAR 5.80
and not inside of entire screen as in WinRAR 5.90.
2. When editing an archived file with external software, extra measures
are taken to reduce the probability of interfering with editor
and opening its temporary files while editor still may need them.
3. "Version to extract" field in archive properties opened from
Windows Explorer context menu provides the additional information
about ZIP compression and encryption algorithms, such as LZMA or AES.
This information was already available in WinRAR "Info" command,
but missed in archive information accessible from Windows Explorer.
4. "MS DOS" and "Unix" host OS types are recognized and included
for LZH archives in "Info" command. Previously the host OS field
was always "Unknown" for LZH archive format.
5. Files created by external editor and matching "Settings/Viewer/
Ignore modifications for" masks are never added to archive.
Previously WinRAR still added them if some file not matching
these masks was also created or modified.
6. Bugs fixed:
a) empty file names were displayed inside of some Unix LZH archives;
b) WinRAR could not process more than 999 7z volumes in a single set;
c) if user cancelled the user account control prompt after changing
"Integrate WinRAR into shell" option, a new state of this option
was displayed in "Settings" dialog, even though the actual state
of shell integration was not modified;
d) the main window size could be too small on the first run after
clean install with no previous WinRAR version present;
e) WinRAR could stop responding after editing an archived file
with external software in Windows 10 version 2004.
